STA-RITE Heater
1. Turn power off to heater.
2. Remove upper jacket and open the control box.
3. Remove the jumper for the “fireman’s switch.
4. Wire to the OnCommand using wire rated for 105°C minimum.
Hayward Variable Speed Filter Pump:
Refer to the diagram below for proper low voltage communication
wiring between the OnCommand and the Hayward Tristar Variable Speed Control (VSC).
Use four conductor cable (typically phone cable) for communications connection between the VSC and the
OnCommand. The maximum wiring distance is 500 feet (160 meters). Note that the terminals on both the VSC
interface board and the OnCommand main board are numbered. The terminal connections should be matched
between both terminal blocks (connect 1 to 1, 2 to 2, etc.). The communications cable should be routed through
the knockout hole on the left side of the VSC enclosure, and a watertight fitting should be used to keep water and
debris out of the opening. The communications cable should also be routed away from the OnCommand and VSC
power connections if possible.

Pool/Spa Setup
If “Pool Only” or “Spa Only” are selected, then the pool/spa valves are not needed and pushing the
POOL/SPA button on the display/keypad will have no effect. If “Pool and Spa” is selected, then the
pool/spa suction and return valve actuators should be connected to the OnCommand. Pressing the
POOL/SPA button on the display/keypad will alternate between pool and spa operation.
Spa CountDn
This menu will appear only if Pool/Spa Setup is set to “Pool and Spa”. This setting is the time, after
you manually switch the Pool/Spa valves to “Spa Only”, until the OnCommand automatically returns
the valves to their previous positions. It is programmed in increments of 5 minutes, from “Manual On/
Off” (0 minutes) to “21:00” (21 hours). The filter is forced on during this time period.
Spa Spillover
When spa spillover is “Enabled” and “Pool and Spa”, the homeowner will be able to rotate through
“Pool Only” (both suction and return valves switched to pool), “Spa Only” (both suction and return
valves switched to spa) and “Spillover” (suction valve switched to pool and return valve switched to
spa) by successive presses of the “Pool/Spa button.
Filter Operation
If “Spa Spillover” is selected, the OnCommand will automatically switch the pool/spa suction and
return valves to “spillover” at the start of the programmed pool filtering time period or when the super-
chlorinate function is turned on. The valves will remain in this position for the remainder of the super-
chlorinate period. This option is usually preferable because both the pool and spa water will be
filtered and sanitized.
If “Pool Only” is selected, then the OnCommand will switch the pool/spa valves to the “pool only”
position at the start of the programmed pool filtering time period or when the super-chlorinate function
is turned on. This may be desirable on some systems with in-floor cleaners because it allows the
cleaner to operate all the time the pool is being filtered and/or the super chlorinate is running.
V1=Aux1, V2=Aux2
This menu appears only if the Pool/Spa Setup is “Pool Only” or “Spa Only”. When enabled, Valve 1
(return) will follow the Aux1 output and Valve 2 (suction) will follow the Aux2 output. When disabled
(default), the return and suction pool/spa valves function normally.
Filter Off Valve Change
This menu appears only if Pool/Spa setup is set to “Pool and Spa - Std”. When enabled (default), the
filter pump will shut off for 35 seconds whenever the Pool/Spa valves are turning. The pump will NOT
shut off when a heater is in Heater Cooldown mode.
