• If you are using a Jandy AquaSwitch or JI2000 control run a 3 wire cable from the control to the
heater. Remove the 6 screws from the heaters front service access panel and open. Look for the
heater's solid state circuit board located inside the top portion of the electrical compartment mounted
on the rear wall. Locate the 3 terminals labeled POOL SPA SWITCH. Attach the 3 wire cable as
shown below. Do not remove any jumpers. Run the wire through the heater's low voltage access
port.

Heat pumps require a relay kit (Model RLY-LX) be added. The HTR connection used for gas
heaters cannot be used.
To wire a heat pump:
1. At the Power Center, install the relay into the high voltage compartment. Plug control wire
into the EHTR relay socket on the Power Center circuit board.
2. Run a 2-conductor cable from the heater to the Power Center,
3 At the heater, remove jumper and connect 2-conductor cable to the terminals.
4. At the Power Center, connect 2-conductor cable to LINE 1 and LOAD 1of the relay terminal
block.
5. Turn thermostat settings all the way up on the heat pump.
