REMOTE CONTROL CONNECTION:
The heater is equipped for con-
nection to an external 2-wire remote
thermostat or a 3-wire remote switch. A
2-wire thermostat has its own tempera-
ture sensor for regulating water tempera-
ture. A 3- wire remote switch allows the
“POOL” or “SPA” models to be re-
motely selected. Connect remote wiring
to the terminal block located in the lower
compartment inside the junction box (see
Figure 22). The heater has 2 junction
boxes (one on each side of the heater).
Only one junction box should be used for
remote wiring. Do not remove the wires
connected to the remote connection ter-
minal block. Remote wiring must be run
in a separate conduit. Use 22 AWG wire
for runs less than 30 feet. Use 20 AWG
wire for runs over 30 feet. The maximum
allowable run is 200 feet.

2-WIRE REMOTE CONTROL CONNECTION:
To congure the heater for 2- wire remote thermostat control, use the “MODE” key on the heater keypad
to put the control into “STANDBY” mode. Then press and hold both the “DOWN” and “MODE” keys for 3
seconds until the display shows the code “bo”.
On the remote control wiring terminal block (Figure 22), connect the appropriate wires from the remote
control to the terminals adjacent to the ORANGE wire (“POOL”) and WHITE wire (“24V”).
To operate the heater by remote thermostat, the heater’s control must be in either “POOL” or “SPA”
mode. The display will show “bo”. The “POOL” or “SPA” LED will be illuminated. The remote thermostat
will operate the heater. The heater’s thermostat will function to limit the water temperature to a maximum of
104°F.
3-WIRE REMOTE CONTROL CONNECTION:
On the remote control wiring terminal block (Figure 22), connect the appropriate wires from the remote
control to the terminals adjacent to the ORANGE wire (“POOL”), WHITE wire (“24V”), and RED wire
(“SPA”). To operate the heater with a remote 3-wire switch, the heater’s control must be in “STANDBY”
mode. The “STANDBY” LED will be illuminated. When the remote switch is set to “Pool/Low” the “POOL”
LED will be illuminated and the water temperature will be displayed. When the remote switch is set to “Spa/
High” the “SPA” LED will be illuminated and the water temperature will be displayed. The heater will use its
internal thermostat to regulate the water temperature to the set point of the mode selected.
