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,
