Product Description
function description
1.1 hydronic heating 
1.1.1 flowsheet of hydronic heating
power on→water level switch test→ water pressure switch test→cycle water pump work(16s)→     water flow switch test→fan work(6s)→compressor work(when low water level disconnect,cool water supply switch on, compressor,fan,cycle water pump work.
1.1.2,Cool water supply controlling
(1)when low water level switch disconnected, cool water supply switch on and begin supply water, cycle water pump startup, fan off, compressor off.
(2)when low water level switch on, cycle water pump on, fan on,compressor on, hydronic heating begin. meanwhile water supply valve begin to supply water according to the preset water supply temp L7.:if water tank temperature≥L7,water supply valve open,supply water;if water tank temperature≤L7-5degree,water supply valve close,stop supplying water.
(3)after high water level close up, stop supplying water. If high water level has closed up before, when it disconnect again, not supply water at once, it will supply water until middle water level disconnect.
Notice::if L7=20ºC,water supply is not controled by water temperature.
1.1.3,water temperature controlling
Range of water temperature controlling:35-60ºC,
1.1.4 Running controlling
1.2 Instantly heating
1.2.1 Power on→water pressure switch test→open water supply valve to supply water→fan on→compressor on, after high water level connected, water supply valve close, if water tank temperature doesn't reach preset temperature, cycle water pump on, water was heating to preset temperature circularly, then power off.
1.3 Supply water controlling
(1)when high ,middle,low water level switches all disconnect, water supply valve supply water, then check water pressure switch, if water pressure switch is closed up, then fan on, compressor on,  thermostat on, begin to supply water untill high water level switch closed up, thermostat and water supply valve close ,stop supplying water.
(2)if high water level switch have been closed up, when the high water level switch disconnect, it will not supply water at once, it must untill middle water level disconnect. Then water supply valve on, fan on, compressor on, thermostat on.
1.4 Water temperature controlling
Range of water temperature controlling: 35-65ºC, when preset temperature reach 60ºC, if want to set the water temperature >60ºC, press key over 6s , when hearing a "toot" voice , move away finger , press key again, now the max water temperature can be set at 65ºC.
