ADDDIF TEMP
Additional electrical heater restart determined by water temperature degeneration: it is adjustable from 1 to
10 degree (factory setting is 4 degree); the electrical heater will stop when the water get to setting
temperature, then restarts as soon as the water temperature decrease 4 degree (factory setting)
OUTADD.HEAT ON (OFF)
To control outdoor unit electrical heater (bottom electrical heater, evaporator heater), factory setting is ON,
the heater will start when ambient temperature is less than 0 ˚
ɋ
, and stop when ambient temperature is
more than 2˚
ɋ
When the outdoor electrical heater is select OFF, the outdoor heater can not start automatically.
Display : OUT ADD . HEAT OFF
HDO ON ( )
Choose "
" to activate the function 'External signal controls heat pump to start or stop'; there are two
signal connections (NC), when external signal switch on them, the compressor, electrical hearer and motor
will stop running (The water pump will keep running if the operation mode is 'Room heating'); After switch
off them, the compressor, electrical heater, motor will restart and work as previous setting.
This function is for the countries which electricity has two different prices in high peak and low peak that
peak electricity;
they can use signal to stop heat pump when in high peak electricity and start the heat pump when in low
Notice: never input electricity directly to HDO terminals!
ADD DELAY : ( 3 to 10 Min adj ustable , factory setting is 10 M )
Time delay of electrical heater starting: from 3 to 30 minutes adjustable, factory setting is 10 minutes. For
example, since compressor has been running 15 minutes, when 10 minutes
（
factory setting
）
later the
return water temperature remain or decrease, the electrical heater will start automatically.
WATER PUMP
ADD ENFORCE
This function is only available for WARMWATER( water tank heating);when you select"ON",the ADD
(additional electrical heater) will start enforcedly as soon as compressor start, then stop as soon as water
reach setting temperature; when you select "OFF",the ADD only start after fulfill two other conditions
( ADD START and ADD DELAY).
ADD START : ( 10 to 65 degree adjustable , factory setting is 40 degree )
Electrical heater start water temperature, it is adjustable from 10 - 65°C, factory setting is 40°C, this
means when compressor heat the water temperature over 40°C, then allow the electrical heater to start,
this setting is for energy-saving and water tank heating (WARMWATER) only.
Press button RIGHT once will change from 0/0 to 3/10, press the button again will change to 3/10, press again
will change to 3/15, press again will change to 3/20, press again will return to 0/0
0/0 means water pump (for heating) will keep running when house or water tank reach setting temperature in
ROOMHEAT 1 and ROOMHEAT2.
3/10 means that under ROOMHEAT 1 and ROOM HEAT 2; if the setting temperature reach and the
compressor stop, the water pumps (for heating) will runs 3 minutes to detect the water temperature, if no need
to keep running the water pump will stop 10 minutes, then runs 3 minutes again to see if need to restart
compressor and keep water pump running.
3/15 means that under ROOMHEAT 1 and ROOM HEAT 2; if the setting temperature reach and the
compressor stop, the water pumps (for heating) will runs 3 minutes to detect the water temperature, if no need
to keep running the water pump will stop 15 minutes, then runs 3 minutes again to see if need to restart
compressor and keep water pump running.
3/20 means that under ROOMHEAT 1 and ROOM HEAT 2; if the setting temperature reach and the
compressor stop, the water pumps (for heating) will runs 3 minutes to detect the water temperature, if no need
to keep running the water pump will stop 20 minutes, then runs 3 minutes again to see if need to restart
compressor and keep water pump running.
