6. Room Thermostat Control (Optional)

It is possible to set the room temperature by using the Remote controller sensor or the Remote sensor.
The thermostat is turned ON or OFF according to the following ΔTr, ΔTw.
ΔTr (Cool) = Room temperature – Setting room temperature
ΔTr (Heat) = Setting room temperature – Room temperature
ΔTw (Cool) = Water outlet temperature – Setting water temperature
ΔTw (Heat) = Setting water temperature – Water outlet temperature
Difference of air conditioning = 1˚C
* Setting water temperature in Cooling mode = Setting room temperature - 5˚C
Setting water temperature in Heating mode = Setting room temperature + 5˚C
Heating mode
Thermo ON conditions = a and b
a. Δ Tr (heat) > Difference of air conditioning
b. Δ Tw (heat) ≥ Thermo ON margin
Thermo OFF conditions = (a or b) and c
a. Δ Tr (heat) < -1 × Difference of air conditioning
b. Δ Tw (heat) ≤ Thermo OFF margin
c. Not in Force Thermo ON
Cooling mode
Thermo ON conditions = a and b and (e or c and d)
a. Δ Tr (cool) > Difference of air conditioning
b. Δ Tw (cool) ≥ Thermo ON margin
c. Outdoor temperature < 10˚C
d. Inlet water temperature ≥ 7 × (Outdoor temperature -10) / (-17) + 10
e. Outdoor temperature ≥ 10˚C
Thermo OFF conditions = (a or b) and c
a. Δ Tr (cool) < -1 × Difference of air conditioning
b. Δ Tw (cool) ≤ Thermo OFF margin
c. Not in Force Thermo ON
