8.4.1. Remote Control Installation and
Operation
CAUTION: Before installing remote controls to the
A
heaters, read the following: The digital thermostat
model is remote-ready in most cases. The digital liquid
crystal display (LCD) shows the actual pool temperature,
operating status, and service codes. See Figure 41. The
touch pad on the control panel allows you to select the
desired pool or spa temperature. It also indicates when
a remote system is controlling the heater by displaying
Remote in the display. When connecting the heater to a
remote system, identify whether it is a two- or three-wire
remote system. Select the appropriate instruction listed
below to properly install the remote to the heater.
8.4.2. Remote Operation
The heaters are equipped with the ability to work with
external remote controls. The supplied 7-pin remote wiring
connector supplies power out to either a toggle switch or
the switch contacts of a third party remote. The remote
works by either making or breaking the circuit created
by the remote wiring. Typically, a remote does not supply
power to the heater, it only provides a switching function
to turn the heater On or Off. If your remote is supplying
its own voltage to the heater, it will not work with this
heater and may damage the digital circuit board. For
operation of the heater using the onboard thermostatic
controls with a time clock.
