HEATER CONNECTIONS

DUAL THERMOSTAT GAS HEATER/HEAT PUMP

Inside the heater, connect three 18 AWG wires in parallel with the heater toggle switch or in accordance with the Heater Manufacturer’s instructions.

Do not disconnect or bypass the flow, pressure or high limit switches.

Place the heater toggle switch in the “OFF” position, and set the thermostats to desired pool and spa temperatures.

Run the three wires to low-voltage compartment of LX-100 RF Power/Load Center.

Strip insulation ¼”, and connect to circuit board at GHTR Screw Terminals, in accordance with wiring diagram located inside the LX-100 RF Power/Load Center cover:

Connect “High” of heater thermostat to Terminal #S. Connect “Low” of heater thermostat to Terminal #P. Connect “Common” of heater thermostat to Terminal #C.

SINGLE THERMOSTAT GAS HEATER/HEAT PUMP

Inside the heater, connect two 18 AWG wires in series with the heater circuitry.

Do not disconnect or bypass the flow, pressure or high limit switches.

Place the heater toggle switch in the “ON” position, and set the thermostat to the desired temperature.

Run the two wires to low-voltage compartment of LX-100 RF Power/Load Center.

Strip insulation ¼”, and connect to GHTR Screw Terminals at Terminals #P and #C.

Make a jumper wire and connect Terminals #P and #S together.

ELECTRIC HEATER

For systems which utilize an electric heater, a 20-Amp Relay Kit (model RLYLX) should be added at the LX-100 RF Power/Load Center.

Install RL-LX in accordance with instructions provided, and plug onto circuit board at the EHTR relay socket.

The relay is capable of controlling an electric heater (rated up to 3KVA), or the magnetic contactor of a larger electric heater.

Inside the heater , connect two 14 AWG wires in series with the heater thermostat circuitry. Place the heater toggle switch in the “ON” position, and set the thermostat to the desired temperature.

Run the two wires to the high-voltage compartment of the LX-100 RF Power/Load Center, and connect to LINE1 and LOAD1 terminals of the electric heater relay.
