DIGITAL THERMOSTAT CONTROLS
Thermostat operation
Your heater is equipped with a microprocessor-controlled thermostat that controls the pool or spa temperature by measuring the temperature of the water entering the heater. It monitors the water temperature and turns the heater on when it
senses that the water temperature is below the set point. It is normal to experience small fluctuations in the return water
temperature during the operation of the heater. The thermostat is calibrated with a very narrow tolerance to ensure accuracy of the set temperature. Thus, slight fluctuations in water temperature may cause your heater to cycle on and
off frequently. This is not a problem. It will not harm the heater nor interfere with the thermostatʼs ability to precisely control the temperature of the pool or spa.

THERMOSTAT CONTROL OPERATION
The pool heater thermostat, located on the upper front panel
of the heater, controls the pool/spa water temperature. This
control center contains a mode button, up and down temperature adjustment buttons, and an LCD display.
Mode Button
The MODE button functions as a means to turn the heater off
or on in either the POOL or SPA setting. The LCD display indicates the mode the heater is in and the actual water temperature.
Temp Buttons
If the heater is in POOL or SPA mode, the desired water temperature (SETPOINT) will also be displayed and may be
changed using the UP or DOWN buttons. A manual toggle
switch is also provided right below the MODE button to allow
the heater to be turned off.
Operation
In the POOL or SPA modes, the actual water temperature is
displayed along with the desired water temperature (SETPOINT). If the heater is firing, a flame icon will be visible.
To adjust the setpoint temperature, make sure the control is
in the appropriate mode (POOL or SPA) and push the UP or
DOWN buttons.

NOTE: The LCD temperature display may not agree with the temperature reading of your pool or spa thermometer. The
heater reads the water temperature at the inlet. Due to the circulation characteristics of any pool or spa, the water temperature at the inlet to the heater may differ from that observed at a given location in the pool or spa.
DIAGNOSTICS
The digital thermostat models are equipped with on-board
diagnostic controls. If there is a safety fault, a fault code will
be displayed along with a service indication.
If the PRS fault code is displayed, it indicates that there is
insufficient water flow through the heater. Make sure the
pool filter and pump strainer are clean before calling a service representative.

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 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 REM 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.

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.
For operation of the heater using the onboard thermostatic
controls with a time clock, see the “Time Clock / Firemanʼs
Switch” section.
The digital display format will change and indicate REMoFF
or REMOn.
REMOn = External remote control active (display will flash REM)
REMoFF = Remote disabled (heater
thermostat will control heater - use this
mode to test heater operation)
NOTE: When in remote operation, the keypad mode and
temp buttons are disabled. Remote will flash even when
the unit is off.
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 accumulates on the body. Contact of
a finger allows the body to discharge, 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 enclosure for 5 seconds before proceeding.
