4. Usage
14.6) Ambient Temp. to activate first class anti-freezing
14.7) Ambient Temp. to activate second class anti-freezing
14.8) Ambient Temp. to stop second class anti-freezing
14.9) Water Temp. to activate second class anti-freezing
14.10) Water Temp. to stop second class anti-freezing
These parameters are used for setting the anti - freezing protection of the unit in winter time ,
when unit is powered but turned OFF .
When ambient temperature is lower than fist class anti - freezing starting ambient temperature,
unit will circulate the water in the system at interval for anti-freezing.
When ambient temperature drops below second class anti - freezing starting ambient
Temperature,
heat pump unit will start either compressor or backup heating sources to maintain
the water temperature within the range “ Water Temp. to activate second class anti-freezing” and
“ Water Temp. To stop second class anti-freezing ”.
Note: This function is provided to the customer FREE OF CHARGE for helping their house
heating and DHW water system free from freezing up. Customer should always have his own
protection system for preventing the water system from freezing up. We have no responsibility or
obligation if any damage has caused by water freezing.
14.11) Mode Switch during Defrosting
If water temperature is too low , the condenser may have the risk of freezing up and cause
damage the complete refrigerant system . Thus , if water temperature in current working mode
is too low for defrosting , unit will check the water temperature in other circuit. If the water
temperature in other circuit is good enough for defrosting, it will switch the water flow to this circuit
for defrosting operation automatically.
If there is no other circuit , or the water temp in other circuit is also not high enough for
defrosting, unit will stop defrosting and automatically lift up the set water temperature, preparing
for the next defrosting cycle.
If defrosting failed for over three times continuously , unit stops and can only be recovered
by re - powering the machine. Please check the water system at this moment to ensure everything works
properly before re-powering the unit.
Note : This function can only work with outdoor software higher than
, otherwise this function will interrupt the working of the machine during
defrosting all the time.

or AC13I17.WP.V009_T01
14.12) Fan Speed Limit
This function is for reducing the fan speed in order to reduce the noise, however it would reduce the
performance of the heat pump at the same time. The fan speed limitation can be set at down to two
levels 95% and 90%. This function is not recommended unless the noise is strongly
complained by
customer / neighbor .
