REMOTE CONTROL INSTALLATION AND OPERATION
CAUTION: Before installing remote controls to the digital thermostat model 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 examples below). The touch pad on the con-
trol panel allows you to select the desired pool or spa temperature. It also indicates when a remote system is
controlling the heater by displaying REM in the display. When connecting the heater to a remote system, iden-
tify whether it is a two- or three-wire remote system. Select the appropriate instruction listed below to properly
install the remote to the heater.

REMOTE OPERATION
The digital model 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 suppling its own
voltage to the heater, it will not work with this
heater and may damage the digital circuit board.
ACTIVATING THE REMOTE
The digital thermostat heaters have the ability to dis-
connect from the remote it is wired to. To activate or
deactivate the remote follow these steps:
Note: Electrostatic Discharge (ESD) damage can be caused by
direct or indirect contact with the wiring or circuit board. When
one walks to the heater area, an electrostatic charge accumu-
lates on the body. Contact of a finger allows the body to dis-
charge, possibly causing device damage. This damage can be
limited if the service person discharges himself, following ESD
preventive/removal practices, and holds on to the heater enclo-
sure for 5 seconds before proceeding.
