Space heating
About space operation modes
This unit is a heating only model. The system can heat up a space,
but NOT cool down a space.
Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating is prohibited.

Description
[4.3.1]
[4-02]
Space heating off temperature: When the
averaged outdoor temperature rises
above this value, space heating is turned
off.
▪ 14°C~35°C
Number of zones
The system can supply leaving water to up to 2 water temperature
zones. During configuration, the number of water zones must be set.
