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. If “HEAT PUMP” is selected and is being used in place of a solar heating system, install Solar sensor near the EasyTouch Load Center. Connect the wires to the SOLAR screw terminals according to the wiring diagram on page 60. 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.
