HI-TEMP (Up Arrow button)

For SunTouch single body systems (pool only or spa only, see page 36), 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.

LO-TEMP (Spa) Menu Operation

The LO-TEMP on and off control is made from the Heat menu setting. For SunTouch single body systems

(pool only or spa only, see page 36), 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.

MANUAL HEAT (Off/On)

By default, the spa Manual Heat feature is always set to “ON.” This allows the spa to begin to heat whenever the SPA, Up arrow button is pressed, regardless of the heat source setting in the Heat menu (see page 4).

This feature allows the spa to be filtered daily with the heater switched off. The optional QuickTouch QT4 wireless remote can also be used to switch the spa heater on. This feature will not work for solar systems, only gas and electric heaters.

MANUAL HEAT

To enable or disable spa heat when switched on manually:
