state parameter setting state), click the heating allow button,
the button indicator lights up, and the controller allows
heating output. Click the "heating allow" again, indicator
light goes out, control device prohibits heating output.
5. Cooling control
In the non-set state (invalid in the state of temperature
setting and internal parameter setting), click the cooling
allow button, the "cooling allow" button indicator light is on,
the cooling 1 compressor has a cooling output; when the first
set temperature reaches the setting value, the cooling 2
compressor has a cooling output. Then, click the cooling allow
button, the "cooling allow" indicator goes out. The cooling
controller prohibits the cooling output. The cooling 1
compressor and the cooling 2 compressor have no cooling output.
When PV2 ≥ SP2 + od2 (the second temperature measurement
value ≥ the second temperature set value + the second
compressor opening deviation), the cooling 2 compressor has a
cooling output, the "cooling 2" indicator lights up; when PV2
≤ SP2 - cd2 (the second temperature measurement value ≤ the
second set temperature setting value - the second compressor
closing deviation), the cooling 2 compressor has no cooling
output, and the "cooling 2" indicator light goes out.
