NOTE
If the volume of balance tank (9) larger than 30L, the buffer tank(8) is unnecessary, otherwise the buffer tank(8) should be installed and the
total volume of buffer tank and balance tank should larger than 30L.The drain valve (6) should be installed at the lowest position of the
system.
An independent backup heater can be selected and installed in the door, which can provide additional heating source and ensure better
performance of the system when the ambient temperature is low.
Mixing station
As the unit is mainly to provide middle-temperature and high-temperature water, when connecting floor heating, the need to increase the
mixing station (13) before the floor heating.
Pump operation and space heating and cooling
According to the season, the unit (1) will switch to either heating or cooling mode according to the temperature detected by the standard
controller (or optional wired controller (4)). When space heating/cooling is requested standard controller (or optional wired controller (4)), the
pump will start operating and the unit (1) will switch to heating mode/cooling mode. The unit (1) will operating to achieve the target cold/hot
water leaving temperature.
In the cooling mode. the motorized 2-way valve (14) will be set to closed to prevent cold water running through the floor heating loops (FHL).
CAUTION
When circulation in each fan coil units (FCU 1...3) is controlled by remotely controlled valves (M1...3), it is important to provide a
by-pass valve (15) to avoid the flow switch safety device from being activated. The pass-by valve should be selected as such that
at all time the minimum water flow. It is recommended to select a pressure difference controlled by-pass valve.
