4-way Valve Control in Heating
Unitary: 50s later after compressor start up, the 4-way valve start to operate. When compressor stops or unit is not
in heating mode, the 4-way valve is closed after compressor stop for 2 minutes and 55s.

Electric Heater Control
If compressor has not run for a long time, the refrigerant will deposit on the bottom of compressor and mix with the
refrigeranr oil. When re-startup, because low pressure reduces, refrigerant will be segregated from the refrigerant
oil and cause soam in the oil, which will make compressor exhaust a lot of oil. Therefore please stop heating the
compressor bottom to ensure the low pressure in startup period should not go down greatly.
• Ambient temp. TA≤32degree, when compressor stops, the electric heater will be electried.
• When TA≥32degree, or compressor running, the electric heater will be off.

Multi: Protection when 4-way valve can not reverse in heating: 15 minutes later after compressor startup, if
indoor coil average temp. is below 5degree and keeps for 1 minute, the unit will stop and occur the 4-way valve
protection.
