PoolWarden measures pH, sanitizer and temperature on up to two bodies of water and will control
the appropriate feed equipment to keep the measurements within a preprogrammed range. Using ORP
(oxidation reduction potential) technology the control of sanitizer takes into account the effects of pH, and
a pH lockout feature is also included for high pH values. Controls chemical feed equipment using relays to
keep the pool or spa water in balance. Water measurements are taken continuously while PoolWarden's
internal relay programing determines if chemical adjustments are needed. PoolWarden then
communicates the adjustment signals through relays which control the chemical feed equipment.
PoolWarden also contains additional dry-contact auxiliary relays that can be used to control
heaters, pumps, chlorine backup and external alarm notifications.
PoolWarden Plus
When adding the PW-Plus communication module, the software feature set will also be updated. Where
there are differences that will be pointed out.
System Components
tCONTROLLER: PoolWarden is a microprocessor based, modular automation system that is capable of
continuous monitoring locally onsite or remotely offsite.
tINTERFACE: PoolWarden uses a 16-button built in keypad, and an easy to read 80 character liquid crystal
display. The display’s internal back-light provides controller viewing in pool rooms with low light.
tMEMORY: PoolWarden is designed with nonvolatile memory which preserves all internal programming in case
of power loss. Internal memory is preserved for up to 10 years without having power applied.
tRELAYS: PoolWarden S (single pool) includes 4 relays (2 of which are dry contact relays). PoolWarden
D (two pools) includes 8 relays. Four of the 8 relays are dry contact relays (2 for each body of water).
tSENSORS: ORP, pH, Temperature, flow and optional free chlorine.
tVOLTAGE: Requires 120VAC input voltage in North America and 240VAC input voltage in Europe.
tSECURITY: PoolWarden is designed with a lockable enclosure and provides up to four levels of password
security protection (Admin, Tech, Service and Guest) for both local onsite and remote offsite interaction with the
controller.
tCOMMUNICATION: PoolWarden can connect to the Internet for direct monitoring, setup, and data interface by

Mounting PoolWarden
Turn off any heaters, pool or spa circulation systems, chemical feed pumps or any related shut-off valves
or equipment and relieve pressure from the filtration system. Find a suitable mounting location near a
120/240 VAC power source that meets the following criteria:
tFacilitates a combined (influent & effluent) maximum tubing run of 30’.
tDo not mount controller above electrical sources or electrical equipment.
tAt least 10’ away from any pool, spa or body of water and not accessible to the public.
tAway from corrosive materials including fumes and physical hazards.
tNot in direct sunlight or directly above or near any heat source.
tFor 240 VAC, ability to hard wire with GFCI (ground fault circuit interrupter) protection.
Securely mount controller, or the optional controller backboard, vertically on the wall using supplied
screws or appropriate fasteners for the wall construction. Product shall be positioned such that the power
supply cord plug, which is the disconnect device, can be easily accessible.
Flow Cell To Circulation Plumbing
There are many ways to connect the flow cell tubing to the circulation plumbing. Always make sure the
input source to the flow cell is well upstream from any chemical injection points. Successful flow cell
installation requires a pressure differential, or there will be no water flowing through the cell. The Flow
cell input should be filtered water and therefore after the filter. Never install the input to the flow cell
between the main circulation pump and filter as that will be very high pressure which may damage the
sensors and provide the most debris to the flow cell. PoolWarden is equipped with a strainer to filter out
any debris that does get past the filter. Periodically check and clean the strainer. Install the flow cell
return after the heater, there will be a pressure drop across that should be sufficient to provide flow
through the flow cell. If there is no heater, the next choice is the suction plug in the pumps strainer, make
sure to adjust the return valve on the flow cell to keep the pressure in the flow cell positive.
tFlow Cell Input: Drill & tap a connection point in the circulation system at a location just after the filter.
The best location is where there is a pipe fitting as that will provide the most threads. Install a tube
connector and run tubing to the input side of the flow cell.
tFlow Cell Output: Drill & tap a connection point in the circulation system at a location with reduced
pressure just after the heater. Install a tube connector and run tubing to the return side of the flow
cell.
CAUTION: Maximum pressure across the sensors should be 10 PSI (pressure gauge may be required).
Always expose the sensors to positive pressure. Prevent exposing the sensors to suction or a vacuum
by connecting the flow cell output tubing to the suction side of the pump as the vacuum may suck the
sensor gel from the sensors rendering the sensors inoperable in a very short period of time.
tIf not pre-mounted, find a suitable location to mount the acrylic flow cell within 3 feet of the controller.
Mount and assemble flow cell parts according to the following figures. If the TrueDPD is being
installed there will be a few additional fittings for the flow cell to connect to the TrueDPD inlet.
Remove pH (Blue) and ORP (Red) sensors from the boxes. Use Teflon tape on sensor threads and
all other flow cell parts to ensure water tight connection and fasten accordingly. REMOVE THE
SENSOR GUARDS FROM THE SENSORS!
tInstall the appropriate 1/2” or 3/8” hard vinyl input and output tubing from the pools circulation system
connection points to the “In” and “Out” connection points on the flow cell.
tOnce connected, turn circulating pump back on, test for leaks at all connection points, and make sure
all air evacuates form the tubing.

tThere is a small magnet in the flow cell that is held in place with a piece of tape. Remove the tape and
make sure the magnet remains in the hole above the filter / strainer. If using a digital flow sensor the
magnet will not be needed.
IMPORTANT NOTE: There needs to be enough flow (0.5 gpm) through the flow cell to raise the flow
magnet inside the flow cell to make contact with the flow sensor. To test this, turn the “input” shut-off valve
to the off position and watch the flow magnet drop from the flow sensor. Next, turn the input shut-off valve
back on and watch the flow magnet rise to the flow
sensor. If the flow magnet rises abruptly and
pings/knocks the flow cell acrylic then the flow is
too high. To reduce flow, perform the same
exercise, but now open the shut-off valve slowly
and stop when you see the magnet “slowly” rise to
make connection with the flow sensor. Leave the
shut-off valve in that position.
Sensor Wire Connection
If not pre-mounted, route the pH (Blue Sensor
Wires), ORP (Red Sensor Wires), flow sensor and
temp sensor wires through the cable grips at the
bottom of controller and connect as labeled inside
the controller. Note: Black wires are always
negative (-) and the Clear or Red wires are
always positive (+).
REQUIRED Flow Sensor Connections:
Connect flow sensor wires for pool #1 to flow
tOptional Flow Sensor Connections: Flow switch
2 & 4 are auxiliary switches for Pool #1 and Pool
#2 respectively. For powered 3 wire digital flow
meters or water level indicators use the 18VDC
connection on the left of the main board, note
that it has a 1 amp fuse.
Supply 110/240 Vac Input Selection
The PoolWarden supports both 110 VAC and 240 VAC. For 110 VAC the power cord includes a GFCI on
the end of the cord that plugs in. For 240 VAC the cord should be removed and the PoolWarden should be
hardwired to a circuit breaker with a GFCI by a licensed electrician. The cord can be returned to
ControlOMatic for a credit.
tVAC Selector: The red switch in the center of the bottom circuit board must have the switch notch up
for 110 VAC, and down for 240 VAC. Incorrect selection will damage the PoolWarden.
tA good solid earth ground is required for PoolWarden to work properly. Without a solid ground
connection the sensors may drift.
tThe ORP and pH relay are directly connected to the input VAC. If you have the PoolWarden set for 240
VAC then the loads must also be 240 VAC.
For 240 VAC operation, the neutral line will be connected to the Red 240 VAC wire and the Line
connection will be to the Black 240 VAC wire. The Neutral connection for pH and ORP relays switches
the Neutral input VAC wire. The relays are double pole double throw and break both lines.

PoolWarden Manual • www.poolwardentraining.com • 530-205-4520 • 12
Load / Equipment Connection & Installation
ORP & pH RELAYS: The chemical feed relays for pH and ORP are internally connected to the input VAC
main input which is located on the right side connector on the circuit board through 10 AMP fuses F1 and
F2. No voltage is being supplied to the load / equipment when the relay is off, hence, voltage is being
supplied to the load / equipment when the relay is on. Any standard chemical feed pump or solenoid can
be hard wired directly into the appropriate ORP and pH connection terminals as shown below in
PICTURE 4 so long as their voltage matches the input VAC connected to the PoolWarden.
Note: Minimum wire gauge for output relays is 16 gauge.
tVACBLK: Connection to the VAC black (Line) wire
tVACWHT: For 110 VAC connect to the input white neutral wire. For 240 VAC connect to the red VAC
wire.
tPH / ORP WHT: For 110 connect to the white neutral wire on the load. For 240 connect to one of the
Line connections.
tPH / ORP BLK: For 110 connect to the black line wire on the load. For 240 connect to the other Line
connection.
tPH / ORP GND ( ): Connect to the green ground wire on the load.
DRY CONTACT RELAYS: A dry contact relay is not connected to any voltage and acts as a switch. To
supply power to a load / equipment (such as a chemical pump) through any of the auxiliary dry contact
relays, the voltage must be supplied using a jumper to the main input voltage. To facilitate this jump,
PoolWarden is equipped with terminals right next to the auxiliary dry contact relay terminals labeled
VACBLK, VACWHT and GROUND ( ). Please note that these VAC terminals are after the 10 AMP
fuses F1 and F2.
Relay Board Acronyms for the Auxiliary Dry Contact Relays:
tAUX#NO1: Normally Open aux relay, side 1 of the relay
tAUX#NO2: Normally Open aux relay, side 2 of the relay
tAUX#C1: Common connection to relay # side 1.
tAUX#C2: Common connection to relay # side 2.
tGROUND ( ): Connected to the GROUND connection on the input VAC terminal.

PoolWarden Manual • www.poolwardentraining.com • 530-205-4520 • 13
tVACBLK: A convenient connection to the input VAC black line wire.
tVACWHT: A convenient connection to the input VAC white neutral wire.
tGROUND: A convenient connection to the green ground wire.
t
Supported Auxiliary Dry Contact Loads/Equipment:
tStandard Chemical Feed Pumps: Any Chemical Feed Pump can be connected to an Auxiliary Dry
Contact Relay as shown in PICTURE 4 on the previous page. This may be needed to set up a back up
sanitizer to the main sanitation control. A black wire 110 VAC jumper is needed to energize the dry
contact for 110 VAC operation and two jumpers for 240 VAC operation..
tChlorine Generators: A high power chlorine generator should not be powered using PoolWarden’s
internal power as it may exceed the input 2.5 AMP relay rating. Simply connect an auxiliary dry contact
to control the on/off status of the generator. When PoolWarden’s relay turns on, while the flow switch is
on, then the chlorine generator will turn on. When the relay is turned off it makes the chlorine generator
think there is no flow, and the chlorine generator will turn off.
tLoads / Equipment Using External 24 VAC (Erosion Feeders & Suction Side Cal Hypo): Solenoids are
used to control water flow through a chlorine erosion feeders and suction side cal hypo systems and
most use 24 VAC. Install a 24 VAC Transformer external to the PoolWarden and connect one of the
output leads to an AUX#C1 relay and connect the AUX DRY#NO1 to the solenoid as shown in
PICTURE 5. Connect the other 24 VAC Transformer wire to the remaining solenoid wire (C). If the 24
VAC Transformer has a an output ground wire then connect it to one of the Ground terminals on the
relay board.
tCirculation Pumps: Never connect a circulation pump directly to any of the relays inside PoolWarden.
Always use an external High-Power Relay that the Auxiliary Dry Contact Relay inside PoolWarden can
control. Please refer to the circulation pump’s manual for proper set-up and control of a variable speed
pump.
tExternal Alarms (Light or Sound): If a more noticeable alarm notification is needed beyond the red LED
on PoolWarden’s front panel, a relay can be set up to output the alarm status to an external buzzer or
light.

PoolWarden Manual • www.poolwardentraining.com • 530-205-4520 • 15
The TrueDPD is an optional accessory that adds a free chlorine measurement. The measurement uses
the DPD method and is not affected by pH, cyanuric acid, saltwater chlorine generators or any other
variables that affect an ORP or amperiometric measurement. It interfaces with the controller using one of
the existing flow switch inputs.
Mounting: Locate a vertical section of wall space close enough to the controller so that the interface
cable can reach the controller. Attach to the wall with 4 screws. The TrueDPD must be located close to the
flow cell for the tube to reach.
When making a measurement, water will flow through the supply tube for about 20 seconds and for fresh
water to reach the sample chamber the supply tube must be as short as possible. Water from the
TrueDPD goes to the drain and does not continuously flow to keep the water fresh. With higher sample
times, the water in the tube will be less representative of the pool water as time goes on until the next
measurement.
Drain: Attach 1/2” tubing to the drain connection on the front of the measuring cell. The tube needs to be
routed through the cable grip near the front bottom center of the box. The tube end should be routed to a
waste drain that is lower than the TrueDPD and should have no obstructions. If there is no drain then a
bucket can be used but it will need to be emptied a couple times a week.
Water In: Attach a 1/4” “T” to the exit of the flow cell before the shut off valve. Attach the 1/4” NPT to barb
into the “T”. Route the inlet tube from the TrueDPD and attach to the barb. WARNING: If the pressure is
too high the tube may pop off of the barb fitting. The tube has a barb fitting on the flow cell and
inside the TrueDPD enclosure at the small pump. If inside the TrueDPD damage will occur to the
motors and circuitry.
nPool1 (PPM1) uses the lower pump on the left and Pool2 (PPM2) uses the pump on the right.
PoolWarden Interface: Connect the red interface wire to the Flow4 input on the PoolWarden display
board and the black wire to GND.
Power Supply: Plug the power supply into the power source. The power supply also supports 240 VAC.
If power source is 240 VAC then a suitable plug adapter may be needed. If there is no outlet, a short
extension cord can be used inside the controller enclosure allowing the 12V power supply to reside inside
the enclosure where it has additional protection.
