START UP & SETTING OPERATING CONTROLS
1. Applying Power to The Controller:
A. When power is first applied, the control performs a lamp test and the display will read
[888]. Additionally, all status LED’s lights will illuminate for 4 seconds and then go off
for 1 second.
B. The control will then display the actual temperature as long as the pool-circulating pump
is on.
C. If the pool-circulating pump is off, the control will display the [FLO] (No Water Flow)
code message indicating water is not being circulated though the heat pump.
2. Turning The Heat Pump ON:
A. Once electrical power is supplied to the heat pump, the pool-circulating pump is
activated, and the control has successfully completed the self-test, the unit is ready to
operate.
B. The control is shipped with the SPA set point in the [OFF] mode and with the POOL set
point selected. The heat pump is automatically switched off if a set point below 60 °F
has been selected. In the [OFF] mode, the control will display the water temperature as
long as the pool water-circulating pump is operational. In the event water is not
circulating through the heat pump, the control will display the [FLO] (No Water Flow)
code message.
C. Using the Up
arrow key, increase the desired temperature until it exceeds the value of
the actual temperature displayed. (Note: See #8, below, if “000” is displayed upon
pressing up or down arrows.) Once the desired temperature has been entered, the display
will read the actual temperature and the heat pump will start to operate. Both the
compressor and fan must be operating before the “Heat” LED will illuminate.
3. Turning The Heat Pump OFF:
A. Using the Down
arrow key, decrease the desired temperature until the display reads
[OFF]. The heater will shut off, and will remain off until the temperature set point is
raised above 60° F.
B. NOTE: Each time the heater is turned off, either manually, or by the thermostat
becoming satisfied, there will be a 4-minute delay prior to restarting.
4. Selecting Pool / Spa Thermostat Settings:
A. Depress the Pool / Spa key to toggle between the pool and spa temperature set points.
B. The pool / spa led indicator lights located to the left of the temperature display will
confirm the selected temperature set point.
