When installing and using this electrical
equipment, basic safety precautions should
always be followed, including:
READ AND FOLLOW ALL INSTRUCTIONS
WARNING - RISK OF CHILD DROWNING
Extreme caution must be exercised to prevent
unauthorized access to the spa by children.
WARNING - To reduce the risk of injury, do not
permit children to use the spa unless they are
closely supervised at all times.
WARNING - RISK OF ELECTRICAL SHOCK
Install the Control Module at least 5 feet (1.5m)
from the inside wall of spa, using non-metallic
plumbing.
DANGER-RISK OF ELECTRICAL SHOCK Do
not permit any electrical appliance, such as a
light, telephone, radio or television within 5 feet
(1.5m) of the spa.
A bonding lug has been provided on the outside
of the Control Module electrical control box. This
lug permits the connection of a No. 8 AWG
(8.4mm²) solid copper bonding conductor
between the Control Module and all other
electrical equipment and exposed metal within 5
feet (1.5m) of the Control Module.
WARNING - To reduce the risk of injury to
persons within the spa, never remove, or alter in
any way, the grates or covers on the suction
fittings in the spa. Never operate the Control
Module if the grates or covers on the suction
fittings are broken or missing.
WARNING - Prolonged immersion in water hotter
than 104EF (40EC) may cause hypothermia. The
causes, symptoms and effects of hypothermia
may be described as follows: Hypothermia
occurs when the internal temperature of the body
reaches a level several degrees above the
normal body temperature of 98.6EF (37EC). The
symptoms of hypothermia include dizziness,
fainting, drowsiness, lethargy and an increase in
the internal temperature of the body. The effects
of hypothermia include (1) unawareness of
impending hazard, (2) failure to perceive heat, (3)
failure to recognize the need to exit the spa, (4)
physical inability to exit the spa, (5) fetal damage
in pregnant women, and (6) unconsciousness
resulting in a danger of drowning.
WARNING - The use of alcohol, drugs or
medication can greatly increase the risk of fatal
hypothermia. Leave the spa immediately if
nausea, dizziness or headache occur.
Immediately cool the body by taking a cool
shower or by applying cold towels or ice packs. If
the symptoms persist, seek medical attention.
WARNING - To reduce the risk of injury, before
entering the spa, the user should measure the
water temperature with an accurate thermometer
since the tolerance of water temperature
regulating devices may vary as much as ±5EF
(3EC).
The use of alcohol, drugs, or medication before
or during use of the spa may lead to
unconsciousness with the possibility of drowning.
The water in the spa should never exceed 104EF
(40EC). Water temperatures between 100EF
(38EC) and 104EF (40EC) are considered safe
for a healthy adult. Lower water temperatures
are recommended for extended use (exceeding
10 minutes) and for young children.
Since excessive water temperatures have a high
potential for causing fetal damage during the
early months of pregnancy, pregnant or possibly
pregnant women should limit spa water
temperature to 100EF (38EC).
Obese persons and persons with a medical
history of heart disease, low or high blood
pressure, circulatory system problems or diabetes
should consult a physician before using the spa.
Persons using medication should consult a
physician before using the spa since some
medication may induce drowsiness while other
medications may affect heart rate, blood pressure
and circulation.
Occasional users of the spa may not be aware
of all the potential risks associated with spa
usage. They should be made aware of these
important safety instructions.

DESCRIPTION
REMOTE OPERATED SPA & POOL CONTROL
The Lennovator is a remote operated spa & pool control system. It assumes that an external gas heater or
heat pump with temperature and hi-limit controls exists. The external heater and associated safety circuits are
not part of the Lennovator System.
The Lennovator System supplies a set of dry contacts which may be connected to the external heat control.
Since the Lennovator senses the water temperature, a set point may be set via the RF remote controlsystem.
The dry contacts operate in accordance with the set point; i.e. if the set point is higher than the actual water
temperature the relay contacts close and the external heater heats the water. If the set point is lower than the
water temperature, the contacts open and the water cools.
The temperature set point and dry contact interface does not compromise the built in safety features of the
external heater control system.
The Lennovator senses water temperature in the spa & pool mode; however the associated set point and dry
contact circuits do not function in the pool mode. The temperature control of the pool is external to the
Lennovator and is not a part of its control system.
The Lennovator System also assumes there is only one pumping system for both the pool and spa. When the
spa mode is activated via the RF remote control, a set of contacts are available to operate the pool/spa valve,
i.e. the valves are activated such that the water is pumped to the spa. If the pool is activated via the RF remote
control, the contacts are reversed and the valves are activated such that the water is pumped to the pool. The
Lennovator also has a hard wired control which may be used during maintenance.
This unit consists of 4 sub-units (See Figure 1):
1. RF Remote Control Unit
2. Hard Wired Remote Control Unit
3. Master Control Unit
4. Transceiver

REMOTE OPERATED CONTROL FUNCTIONS
1. RF REMOTE CONTROL UNIT (Figure 2)
This unit is a hand held battery operated device which
contains a key pad, LCD display with a transceiver unit
and associated electronics. This sub unit is used to
operate the master control unit and to receive and
display temperature and status data.
Note: The remote control unit is not water resistant.
Do not submerge in water.
2. HARD WIRED REMOTE CONTROL UNIT
(Figure 2A, page 4)
The hard wired remote unit will be referred to as the
maintenance panel. The operation of the hard wired
unit is identical to the RF remote unit except:
a.Power is derived from the master control printed circuit
board,
b.Communication with the master control is via hard
wire,
c.There is no address switch,
d.There is no sleep mode - display will always be active,
e.The display has back lighting features.
The back light will be energized by depressing the
status switch. The light remains illuminated for 4 hours.
If after 4 hours there has been no activity, the back light
will turn off automatically.
3. MASTER CONTROL UNIT
This unit operates portable spa or pool/spa functions
upon command from the remote control unit. It
interprets the data from the remote control unit via a
transceiver, and turns the spa/pool functions on and off.
The master control unit also has an external time clock
to operate the filter pump automatically. It also sends
temperature and status data back to the remote control
unit upon request from the remote control unit.
4.TRANSCEIVER
There are two identical transceivers. One of these will
be mounted piggy back on the printed circuit board in
the remote control unit. The other will be mounted piggy
back on the master control printed circuit board. The
transceiver is in compliance with FCC CFR 47 Part 2
and FCC CFR 47 Part 15 with data rates up to 5 kilobits.
The method of modulation and coding can be pulse
position, spread spectrum or frequency hopping.
Different RF frequencies and the various modulation
and coding methods are available as range and
interference free options. Areas that have little RF
interference may use the pulse position RF transceiver.
The spread spectrum or frequency hopping modulation
and decoding method will be used in areas of high RF
interference and where the transceiver pair requires an
increased range.
5. LCD DISPLAY
The LCD Display is custom designed. It has a 2 1/2 digit
screen segment display and 9 Icons.
DISPLAY MESSAGES
The display shows the following messages:
“SP” - Spa mode, heat function active
“PO” - Pool mode, heat function inactive

6. KEYPAD (Figure 2)
The keypad has nine switches which are used to perform the
following functions:
UP SWITCH
The up switch raises the temperature set point. Also if the
water safety hi-limit circuit has been tripped (water
temperature went over 112EF), it can be reset by depressing
the up and down switches together (providing the water
temperature has cooled down below 108EF).
When the up switch is held depressed, the transceiver will
continue to transmit the command and receive the updated
temperature set point on the display. (It will update in two or
three second intervals). When the desired temperature set
point is observed the up switch should be released. The set
point will increment in 5Esteps from 35EF to 80EF and in 1E
increments from 80Eto 104EF. 104Eis the maximum set
point that may be selected.

REMOTE OPERATED CONTROL FUNCTIONS
DOWN SWITCH
The down switch operates the same as the up switch with
the exception that it lowers the temperature set point. If
the up and down switches are depressed together, a reset
safety hi-limit command is initiated which will clear the
safety hi-limit emergency shut down providing the water
temperature is below 108EF.
STATUS SWITCH
The status switch performs two functions:
a.Turns on main power (VCC) if in sleep mode (RF
Remote Control Unit only)
b.Requests temperature and status information from the
master control unit.
HEAT SWITCH
The heat switch sends a heat command to the master
control unit which toggles the heat mode on or off. When
heat mode is on, one of two status icons will be displayed:
a.“HEATING” if the water temperature is below the
temperature set point, or
b.“READY” if the water temperature is equal to or above
the temperature set point.
When configured for inground pool/spa the pool/spa
valves will rotate to spa function when in heat mode and
remain there until heat mode is turned off.
NOTE: The filter pump and jet pump (if on) will turn off for
30 seconds while the spa/pool valves are operating.
JETS SWITCH
The “JETS” switch sends a jets command to the master
control unit which toggles the jets function on or off. When
the jets function is on, the jets icon will be displayed. The
jets function is on a 30 minute timer and will automatically
turn off at the end of 30 minutes.
LIGHT SWITCH
The “LIGHT” switch sends a light command to the master
control unit which toggles the light function on or off.
When the light function is on, the light icon will be
displayed. The light function is on a 4 hour timer and will
turn off automatically after 4
hours.
AUX-1
The “AUX-1" switch sends an AUX-1 command to the master
control unit which toggles the AUX-1 function on or off. When
the AUX-1 function is on, the AUX-1 icon will be displayed.
AUX-1 function will normally control the blower motor. The
AUX-1 function is on a 30 minute timer and will turn off
automatically after 30 minutes.
AUX-2
The “AUX-2" switch sends an AUX-2 command to the master
control unit which toggles the AUX-2 function on or off. When
the AUX-2 function is on, the AUX-2 icon will be displayed.
The AUX-2 function is on a 4 hour timer and will turn off
automatically after 4 hours.
AUX-3
The “AUX-3" switch sends an AUX-3 command to the master
control unit which toggles the AUX-3 function on or off. When
the AUX-3 function is on, the AUX-3 icon will be displayed.
The AUX-3 function will not be used in the portable spa
configuration. The AUX-3 function is on a 4 hour timer and
will turn off automatically after 4 hours.
7. ADDRESS SWITCH
There is an 8 digit switch inside the battery compartment,
from which an address word is derived. This address must
match the 8 digit switch in the master control unit. They must
match in order for the master control unit to respond to the
command. The eighth position of the switch must be off for
the battery saver time out mode (sleep) to work.
POWER
The RF remote is powered by an alkaline 9 volt battery. The
life of the battery will vary depending upon usage. The eighth
position of the switch must be off for the battery saver time
out mode (sleep) to work.
SLEEP CIRCUIT
The sleep circuit is designed to turn off the VCC if there has
been no action from the key pad for about 40 seconds. The
status switch must be depressed to wake it up.
FIGURE 2A

MASTER CONTROL UNIT FEATURES
The Master Control Unit is made up of four basic blocks:
1. Processor
2. Relays & Relay Control Logic
3. Power Supply
4. Transceiver
1. PROCESSOR
The processor controls all of the master control unit
functions except the time clock. The Processor is a
microchip P1C16C73. The processor’s tasks are
A. Water Temperature
B. Temperature Set Point
C. Heat Command
D. Status Command
E. Jets CommandAux-1
F. LightAux-2
G. Power on ConditioningAux-3
A. WATER TEMPERATURE
If the water temperature exceeds 109EF but is less than
120EF, a warning is sent to the remote unit and is
indicated by the water temperature flashing on and off. If
the water temperature exceeds 120EF, it will send a
message to the remote unit which will be displayed as
“OH” and shut down all functions.
B. TEMPERATURE SET POINT
Store a temperature set point from 35E to 80EF in 5E
increments or from 32E to 35E or 80E to 104E in 1E
increments. The temperature set point will be
incremented up by the “UP” command and down by the
“DOWN” command from the remote control unit.
Following each up and down command the processor will
send the temperature set point to the remote control unit
followed with the actual water temperature approximately
two seconds later. When a status command is received
the processor will send the temperature set point to the
remote control unit with the actual temperature date
following in approximately two seconds.
To set a desired temperature, simply press up or down
arrows until the desired temperature appears on the
display.
C. HEAT COMMAND
When a “HEAT” command is received from the remote control
unit, the processor will do the following:
1. Turn the filter pump on,
2. Activate the pool/spa valves to activate the spa,
3. Turn on the “HEAT ENABLE” command to the relay logic,
4. Compare water temperature with temperature set point,
5. If the water temperature is lower than the temperature set
point, it will turn on the heat command to the relay logic and
send back a status message to the remote control which will
include data to turn on the “Heating” icon or if the water
temperature is equal to or higher than the temperature set point,
it will send a status message back which will include data to turn
on the “Ready” icon. The heating and ready icons should never
be on at the same time.
6. When in the heat mode, the processor will periodically
monitor the water temperature against the temperature set point
and turn the heating command on or off to the relay logic (with a
1EHysteresis) as required to maintain correct water
temperature.
7. When a heat command is received while in heat mode, the
processor will go out of heat mode turning off heat enable
command and heating command (if on) to the relay logic. It will
then send back a status message to the remote control clearing
the heating or ready icon. The pump will stay on for 2.5 minutes
(fireman’s switch).
If the water temperature goes below 35EF, the processor will
automatically go into heat mode until the temperature reaches
40EF to prevent damage in freezing weather.
D. STATUS COMMAND
When a “STATUS” command is received from the remote
control the processor will send a status message back which will
always contain information to turn on or off the status icons, as
required; heat on or off and temperature set point followed by
actual water temperature, for approximately two seconds each.
E. JETS COMMAND
When “JETS” command is received from the remote control unit
the processor will turn on the jets command to the relay logic
and return a status message to the remote control unit. Another
jets command from the remote control unit will turn off the jets
command to the relay logic. If in jets mode for 30 minutes and
no jets command was received from the remote control, the
processor will automatically turn off the jets command to the
relay logic.

6
F. AUX-1
The AUX-1 will be normally used to operate a blower
motor. This command will be handled the same as the
“JETS” command.
G. LIGHT
The “LIGHT” command will be handled the same as the
“JETS” command except it will have a four hour time out.
H. AUX-2
The “AUX-2" command will be handled the same as the
”LIGHT" command.
I. AUX-3
The “AUX-3" command will be handled the same as the
”LIGHT" command.
POWER ON CONDITIONING
When power is applied to the processor, it will retrieve
the last settings and return to the last operating condition
prior to power off.
2. RELAYS AND RELAY CONTROL LOGIC
The “RELAY LOGIC” controls the built in relays.
A. LO PUMP (FILTER PUMP) RELAY K-1
This relay is operated from two sources:
1. Turns on when the “HEAT” command from the
processor is present and the “JETS” command from the
processor is off.
2. Turns on from the remote time clock if the “JETS”
command is not present.
This relay will open for 30 seconds when switching from
pool to spa and from spa to pool. This is to take pressure
off pool/spa valves while they are changing. This relay
will remain closed for 2.5 minutes (fireman’s switch) after
the pump is turned off if the heater was on to allow the
heater to cool down before turning off the water flowing
through it. Any time the “JETS” command is turned on,
“LO PUMP” will turn off but will come back on when the
“JETS” command is turned off providing any of the three
conditions are met.
MASTER CONTROL UNIT FEATURES
B. HI PUMP (JETS) RELAY K-2
“HI PUMP” relay will turn on any time it receives the “JETS”
command from the processor. When the jets off command is
received, the hi pump will turn off when these conditions are
met:
a.If still in heat mode the hi pump will go off and lo pump will turn
on.
b.If the heater was on and the heat mode is turned off at the
same time, hi pump will go off and lo pump will turn on for 2.5
minutes (fireman’s switch) and then go off unless the timer clock
is on, then it goes off for 30 seconds and back on again. Hi
pump will time out and shut down automatically in 30 seconds.
C. AUX-1 (BLOWER) RELAY K-3
This relay can be turned on or off at any time by generating an
“AUX-1" command. Aux-1 will time out and shut down
automatically in 30 minutes.
D. LIGHT RELAY K-6
This relay is turned on when the “LIGHT” command is present
from the processor. The light will time out and turn off
automatically in 4 hours.
E. OZONATOR RELAY K-7
This relay is energized if hi or lo pump is on.
F. HEATER RELAY K-12
This is the external heat command relay.
G. AUX-2 RELAY K-4
This relay will be turned on when the “AUX-2" command is
present. Aux-2 will time out and shut down automatically in 4
hours.
H. AUX-3 RELAY K-5
This relay will be turned on when the “AUX-3" command is
present.
I. POOL VALVE RELAY K-9
This relay turns on when the “HEAT ENABLE” command is
present. Pool valves operate on 24 VAC so both K-11 and K-9
contacts are set up to operate from an external 24 VAC
transformer. This relay is used in pool/spa applications. The
pumps are turned off for 30 seconds while the valve is turning.

Remote Mechanical Filtration Timer
This mechanical timer will override any “off” function of the lo
pump if a filtration cycle is programmed “on”.
3. POWER SUPPLY
The power supply is powered by a 40 VA 25.2 volt CT Class
2 transformer. It provides 24, 12 and 5 VDC to power the
logic board. A separate transformer is used to power the
external spa/pool valves for the Lennovator. The Lennovator
power supply and time clock are normally configured for 240
VAC input, but can be factory wired for 120 VAC.
4. TRANSCEIVER
The transceivers are mounted on a separate printed circuit
board. It is soldered onto the RF remote control unit and
plugged into the master control printed circuit board. It
operates in the 900 MHZ band with a range of 300 feet
nominal.
SUMMARY OF TIME DEVICE FUNCTIONS
FILTRATION TIMER OPERATION
FILTRATION TIMER OPERATION
Lennovator single timer systems include a 24 hour filtration
timeclock, which controls the pool/spa pump.
The filtration timer provides the ultimate in operating
efficiency and economy. The pool/spa water
can be filtered once daily or several times a
day, to maintain a sparkling clear, clean
condition with proper sanitizer distribution.
One single-speed pump system:When the
timer reaches an ON time, the pump will turn
on.
Two single-speed pump system:When the
timer reaches an ON time, the primary pump
will turn on.
One 2-speed pump system:When the timer
reaches an ON time, the pump will operate in
low speed.
For an initial setting, follow “Setting the
Timer” instructions and try 6 to 8 consecutive
hours a day, or set various ON times spaced around the
timer. Wait a few days and adjust as necessary to maintain
sparkling clear water with a minimum of ON times.

INSTALLATION
INSTALLATION
Install equipment and Control Module where most protected
from direct exposure to the elements.
The Control Module is contained in a U.L. listed rainproof
outdoor enclosure.
PANEL LAYOUT
The NEC requires the following when you connect motor or
accessory (Article 430 NEC):
a. Short circuit and ground fault-protection
b. Motor overload protection
c. Service disconnect within sight of motor
d. Thermal (heat) protection
e. Bond earth to ground.
To meet these requirements, install a sub-panel at the
equipment site with separate breakers for each load. Make
sure the motor(s) on the equipment have built-in thermal
protection. Use the grounding. Bond all equipment to the
earth ground.
GROUNDING
Connect the grounding terminal in the Control Module to the
grounding terminal on your electric service or supply panel.
Use a continuous green insulated copper wire, equivalent in
size to high voltage wires, no smaller than No. 12 AWG
(8.4mm).
JUMPER OPTIONS J6, J7, J8, J10 (See Figures 3 and 3A)
J6 - if the Lennovator is operated without the remote
maintenance panel control, a jumper must be installed
between pin 3 and 4.
J7 jumper is placed on the PC card if the heater is to be
inhibited (turned off) when high pump or blower is in
operation. This will be used for low power budget systems.
J8 jumper is placed on the PC card if a two speed (single
motor) pump motor is installed. If two separate motors are
used; (lo pump, hi pump) remove the jumper.
J10 is for an external water pressure switch. In Lennovator
configuration, the water pressure switch is part of the heater
assembly. For Lennovator configurations, place the jumper
J10 on the PC card.
TEMPERATURE SENSOR
The temperature sensor senses system water temperature
and activates the heater as necessary to maintain set point
temperature. If extended, the sensor lead should be less
than 30 feet, #22AWG. The temperature sensor plugs into
J5, pins 1 and 2 on the master Lennovator card (See
Figures 3 and 3A).
Figure 4 (page 9) is a representative temperature sensor
installation into a pool/spa system.

the wiring information contained in this manual, or on the
back of the field wiring access panel of the Lennovator
Control Module.
WARNING: Improper electrical connections or conductor
sizing may cause the Lennovator Control Module to operate
improperly, create the potential for electrical hazard, and
may void the warranty.
The electrical supply for permanently connected Lennovator
Control Modules (hardwired for 120V and 240V operation)
must include a suitably rated switch or circuit breaker to
open all ungrounded supply conductors to comply with
Section 440-52 of the National Electrical Code,
ANSI/NFPA70. The disconnecting means must be within
sight and readily accessible to the user of the equipment.
The electrical supply for permanently connected Lennovator
Control Modules must also include a suitably rated Ground
Fault Circuit Interrupter (GFCI) to comply with Article 680-42
of the National Electrical Code, ANSI/NFPA70.
These installation instructions are provided as guidelines for
use and interpretation by knowledgeable installers. Wire
size, number of circuits, size of circuit breakers, etc. must be
selected for the particular system being installed. Refer to
Appliance Data Label to determine specific electrical
requirements.
CHECK ALL WIRE CONNECTIONS
Check all high voltage terminals for tight/secure connection.
Check all low voltage terminals for tight/secure connection.
Check the grounding wire for proper connection from the
Lennovator to sub-panel and main panel.
CHECK HEATER
Check heater for high limit protection.
Check heater for pressure or flow switch protection.
Check the connections of control terminals to the heater for
proper connection.
CHECK CONTROL PANELS
Make sure the remote control panel is accessible.

INITIAL START UP
INITIAL START UP
1.Open all valves in the water inlet and/or water outlet
to allow water to flow into the pump.
2.Fill the pool and spa with water following the
manufacturers instructions.
3.Check all plumbing connections for leaks.
ONCE THE POOL AND SPA ARE FILLED WITH
WATER (BETWEEN 40 AND 104EF) COMMENCE
START UP PROCEDURES
You must successfully complete all of the steps in this
procedure. If you encounter a problem, check and
repair your installation immediately and begin the
procedure again.
4.Turn power OFF.
5.Turn timer(s) OFF.
6.Verify water temperature is between 40 and 104EF
7.Turn power ON.
SPA WATER TEMPERATURE SETTING
#The spa water temperature is controlled by the
maintenance control or the wireless remote control.
To set the spa water temperature, refer to the
temperature setting instructions.
#Do not expect to feel hot water coming from the jets.
#The length of time it takes for the spa water to reach
the desired temperature depends on several factors:
Water temperature at start
Ambient air temperature
Quantity of water in spa
Insulating qualities of the spa cover and enclosure
#An insulating cover should be kept on the spa at all
times when not in use. Also, remember that
prolonged use of the air system and hydrotherapy jets
when using the spa will have a significant cooling
effect on the spa water.
LCD WARNING DISPLAYS
High Temperature Warning
Digital temperature displays will flash when water
temperatures range between 109EF and 120EF
Hi Limit Reached
System will automatically lock out the heater in spa
mode whenever the water temperature reaches 120EF.
In the event that the water reaches this preset hi limit,
the warning message “OH” (Over Heat) will replace the
digital temperature display. As the water cools to
below 120EF, the OH warning will be replaced by an
alternating display that shows the actual spa water
temperature and “HL”(Heater Lockout). Flashing
temperature and “HL” display continues until the hi limit
is manually reset. Manual reset is accomplished by
depressing the temperature up and down buttons
simultaneously.
SPA SHOULD NOT BE USED UNTIL THE SYSTEM
HAS BEEN INSPECTED AND REPAIRED
Inoperative Temperature Control
In the event that the temperature control system fails,
one of two warning messages will appear on the LCD
display:
OP - Temperature sensor has failed in the open
position.
SH - Temperature sensor has failed due to electrical
short circuit.
SPA SHOULD NOT BE USED UNTIL THE SYSTEM
HAS BEEN INSPECTED AND REPAIRED
