3c: Digital Controller
3c.1: Description
The sophisticated Digital Controller (thermostat) provides temperature readout and set point
temperature adjustment. It also monitors compressor operation, controls the de-icing system
and indicates the operational status of the heater.
3c.2: Temperature Display
The temperature display indicates water temperature in the inlet of the heater (for pool heating)
or the outlet (for water heating). Therefore the water circulation pump must be operating for an
accurate water temperature to be displayed. If all safety devices are closed except for the water
flow pressure switch, the temperature display will operate. Once water flow commences the
system will be able to detect the circulating water temperature.
During operation, the display will indicate the actual water temperature. To show the desired
water temperature press the “SET” button 3 times, the display is now showing the temperature
set point. To then go back to the actual water temperature display, press the “SET” button again.
To change the desired water temperature, press the “SET” button 3 times, then, using the arrow
up or arrow down buttons, program the desired water temperature. Finally press the “SET”
button again to lock in the new setting and display the actual water temperature once more.
