Control details
When using a Ø19.1 pipe for the existing piping, set the switch to ON.
This case may decrease heating capacity depending on the outside air
temperature when heating or on a room temperature.
When using the power save function, set the switch to ON. This setting
controls the compressor frequency lowering (about 10%) according to the
heat exchange temperature of the hydro unit during a heating or hot water
supply operation.
This control enables the function that prevents snow from entering the draft
air duct through the fan guard or a heat exchanger gap and causing motor
lock. If the outside air temperature is 0 °C below, this control operates the
outdoor fan in W5 even if the compressor is not in operation.
If the defrosting interval is shorter than the standard, the jumper wire is cut.
For the control details or how to cut the jumper wire, see defrosting control.
If the maximum value of compressor frequency need to be lowered, cut the
jumper wire shown on the left.
This control lowers the maximum frequency when hot water supply, heating,
or cooling is in operation.
In this case, the maximum capacity decreases.
