9.6.2.3 With CN02 delay, close outdoor side water pump;
9.6.2.4 With EV03 delay, close indoor side water pump, 4 way valve.
9.6.3 TURN ON process at HOT WATER
When operate TURN ON at hot water mode, the controller will work as the following
process:
9.6.3.1 Start daily hot water pump, indoor side water pump (SF10=0), 4 way valve;
9.6.3.2 With CN01 delay, start outdoor side water pump;
9.6.3.3 With CM05 delay, and the water flow switch turned on, time data CM02 meeted,
start one compressor.
9.6.3.4 With CM03 delay, time data CM02 meeted, start the other compressor if has.
9.6.4 TURN OFF process at HOT WATER
When operate TURN OFF at hotwater mode, the controller will work as the following
process:
9.6.4.1 CM01 meeted, close one compressor;
9.6.4.2 With CM04 delay, CM01 meeted, close the other compressor if has;
9.6.4.3 With CN02 delay, close outdoor side water pump;
9.6.4.4 With EV03 delay, close daily hot water pump, indoor side water pump, 4 way
valve.
9.6.5 HOT WATER mode priority
9.6.5.1 When the unit is working at heat mode, the controller get signal to produce daily
hot water, the daily hot water pump will start at once, the indoor side water pump will be
controlled by SF10. At that time, the unit will transfer to HOT WATER mode directly
untill reach the daily hot water temperature, then turn back to HEAT mode directly.
9.6.5.2 When the unit is working at cool mode, if the controller get signal to produce
daily hot water, the unit will stop first, then start the HOT WATER mode untill reach the
daily hot water temperature, then stop again to start the COOL mode.
Protection function
9.7.1 Anti-freeze protection at stop situation
The anti-freeze function will be valid only at the following conditions:
 The controller keeps at stop mode, but the unit is still connected with power
supply.
 OT≤SF06 (During anti-freeze working, when OT≥SF06+SF07, it will quite from the
anti-freeze running.)
 At the above conditions, and SF02=1, when ST≤SF08, the indoor side water pump
is turned ON, a continuous blink warning code WN01 will appear on the LCD, until
ST≥SF08+SF09, it will quite from the anti-freeze work.
 At the above conditions, and SF03=1. when STO≤SF08, the outdoor side water
pump is turned ON, a continuous blink warning code WN02 will appear on the
LCD, until ST≥SF08+SF09, it will quite from the anti-freeze work.
9.7.2 Low pressure protection (Code: AL01)
After starting the compressor, it will check the low pressure at AL09 delay. If DI2=OFF,
all the compressors will be stopped, other parts will keep its original state. A continuous
blink code AL01 will appear on the LCD, until DI2=ON, the unit will turn to its normal
work.
