2-Wire Remote Control (On-O)
This application assumes that only one heating function
(pool or spa) is required.
1. Turn on power to the heater.
2. For a 2-Wire Remote Control from a remote controller
without its own sensor, 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 2-Wire Remote Control from a remote controller
with its own sensor, 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 “Remote Interface Harness”, connect the
BLUE wire to one side of the “REMOTE” switch 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 to the “Remote
Interface Harness.”
7. Install the “3-wire Remote Control Harness” to the P8
connector and turn power "ON" to the heater. See
Figure 57.

3. Turn the MODE key to "OFF" and remove power from
the heater.
4. On the 3-wire “Remote Interface Harness” connect
the BLUE wire to one side of the “REMOTE” switch
and connect the ORANGE/BLACK wire for “SPA”
operation and the BLACK/ORANGE wire for the
“POOL” operation. See Figure 57.
5. Install the 3-wire “Remote Interface Harness” to the
P8 connector and turn power ON to the heater. See
