REMOTE CONTROL WIRING Important Installation Notes for Remote or External Wiring Configuration • Remote wiring must be run in a separate conduit. • Remote wiring must not be run parallel to high voltage lines. • For runs of under 30 feet, remote wiring should have stranded conductors with a minimum of 22 AWG, 600V, cable twisting 1.5 to 2.5 in. lay and jacketed. • For runs over 30 feet, the conductors should be a minimum of 20 AWG, 600V, cable twisting 1.5 to 2.5 inch lay that is shielded and jacketed. • Maximum cable length is 200 feet. • For both two- and three-wire remote systems, the provided 7-pin wiring connector must be utilized. Please refer to the wiring instructions. NOTE: The remote wires must be connected to the 7-pin connector before the connector is plugged into the board. 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 2-Wire Remote Control from a remote without its own sensor, push the mode button to the "POOL" or "SPA" mode and set the desired setpoint (eg. 102 °F for Spa). 3. For a 2-Wire Remote Control from a remote with its own sensor, push the mode button "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 control. 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. 6. Attach wire nut on unused wire to the "Remote Interface Harness." 7. Install the "7-Pin Remote Interface Harness" to the P8 connector and turn power "On" to the heater. To activate the remote control, see page 36. 3-Wire Remote Control Using Three-Position Switch (Pool-Off-Spa, or Low-Off-High) This application assumes that both heating functions (pool and spa) are required. 1. Turn on power to the heater. 2. Push the mode button to the "POOL" or "SPA" mode and set the desired temperature for each (eg. 80°F for Pool and 102°F for Spa). 3. Turn the mode button to "OFF" and remove power from the heater. 4. On the "Remote Interface Harness" connect the BLUE wire to one side of the "REMOTE" switch and con- nect the ORANGE/BLACK wire for "SPA" operation and the BLACK/ORANGE wire for the "POOL" operation. 5. Install the "Remote Interface Harness" to the P8 connector and turn power "ON" to the heater. To activate the remote control, see page 36.

REMOTE CONTROL WIRING
Important Installation Notes for Remote or External Wiring Configuration
•
Remote wiring must be run in a separate conduit.
•
Remote wiring must not be run parallel to high voltage lines.
•
For runs of under 30 feet, remote wiring should have stranded conductors with a minimum of 22 AWG, 600V,
cable twisting 1.5 to 2.5 in. lay and jacketed.
•
For runs over 30 feet, the conductors should be a minimum of 20 AWG, 600V, cable twisting 1.5 to 2.5 inch
lay that is shielded and jacketed.
•
Maximum cable length is 200 feet.
•
For both two- and three-wire remote systems, the provided 7-pin wiring connector must be utilized. Please
refer to the wiring instructions.
NOTE:
The remote wires must be connected to the 7-pin connector
before
the connector is plugged into the board.
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 2-Wire Remote Control from a remote without
its own sensor, push the mode button to the “POOL” or
“SPA” mode and set the desired setpoint (eg. 102 °F for Spa).
3.
For a 2-Wire Remote Control from a remote with
its own sensor, push the mode button “POOL” or “SPA”
mode and set the temperature to the highest setting available on the control. The actual setpoint will be con-
trolled by the remote control.
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 con-
nect the other side to either the ORANGE/BLACK wire for "SPA" operation or the BLACK/ORANGE wire for
"POOL" operation.
6.
Attach wire nut on unused wire to the "Remote Interface Harness."
7.
Install the "7-Pin Remote Interface Harness" to the P8 connector and turn power “On” to the heater.
To activate the remote control, see page 36.
3-Wire Remote Control Using Three-Position Switch (Pool-Off-Spa, or Low-Off-High)
This application assumes that both heating functions (pool and spa) are required.
1.
Turn on power to the heater.
2.
Push the mode button to the "POOL" or "SPA" mode and set the desired temperature for each (eg. 80°F for
Pool and 102°F for Spa).
3.
Turn the mode button to "OFF" and remove power from the heater.
4.
On the "Remote Interface Harness" connect the BLUE wire to one side of the "REMOTE" switch and con-
nect the ORANGE/BLACK wire for "SPA" operation and the BLACK/ORANGE wire for the "POOL" opera-
tion.
5.
Install the "Remote Interface Harness" to the P8 connector and turn power "ON" to the heater.
To activate the remote control, see page 36.
