The HEAT MODE RUNNING operation is used to
check the operation of the system in space
heating mode
During the HEAT MODE RUNNING operation the
unit leaving water set temperature is 35°C. The
current actual leaving water temperature is
displayed on the user interface. When the HEAT
MODE RUNNING operation starts, the heat pump
first runs for 10 mins.
After 10 mins:
•
On systems where an auxiliary heat source
(AHS) is installed, the AHS starts and runs for
10 mins (whilst the heat pump continues
running), after which the AHS stops and the
heat pump continues to operate until the
water temperature rises to the set
temperature or the heat mode running
operation is exited by pressing OK.
•
On systems where a backup electric heater is
being used, the backup heater turn on (on
models where the backup heater has a simple
on/off control function). 3 mins later the
backup electric heater will turn off. The heat
pump will then operate until the water
temperature rises to the set temperature or
the next command is received.
•
On systems with no auxiliary heat source
(AHS), the heat pump will then operate until
the water temperature rises to the set
temperature or the next command is received.
•
If any error code is displayed during the cool
mode running operation, the cause should be
investigated

The DHW MODE RUNNING operation is used to
check the operation of the system in DHW mode
During the DHW MODE RUNNING operation, the
DHW set temperature is 55°C.
The tank boost heater will turn on once the heat
pump has run for 10 mins.
The tank boost heater will turn off 3 mins later
and the heat pump will operate until the water
temperature rises to the set temperature or the
next command is received.

Before floor heating, if a large amount of water
remains on the floor, the floor may be warped or
even rupture during floor heating operation, in
order to protect the floor, floor drying is
necessary, during which the temperature of the
floor should be increased gradually.
During first operation of the unit, air may remain
in the water system which can cause
malfunctions during operation. It is necessary to
run the air purge function to release the air
(make sure the air purge valve is open).
TT11SS is the target outlet water temperature in
preheating for floor mode.
tt__ffrriissttFFHH is the time last for preheating floor.
The operation of the unit during preheating for
floor described in the picture below:

start delay in space heating mode.
Whilst the preheating for floor operation is
running, the number of minutes that it has been
running for and the heat pump
’
s leaving water
temperature are displayed on the user interface.
During the preheating for floor operation all
buttons except OK are inactivated.
To exit the preheating for floor operation, press
OK and then select YES when prompted.
