For SunTouch
®
Control System single body systems (pool
only or spa only), the
HI-TEMP (UP arrow)
button is used
to switch the heater (regardless of the Heat menu setting) and
filter pump on and off. Typically this circuit is used with the
“Manual Heat” feature (see below) for on-demand spa water
heat. The heat temperature settings are displayed on the main
screen. The heater is active when the set temperature is higher
than the water temperature. The heater will switch off when
the water temperature rises above the set temperature. The heat
temperature settings are displayed on the main screen.
The LO-TEMP on and off control is made from the Heat menu
setting. For the SunTouch Control System single body systems (pool only or spa only, see page 35), the
LO-TEMP menu setting is used to switch on and off the heat source and filter pump. A heat selection must be
selected in the Heat menu before the heater is activated. The “Manual Heat” setting does not function with
the LO-TEMP circuit. The heater is active when the set temperature is higher than the water temperature. The
heater will switch off when the water temperature rises above the set temperature.
