Changing the Set Point (Temperature)
The control board has two independently adjustable

control and the other is for the spa temperature control.
The active mode of operation (Pool or Spa) is defined
as the “active” set point.
1. Press the MENU SELECT button repeatedly until
the associated run screen is displayed. Press the
UP or DOWN arrows to adjust the pool or spa
temperature set point.
SET= ___ - Set point

2. The screen automatically returns to the active run
screen after 15 seconds of keypad inactivity.
Efficiency Mode Selection
These heaters can be setup to operate in any one of four
modes (Heat Pump Only, Gas Only, Hybrid or Dual).
In Hybrid mode, the heater automatically switches
between heating the water by means of heat pump or
gas heating in order to maximize efficiency. In Dual mode
the heat pump functionality and gas heater will work in
tandem to heat the pool/spa.
1. Press the MENU SELECT button repeatedly until the
Mode Selection screen displays.
2. Press the UP or DOWN arrows to scroll through the
HEAT PUMP, GAS, HYBRID and DUAL options. The

Remote Mode - Relay
In Relay Remote Mode operation, the heater is started
and stopped by remote relays which are connected to
the remote POOL, COMMON and SPA quick connect
terminals on the back of the control board.
When conductivity is provided between the POOL
and COMMON terminals or the SPA and COMMON
terminals, the heater will start. All other features and
functions (except for the Heater Timer) are still active.
The heater will not heat above 104°F (40°C).
To activate the Relay Remote Mode:
1. Press MENU SELECT repeatedly until the Remote
Mode screen is displayed. Once displayed, press
the UP or DOWN arrows to select RELAY. The last
option shown on the display becomes active.

Heater Timer
This feature is an adjustable timer to allow the heater to
run for a predetermined amount of time (green light ON)
and then turn OFF (green light OFF).
During the selected time frame, the green light is
ON and the heater functions in the normal mode of
operation. When time expires the green light turns OFF
and the heater turns off. Countdown time is in hours
and minutes.
To activate the Heater Timer:
1. Press MENU SELECT repeatedly until the Heater
Timer screen is displayed.
2. Press UP or DOWN arrows to set the amount
of time (range of 10 minutes to 99 hours). Timer
adjusts in increments of 10 minutes.
If the heater is not already on, setting the timer will
activate and start the heater.
3. The user can also change the time while it is active
using the arrow buttons, but only if Remote mode
is OFF. Setting Remote Mode to RELAY or RS-485
disables the Heater Timer at the control panel.
4. Any RS-485 communication received will reset the
timer to zero. The RS-485 overrides the Heater
Timer operation.
5. The timer can be disabled by pressing the DOWN
arrow and MODE buttons at the same time, or by
pressing the ON/OFF button.
