Control Specification
SiUS04-924
Function and Control 31
3.3.2 Four-Way Valve Switching
Outline
During the heating operation, current must be conducted and during cooling and defrosting, current
must not be conducted. In order to eliminate the switching sound (as the four-way valve coil
switches from ON to OFF) when the heating is stopped, the delay switch of the four-way valve must
be carried out after the operation stopped.
Detail
The OFF delay of four-way valve
Energize the coil for 150 seconds after unit operation is stopped.
3.3.3 Four-Way Valve Operation Compensation
Outline
At the beginning of the operation as the four-way valve is switched, acquire the differential pressure
required for activating the four-way valve by the operating frequency output, which is more than a
certain fixed frequency, for a certain fixed time.
Detail
Starting Conditions
1. The MRC/W turns ON when the compressor starts for heating after the MRC/W has been OFF
with compressor halted.
2. The MRC/W turns OFF when the compressor starts for cooling after the MRC/W has been ON
with compressor running.
3. The compressor starts for the first time after reset.
4. The compressor starts after suspension caused by the trouble of cooling/heating changeover.
Set the lower limit frequency (cooling :
Hz, heating :
Hz) for
seconds with any
conditions 1 through 4 above.
3.3.4 3-Minute Standby
Prohibits turning ON the compressor for 3 minutes after turning it off.
(Except when defrosting.)
