Pentair Pool Products MiniMax 250 Operating & Installation Manual page 9

Installation (Remotes)
TWO-WIRE OR THREE-WIRE REMOTE HOOK-UP, (cont'd.)
• Three-wire remote:
a) Using 3/16" female quick disconnect connectors, connect the common wire to the "GND" tab of the
temperature controller, then connect the two remaining wires to the temperature controller
corresponding to the remote control device, pool wire to "POOL" tab, spa wire to "SPA" tab.
b) Now return power to the heater. (Note: If you used the main power switch to turn off the heater, now
turn the main power switch on.) At this time, the remote system has control over the heater and if pool
or spa temperature is below the temperature controller setting, then the heater will try to come on.
c) If you desire to reset the temperature settings of the temperature controller, the remote has to be in the
desired mode for you to change the particular setting. Example: You wish to raise or lower the pool
temperature from the factory setting, you must have the remote system in the pool mode, if you wish to
change the spa temperature, you must have the remote system in the spa mode.
5. Now turn on the gas valve to "OPEN" position, the heater is now ready to
operate.
The heater factory settings are 78° F. for the pool and 104° F. for the spa.
When connecting a remote control to the MiniMax, you must install the low
voltage thermostat wires in separate conduit from ANY line voltage wires.
Failure to follow these instructions will cause the thermostat relay to react
erratically. A Remote hook-up deactivates the selector keys on the front
thermostat display panel and gives selection control to the remote.
