G1 Valve
DHW and AC / Heating
G1: DHW/AC / Heating Valve
In DHW mode, the G1 valve is powered off. In AC mode, G1 is powered on.
Function Selection Switch: SW1 must be set for SW1-5 OFF to activate G1, SW1-5 ON to deactivate. SW1-6
“OFF”, DHW is activated, SW1-6 ON DHW is deactivated. The main power must be cycled off then on for
switch settings to take effect. Parameter 09 will show the switch status.
DHW target setting temperature is the tank water temperature measured with the DHW sensor, not the
inlet water temperature. If the target temperature is 122°F, refer to page 37 to set the DHW temp, and the
differential is 2°c, it means, when the DHW tank reaches 122°F, the compressor will stop. When the DHW
tank temperature is lower than 119°F, the compressor will start.
Parameter 11 is to avoid high pressure protection, P1 errors, during DHW heating. Some older tanks use a
short coil inside the tank, if the heat pump is connected to the short coil, the heat pump capacity may be
too high creating too much heat and triggering the high pressure protection switch. If this happens,
parameter 11 may be changed to adjust the compressor frequency lower. The adjusted number is decided
by the installer when testing the DHW function. If you don't use DHW, no changes to parameter 11 are
necessary.
