COOLING MODE
CU type system: P07 = FAN
Control without indoor environment compensation P105 = 0
(control on the water return only).
Water
setpoint = P132: cooling setpoint
Water
setpoint = P133: cooling setpoint
Control with indoor environment compensation (P105 ≠ 0)
(control on the water return depending on the difference between
the ambient temperature and the air setpoint).
Air
setpoint = P130: cool air setpoint
Air
setpoint = P131: cool air setpoint
The air comfort setpoint P130 activates the water control with P132
as the water comfort setpoint.
The air economy setpoint P131 activates the water control with
P133 as the water economy setpoint.
UHCS type installation: P07 = UHCS
The air setpoint activates control. The outdoor temperature does not affect the setpoint value.
The air comfort setpoint P130 activates the water control with P132 as the water comfort setpoint.
The air economy setpoint P131 activates the water control with P133 as the water economy setpoint.
