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)
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!

It can be set to ON or OFF, factory setting is ON; this setting will be effective for ROOMHEAT 1 and ROOM
HEAT 2 modes.
To set ON: the water pump will keep running even if feed water temperature reaches setting temperature in
ROOMHEAT 1 mode; the water pump will keep running even if room air temperature reaches setting
temperature in ROOMHEAT 2 .
To set OFF: the water pump will stop running as soon as feed water temperature reaches setting
temperature in ROOMHEAT 1; 20 minutes later water pump will restart and running 3 minutes for detecting
water temperature to see if necessary to restart heat pump;
The water pump will stop running as soon as room air temperature reaches setting temperature in
ROOMHEAT 2; the water pump will restart as soon as room air temperature decreased.

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.
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).
