Use the solar settings to setup solar or configure solar as a heat pump:
Setting Up Solar Control
: Ensure that the solar temperature sensor is installed.
About Installing Solar Heating:
First, install the solar sensor at the collectors and connect to the
EasyTouch load center. Connect the wires to the SOLAR screw terminals according to the wiring diagram
on page 64. Plug the solar valve actuator cable into three-pin socket marked VLV A on the EasyTouch
motherboard. If a solar booster pump is being installed, connect the pump to a power relay and plug a low
voltage cable from relay into the two-pin socket marked SOLAR on the EasyTouch motherboard.
If HEAT PUMP is selected and is being used in place of a solar heating system, install Solar sensor near the
EasyTouch Load Center.
Note: If Solar is not selected (No), the EasyTouch menu selections display “AUX EXTRA” instead
of “SOLAR.” This allows the solar plug (J17) on the EasyTouch motherboard to be used an
“extra” auxiliary output circuit. The Solar button is used to switch on and off the extra auxiliary
circuit.
To access the Solar menu:
Press the
Up/Down button
to select which solar screen to view. Press the
Right

.
Screen (1/3): ENABLE SOLAR:
Is the pool using solar heat? Select
Yes
or
No
to enable solar heat. To display the solar selection as a heat source in the main
screen, select
Yes
.
HEAT PUMP:
Is a heat pump being used for solar heat? Select
Yes
or
No
to enable
solar as a heat pump.
Heat Pump Control instead of Solar:
Select
YES
if a heat
pump is being used in place of a solar heating system. If Solar is set to heat
pump,
Valve A
is free for other circuits.
Right button:
Select

Screen (2/3): ENABLE FREEZE:
Enable freeze protection when using solar heat.
Select
Yes
or
No
to enable freeze solar protection.
ENABLE NIGHT COOLING:
Select
Yes
or
No
to enable nocturnal cooling. Night
cooling enabled (YES), will circulate water through the system to lower the
temperature during the night hours. Set the temperature in the Heat menu.
Screen (3/3): Solar temperature differential start up and run settings
.
Start:
Set the temperature differential to start heating from 1° to 5°. For example,
if “Start” is set to 5°, this ensures that the solar temperature has to raise by 5°
above the water temperature before it switches on. Once the solar comes on it
will start converging as it is heating. This ensures that it will not continually be
switching on and off.
Run:
Set the temperature differential to stop heating from 2° to 5°. This setting
sets how close to the target set point temperature to switch off solar heat.
