TWO-WIRE OR THREE-WIRE REMOTE HOOK-UP
Installation (Remotes)
Before connecting the remote control system please read the following:
1. First turn the gas valve to the "OFF" position and power up the
heater, now using the front buttons on the temperature controller,
set the "SPA" and "POOL" temperature to the maximum setting,
see Page 24.
2. Now turn the heater to the "OFF" mode by using the "OFF" button
on the temperature controller, see Page 24 or by using the main
power switch located on the bottom of the junction box.
3. With the heater in the "OFF" mode, locate the three tabs on the back
of the temperature controller as viewed from the backside,
see Figure 6.
4. • Two-wire remote with temperature control:
a) Using 3/16" female quick disconnect connectors, connect one
wire to the "GND" tab of the temperature controller, then the
second wire to either the "SPA" or "POOL" tab.
b) Now return power to the heater but leaving the temperature controller in the "OFF" position,
see Page 24. (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 will turn it on and off when
called for by the remote system thermostat thus keep the pool and spa at the desired temperature.
