Pentair/Purex/MiniMax
1. Turn power off to heater.
2. Remove factory installed jumper from the “Ext Switch” connector.
3. Wire the OnCommand to the “Ext Switch” connector as shown below.
4. The wires to the OnCommand must be separated from any line voltage wires. Failure to follow these
instructions may cause erratic operation of the heater.
5. Set the Power (Thermostat Select) switch to either “Pool” or “Spa”.
6. Set the “Pool” and “Spa” thermostats to their maximum settings.
Raypak RP2100 Pool/Spa Heater
1. Turn power off to heater.
2. Push the mode button to “spa” mode.
3. Set the temperature to the maximum.
4. Push the mode button to “OFF”.
5. Lastly, plug the prewired connector in the P7 position on the board.
!
IMPORTANT: The heater will display “OFF” when it is being remotely controlled by the
OnCommand. Some homeowners see the “OFF” display and, thinking this is a mistake, change the
mode to “POOL” or “SPA” which then disables the remote control by the OnCommand. To prevent
this: Remove the heater touch pad connector (P5) which will disable the touchpad.

Filter Pump
For 2-speed pumps: When a 2-speed pump is configured, one of the AUX relays must also be
configured to control the low speed motor winding on the pump. Refer to the appropriate sections in
the Installation manual for specific information regarding the control logic for 2-speed and variable
speed pump operation.
For the Hayward Tristar variable speed pump: The Filter relay is used to supply input power to the
VSC pump control. The relay will be on when the filter pump output is on. When the filter pump
output is off, the relay will be off. On , off and speed is controlled by commands sent to the pump.
Lowest Speed
This is the lowest speed that the variable speed pump is allowed to run at. It is used as the lower limit
in the Low Speed Settings Menu. Set lowest speed from 10% (default) to 50%.
Highest Speed
This is the highest speed that the variable speed pump is allowed to run at. It is used as the upper limit
in the High Speed Settings Menu. Also, this is the speed that the pump will run at during the first 3
minutes of operation anytime the pump has been off for more than 30 seconds. Set highest speed from
20% to 100% (default).
Freeze Protection
Freeze protection is used to protect the pool and plumbed equipment against freeze damage. If freeze
protection is enabled and the AIR temperature sensor falls below the freeze threshold (see below), the
OnCommand will turn on the filter pump to circulate the water. If “Pool and Spa” is selected in the Pool/
Spa sub-menu, the valves will also alternate between the pool and spa every 30 minutes and the filter
pump will turn off while the valves are turning. The chlorinator will not operate if freeze protection is
the only reason the pump is running.
Freeze Protection Speed
This menu only appears if freeze protection is enabled and the pump is configured for 2-speed or
variable speed pump operation. This is the speed that the pump will run at during freeze protection
operation. Select high (default) or low speed operation.
Freeze Protection Temperature
Select the temperature to be used for freeze protection. Temperature is adjustable from 33ºF - 42ºF
(1ºC - 6ºC). 38ºF (3ºC) is default. This threshold will be used for all outputs that have freeze protection
enabled.
