Air compressor hot water machine controller plc control unit

Product Detailed Description
The air compressor hot water machine controller is a special controller for air compressor heat pump hot water machines. It has circuit temperature sensors (inlet water temperature, outlet water temperature, water tank temperature, inlet oil temperature, Oil temperature, ambient temperature circuit control output (water pump, circulation pump, oil shut-off valve, water adding valve, heater, frequency converter, cooling fan circuit input protection, such as current interruption protection (for indication Whether the water pipe is short of water), water level protection, fault protection, etc.
The main functions are as follows
,
Temperature display and control
Display the water tank temperature, inlet water temperature, outlet water temperature, according to Set temperature and control the water temperature in the water tank within the set temperature
Display the oil inlet temperature and oil outlet temperature, control the operation of the oil cut-off valve according to the set temperature, and ensure the normal oil temperature of the air compressor
br/> Display the ambient temperature (the working environment controls the cooling fan to dissipate heat according to the set temperature.
, Inverter frequency display and control
It can display the inverter operating frequency, and has control logic optimized for heat pumps. The water tank temperature set according to the oil temperature can effectively control the inverter frequency to ensure a constant water tank temperature.
,
Oil temperature protection
When the air compressor oil temperature is too low, the heat exchange operation will be stopped. And can control the auxiliary heater heating according to the set water tank temperature.
, Water level display and control
Can display the water level, and control the water adding valve according to the water level.
, Fault number alarm
Low water level alarm, high water level alarm, flow interruption alarm and fault alarm.
,
Period operation
Moisture adding period, circulating pump period and heater heater period can be set There are two operating periods, which only operate during these periods and do not operate at other times.
,
The controller has two operating modes to choose from, manual mode and automatic mode.
, Controller clock correction function .
. The installment payment function can set the installment payment time and installment payment password at the factory.
. Manual control of water addition, heating,
circulation pump, can be forced to work manually.
