"Zone Control Blocks"
Your new controller has six (6) "Zone Control Blocks". Each "Zone Control Block" contains the necessary switches
and lights to control the misting operation for that zone. Each "Zone Control Block" contains the following three (3)
items: 1) a "Zone On Indicator (LED lamp)"; 2) a "Seconds of On Time" rotary switch; and 3) a "Minutes Between
Cycle" rotary switch. e operation of each of these zone controls is described in detail below.
"Zone On Indicator (LED Lamp)"
e "Zone On Indicator" is a light located at the top of each "Zone Control Block" on your new controller. e light
is an indication that 24VAC power is being delivered to the zone’s valve.
"Seconds of On Time"
e "Seconds of On Time" switch is located in the top portion of the "Zone Control Block". Rotating the selector
switch clockwise will increase the amount of time during which 24VAC output power will be delivered to the appro-
priate valve. Rotating the selector switch counter-clockwise will decrease the amount of time. "Seconds of On Cycle"
selections for the NOVA controller are listed below:
Time Extender Available Selections (Seconds)
1X 2, 4, 6, 8, 10, 12, 15, and 20
2X 4, 8, 12, 16, 20, 24, 30, and 40
3X 6, 12, 18, 24, 30, 36, 45, and 60
"Minutes Between Cycle"
e "Minutes Between Cycle" switch is located at the bottom of each "Zone Control Block". Rotating the selector
switch clockwise will increase the amount of time between the start of each "On" cycle
when 24VAC power is delivered to the appropriate valve. Rotating the selector switch counter-clockwise will decrease
the amount of time. e "OFF" position will prohibit any valve operation; while the “ON” position will force the valve
into continuous operation. e "ON" and "OFF" positions are considered manual operations. "Minutes Between
Cycle" selections for the controller are listed below:
Time Extender Available Selections (Minutes)
1X ON, 2, 4, 6, 10, 15, 30, 60, and OFF
2X ON, 4, 8, 12, 20, 30, 60, 120, and OFF
3X ON, 6, 12, 18, 30, 45, 90, 180, and OFF
"Power Switch"
e "Power" switch turns on and o all power to the controller. Safety requirements dictate that the unit be turned
"O" when the unit is being installed or serviced, or when valves are being attached to or removed from the controller.
Self-Resettable Internal Fuse
Each controller is supplied with a 2 AMP self-resettable internal fuse to prevent damage to the internal circuits as well
as to valve wiring and low wattage solenoid valves. e fuse will interrupt all internal power to the controller and the
24VAC power to the valves. Should the 'short circuit' still exist, the fuse will again trip and interrupt service.
Understanding Your Controller

2
Manufacturer’s Note: Whenever the fuse 'trips' it is recommended that all valves and valve wiring be
inspected for 'short circuits'. Excessive tripping of the fuse will shorten its lifetime, requiring factory service and
grower loss of use. Short circuits may be caused by crossed wiring, improper grounding techniques, damaged
valves, moisture collection, or an internal controller malfunction.
"Time Extender Block”
Equipped with an additional feature; the "Time Extender". e "Time Extender" is a three (3) position toggle
switch which will multiply the "Seconds of On Time" and "Minutes Between Cycle" times by one (1X), two
(2X), or three (3X), depending on switch position. Selection of the 1X position indicates that the "Seconds of
On Cycle" and "Minutes Between Cycle" periods will be as they are marked. Selection of the 2X position of
the "Time Extender" will double all time periods, and selection of 3X will triple the time periods.
Example #1: With the "Time Extender" set for 3X operation:
Function Knob Setting Position wActual
Time
"Seconds of On Time" 20 seconds 60 Seconds
"Minutes Between Cycle" 60 minutes 180 Minutes
NOTE: Controllers have water-tight, easy-turn switches to endure many years of continued use. Each switch
has a xed stop position at the minimum and maximum selectable time. DO NOT force the
switches past the minimum or maximum times available for your model.
Installing Your Controller
We would highly recommend using a surge protector when operating your misting controller; so it will stop voltage
spikes and surges that could damage your controller, such damage is not covered by your warranty.
CONTROLLER LOCATION:
Selecting the proper location for mounting your new controller is important, and there are several guidelines
you should follow to insure long and satisfying service.
1) HEAT: Avoid locations of excessive heat, such as extended exposure to direct sunlight and locations near
heaters or boilers.
2) LIQUIDS: Select a location where the controller is away from direct and continuous ooding from liquids.
When water is sprayed on the controller, the water will get inside and on the circuit board shorting it out. is
will cause damage not covered by the warranty.
3) POWER: 24V plug in transformer supplied.
CONTROLLER MOUNTING: Your new controller is supplied with all necessary mounting hardware for
a typical installation. For hollow-wall or concrete mounting surfaces, additional hardware may be required to
secure the controller properly. Pre-drill the marked locations with a 1/8” or smaller starter hole. Install the two
(2) bottom mounting screws, leaving approximately 1/16” between the head of the screw and the mounting
surface. Test t the controller by inserting the bottom mounting holes over the head of the mounting screws.
Loosen or tighten the mounting screws as required, to provide a snug- t between the controller and mounting
surface.
Starting Your Controller
After you have selected and mounted your controller, and wired the solenoid valves, you are ready to begin
misting operations. Improper grounding will void the warranty of the controller. Do Not connect solenoid
valves to the controller before verication and trial operation.
Connecting the 24VAC Power Plug:
Be sure the controller power switch is in the “o” position. Plug into connector. Ensure the power cord is
routed away from walkways and high trac areas to prevent accidental interruption of power to the controller.

SETTING OR CHANGING THE TIME
*Note* When setting the clock the screen will actually go through the event programming rst. PRESS &
HOLD ENTER • e display will rst switch to EVENT programming after 2-3 seconds and then to the
TIME programming mode after 4-5 seconds.
• Use the UP or DOWN buttons to set time. NOTE: A red dot will appear on the lower right digit
display indicating PM.
• To nish setting time, press ENTER
TO SET OR CHANGE PROGRAMS
Events are for turning the controller on and o. For example EVENT 1 can be set for ON at 8am and
OFF at 5pm, to run the controller during the day. EVENTS 2 through 8 can be set to turn the controller
on at multiple times during the night.
Events cannot control single zones, only turn all of of the zones on and o.
• ere can be up to 8 events (on-o functions) that can be programmed.
• Press & hold the ENTER key for 2-3 Seconds. • Event 1 will rst appear indicating “ON”.
• Pressing the UP or DOWN key will begin the time setting.
• Press the ENTER key again to program the “OFF” time and use the UP or DOWN key to set the
time.
• Press ENTER to move to the next Event. To end programming, press ENTER until it passed Event
8. It will go back to run mode.
• If ON/OFF times have been entered, those times will be shown and can be changed if needed, or
bypassed to setting or reviewing the following programs. NOTE: A red dot will appear on the lower
right digit display indicating PM.
NOTE: Events are not needed for controller to work. e controller will run 24 hours with no pro-
grams.

CONNECTING YOUR SOLENOID
• Standard 24VAC Solenoids
• Simply strip wire jacket back approximately ¼” from end of both wires,
(if not already done by manufacturer).
• e controller powers AC solenoids (common solenoids used for lawn irrigation) ere is no
hot or neutral wire. Tie one wire from all the solenoids together and insert wire into #1 slot of
solenoid plug (provided by Phytotronics) and the other wires into the #2 through #7 slots and
tighten down rmly, BY HAND, with supplied Phytotronics screwdriver.
• 3 Wire 24VAC Solenoids
• Attach the 2 power wires just like a 2 wire solenoid into solenoid plug.
• e 3rd wire is a ground wire. (usually green or green with a yellow stripe)
ground this wire properly with all local, state, and national codes.
• 120VAC solenoids will not work directly with your
Nova.
•You must use some kind of 24VAC interface between your
Nova and 120VAC solenoid. i.e. a 24VAC relay.
NOTE: Any attempt to bypass the 24VAC transformer to power this unit directly from a 120VAC
power source will damage the controller’s circuitry and render it unt for use. Such action will also
void the Phytotronics warranty!
NOTE: Maximum controller output is 1 Amp at one time. If output is exceded, CR ERR will appear
on the display. Turn the unit o, x the condition and turn back on. is should clear the error.
