Control process
Turn on process at heating mode
1.)
Start water pump , check water flow switch
2.)
5 seconds after water flow switch closes, if there is heating demand, start fan and compressor
Turn off process at heating mode
1.)
Switch off compressor
2.)
After 5 second’s delay, switch off fan motor
3.)
After 30 seconds’ delay, switch off water pump .
Turn on process at cooling mode
1.)
Start water pump and 4 way valve, check water flow switch
2.)
5 seconds after water flow switch closes, if there is cooling demand, start fan and compressor
Turn off process at cooling mode
1.)
Switch off compressor
2.)
After 5 second’s delay, switch off fan motor
3.)
After 30 seconds’ delay, switch off water pump .
4.)
After 60 seconds’ delay, switch off 4 way valve.
Turn on process at hot water mode
1.) start 3 way valve and water pump, check water flow switch.
2.) 5 seconds after water flow switch closes, start fan and compressor
Turn off process at hot water mode
4.)
Switch off compressor
5.)
After 5 second’s delay, switch off fan motor
6.)
After 30 seconds’ delay, switch off water pump and 3 way valve.
Hot water priority:
When unit is heating, if there is a call for hot water , it start 3 way valve at once and turn to
hot water mode directly. It will revert back to heating mode after hot water reach set
temperature.
When unit is cooling, if there is a call for hot water , it stops compressor first and then start at
hot water mode , it stops compressor again when hot water reach set temperature before it
revert back to cooling mode.
Water pump control (NO2)
water pump runs as below from stop to running mode:
EV01=Continuous work, water pump will continue to run until unit stops.
EV01=work by regulation, water pump will be ON when compressor is ON, will be OFF when
compressor is OFF.
4 way valve control (NO3)
4 way valve is OFF on below conditions. It is ON at other conditions.
1.)
Heating mode, hot water mode, or h hot water mode
2.)
Producing hot water on c hot water mode.
