1. During the hot water supply or heating operation without reaching the set temperature the compressor operation frequency stays at a frequency of less than the maximum Hz or lowers down The Stop operation on the remote control will not stop the circulating pump The same for hot water supply heating and cooling on the remote control will not operate the compressor It will not operate even after the reboot delay timer elapsed When the power is turned it starts operation without on operating the remote control The compressor does not operate during the operation of the compressor reboot timer 3 min Even after the power activation the compressor reboot timer continues to be active It may be caused by the high temperature release control release protection control by the temperature of the water heat exchanger or the current release control In order to deal with the temperature increase in the heat exchanger after stopping the operation continues for 1 min after the compressor is stopped When the outdoor temperature TO sensor detection temperature is 20 C or lower the heat pump will not operate in order to protect the compressor and the heater will operate instead The auto restart operation may be working The antifreeze operation may be working If the TWI TWO or THO sensor detects a temperature below 4 C the operation changes from circulating pump gt gt circulating
