• For runs of under 30 feet (9 m), remote wiring should
have stranded conductors with a minimum of 22
AWG, 600V, cable twisting 1.5" to 2.5" (3.8 to 6.4 cm)
lay and jacketed.
• For runs over 30 feet (9 m), the conductors should be
a minimum of 20 AWG, 600V, cable twisting 1.5" to
2.5" (3.8 to 6.4 cm) lay that is shielded and jacketed.
• Maximum cable length recommended is 200 feet
(61 m).
• For both two- and three-wire remote systems, the
provided 3-pin REMOTE connector "P7" must be
utilized.
NOTE: The remote wires must be connected to the
3-wire remote interface harness before the connector is
plugged into the board.

Figure 56. 3-Wire Remote Harness
2-Wire Remote Control (On-Off)
This application assumes that only one heating function
(pool or spa) is required.
1. Turn on power to the heater.
2. For a remote controller without its own thermostat,
push the MODE key to the “POOL” or “SPA” mode and
set the desired setpoint (e.g.102°F (39°C) for spa).
3. For a remote controller with its own thermostat, push
the MODE key to select “POOL” or “SPA” mode and
set the temperature to the highest setting available on
the control. The actual setpoint will be controlled by
the remote controller.
4. Turn the MODE button to "OFF" and remove power
from the heater.
5. On the 3-wire remote harness, connect the BLUE wire
to one side of the remote automation controller and
connect the other side to either the ORANGE/BLACK
wire for “SPA” operation or the BLACK/ORANGE wire
for “POOL” operation. See Figure 57.
6. Attach wire nut on the unused wire of the harness.
7. Install the “3-wire Remote Harness” to the "P7"
connector and turn power "ON" to the heater. See
Figure 57.
8. Activate remote mode in the heater. Press and hold
the UP and DOWN arrow keys simultaneously for 3 to
5-seconds.

This application assumes that both heating functions (pool
and spa) are required.
1. Turn on power to the heater.
2. For remote controllers without its own thermostat,
push the MODE key to the “POOL” or “SPA” mode
and set the desired temperature for each, e.g. 80°F
(27°C) for Pool and 102°F (39°C) for spa.
3. For remote controller with its own thermostat , push
the MODE key to select “POOL” or “SPA” mode and
set both temperature setpoints to the highest setting
available on the heater. The actual setpoint will be
controlled by the remote controller.
4. Turn the MODE key to "OFF" and remove power from
the heater.
5. On the 3-wire remote interface harness, connect
the BLUE wire to one side of the remote automation
controller and connect the ORANGE/BLACK wire for
“SPA” operation and the BLACK/ORANGE wire for
the “POOL” operation. See Figure 58.
6. Install the 3-wire remote interface harness to the
"P7" connector and turn power ON to the heater. See
Figure 58.
