10.2.3.1 Set target outlet water temperature

Each of the 2 Water Cycles will have an independent target outlet water temperature. And Target outlet water temperature
is combination of Water Cycle set-point and compensation of Water ECO offset / Room thermostat.
(1) Cooling Water Cycle set-point can be define as follows:
Ttwo_c1 _water_c_p as Water Cycle 1.
Ttwo_c2 _water_c_p as Water Cycle 2.
There are 2 ways to set Water Cycle set-point as follows:
● Fixed, refer to 1.2.3.1.1 (1)
● OTC point, refer to 1.2.3.1.1 (2)
(2) Cooling Compensation of Water ECO offset defined as following, refer to 1.2.3.1.2
c1_wate_c_Ecoofs as Water Cycle 1.
c2_wate_c_Ecoofs as Water Cycle 2.
NOTE: Compensation of Water ECO offset is valid when the function is active.
(3) Cooling Compensation of Room thermostat defined as following, refer to 1.2.3.1.3
Compenc_c1 as Water Cycle 1.
Compenc_c2 as Water Cycle 2.
NOTE: Compensation of Room thermostat is valid when the function is active.
(4) Cooling Target outlet water temperature defined as
Ttwo_Cycle 1_c as Water Cycle 1.
Ttwo_Cycle 2_c as Water Cycle 2.
Cooling Target outlet water temperature is combination of Water Cycle set-point and compensation of Water ECO offset
and Room thermostat.
Ttwo_Cycle 1_c= Ttwo_c1 _water_c_p - Compenc_c1 + c1_wate_c_Ecoofs
Ttwo_Cycle 2_c= Ttwo_c2 _water_c_p - Compenc_c2 + c2_wate_c_Ecoofs
NOTE: Compenh_c1 and Compenh_c2 is forced as 0 when water Calculation Regulation Mode set as [ Fix ].
(5) Cooling Target outlet water temperature is regulated as following scope
c1_wate_c_min ≤ Ttwo_Cycle 1_c ≤ c1_wate_c_max
c2_wate_c_min ≤ Ttwo_Cycle 1_c ≤ c2_wate_c_max
The configuration of this option should be done through the master controller
Configuration → Space cooling→Cycle 1→ Working range
Mark
c1_wate_c_max Max. Water Supply Temp
c1_wate_c_min Min. water Supply Temp
Configuration → Space cooling→Cycle 2→ Working range
Mark
c2_wate_c_max Max. Water Supply Temp
c2_wate_c_min Min. water Supply Temp
NOTE：
1. It is the installer's responsibility to make sure no unwanted situation occurs (for example: water temperature setting too
low into Refreshing floor installation).
2. In case of Radiator and Refreshing floor installation, Radiators valve should be closed and disabled by user and the
system only works for refreshing floor.
