Pool and Spa Heater Installation and User’s Guide
P/N S794 Rev. H 8-11-14
TEMPERATURE SETTING
The heater comes factory set at 78° F for the pool mode and 100° F for the spa mode. Using the up and down arrows, you
can set the thermostats to a minimum temperature of 65° F, or a maximum of 104° F. If you desire to heat only one body
of water, the thermostat is capable of an off mode. As an example, if you only wish to heat the spa and not the pool, simply
depress and hold the pool down arrow, and the thermostat will lower its setting to 65° F then go to an off mode.
