Space heang
Cooling or heang mode is set via the room thermostat, water temperature is set on the user interface. 1) When any “CL”
of all the thermostats close, system will be set at cooling mode. 2) When any “HL” of all the thermostats close and all “CL”
open, system will be set at heang mode.
The circulaon pumps operaon
1) When the system is in cooling mode, which means any “CL” of all the thermostats closes, SV2(7) keeps OFF, P_o(6) starts
running;
2) When
the system is in heang mode, which means one or more
“HL” close and all “CL” open, SV2(7) keeps ON, P_o(6)
starts running.

Zone1 can operate in cooling mode or heang mode, while zone2 can only operate in heang mode; While installaon, for
all thermostats in zone1, only “H、L” terminals need to be connected. For all thermostats in zone2, only “C、L” terminals
need to be connected.
1) The ON/OFF of zone1 is controlled by the room thermostats in zone1. When any “HL” of all thermostats in zone1 closes,
zone1 turns ON. When all “HL” turn OFF, zone1 turns OFF; Target temperatu
re a
nd operaon mode are set on the user
interface;
2)
I
n heang mode, the ON/OFF of zone2 is controlled by the room thermostats in zone2. When any ”CL” of all thermostats
in zone2 closes, zone2 turns ON. When all “CL” open, zone2 turns OFF. Target
temperature is set on the user interface; Zone 2 can only operate in heang mode. When cooling mode is set on the user
interface, zone2 keeps in OFF status.
The circulaon pump operaon
When zone 1 is ON, P_o(6) starts running; When zone 1 is OFF, P_o(6) stops running;
When zone 2 is ON, SV3(8.1) is ON, P_c(8.2) starts running; When zone 2 is OFF, SV3(8.1) is OFF, P_c(8.2) stops running .
The floor heang loops require a lower water temperature in heang mode compared to radiators. To achieve these two
set points, a mixing staon is used to adapt the water temperature according to requirements of the floor heang loops.
The radiators are directly connected to the unit wat
er c
ircuit and the floor heang loops are aer the mixing staon. The
mixing staon is controlled by the unit.
