•Adjusting the pool water temperature: To display the pool water temperature settings, first activate
the “Pool” circuit. To activate the circuit, press the MENU button, then press the RIGHT arrow
button, then press the Up or Down arrow button. The pool water temperature settings are displayed.
•Press the Left or Right button to adjust the pool water set temperature. The currently selected heat
source is displayed on the lower display line. The spa water temperature can be adjusted from 40° F
to 104° F (4° C to 40° C). Degree units are displayed in either Fahrenheit or Celsius (see page 22).
Note: To display the air temperature setting on the main screen, the air sensor must be enabled.
For more information see “Advanced Menu,” on page 24.

Selecting the heat source

From the Heat menu you can set the spa and pool water temperature and select the heat source. The spa or pool
water will heat to the settings specified. The SunTouch system is compatible with solar and conventional heaters.
The SunTouch will use the heating source that is selected.

To select the heat source:

The heat source selections are:
•OFF - No heating, even though the filter pump and other circuits may be operating.
•HEATER - Use gas heater only. Use the UP arrow button to switch the filter pump then the heater
on. Once the heater is switched on it will continue heating the water until the heater’s current highest
set point temperature triggers the heater sensor (approximately 104° F or 40° C). Note that setting
the “Heat Source” to “Heater” does not activate the filter pump. The filter pump must first be
switched on before the heater switches on. The heater will not run if water flow is not detected. Do
not activate the heater without running the pump.
•SOLAR - Solar heating system selected as the only heat source. Solar heat can be switched on and
off in the “Solar” menu (see page 20). When solar energy is active the solar relay is switched on to
activate the booster pump (if installed) and rotate the valves to divert water through the solar
collector panels.
•SOLAR PREF. - (Solar Preferred) - Used when solar and gas heating are combined. This feature
uses solar heating energy when it is most effective, then switch to gas heating when solar heating is
not available. In order to display “Solar Pref.” on the main screen, enable “Solar” in the Solar menu
(see page 20).
Note: Solar Only mode - If a solar heating system is the only heat source, enable solar in the “Solar”
menu (see page 20).
Press either Up or Down
button select the heat
source. Press the Right
button to save and exit.
