SPA MODE – HEATING
When operating in spa mode display will show SPA – HEAT on the top line and the actual spa water
temperature on the second line.
EXAMPLE:
SPA – 104º
•
To operate in SPA mode user will press the POOL/SPA button (center hand button) once.
After pressing the POOL/Spa button, the display will show “SPA TEMPERATURE” on the
top line and the current temperature set point on the bottom line for 5 seconds. Adjust the set
point by pressing either UP or DOWN until the new set point is reached for spa heating.
•
The display will revert back to “SPA – HEAT” and the current spa temperature after 5
seconds of inactivity and the new set point will be stored.
•
When the spa water temperature falls 1º F below the set point, the control will energize spa
heating mode (compressor) after the time delay has expired.
•
During heating once the water temperature reaches the set point, the compressor turns off.
CHEMICAL USE
Water quality must be checked regularly and maintained within recommended limits at all times.
Failure to maintain the proper water quality will greatly reduce the life of your heater.
•
Never add chemicals directly into skimmer.
•
Automatic chlorinators must be piped downstream from the heater. A check valve must be installed
between the chlorinator and heater to prevent raw chlorine from draining back into the heater. A chemical
trap may be piped at least six (6) inches above the chlorinator. See piping diagram B.
Always maintain the following water quality requirements:
PH LEVEL 7.4 to 7.8
CHLORINE CONCENTRATION 1 to 5 PPM
TOTAL ALKYALINITY 100 to 200 PPM
CALCIUM HARDNESS 100 to 300 PPM
