ANTI-CONDENSATION FUNCTION
The management of this function requires the zone N-THC thermostat.
When the system is set to cooling, excessive ambient humidity may cause the formation of condensation.
This can be counteracted by increasing the delivery water temperature proportionally with the humidity increase detected in the environment (see the
following chart).
The function is enabled using the parameter (
0156
for the system,
0171
for the mixed zone), if the system cooling climate curve (
0154
) is enabled.
If the relative humidity, measured by the ambient thermostat, exceeds the value set at parameter
0157
(for the low zone:
0172
) the water setpoint
increases until it reaches the maximum temperature. The maximum water temperature is the result of the sum of the setpoint calculated according
the cooling climate curve and the value set in parameter
0158
(for the low zone:
0173
).

Using the parameter it is po
ssible to configure a digital output as dehumidifier control. The “external” dehumidifier is activated if the humidity detect

by the zone thermostat probe exceeds the value set in parameter
0172
.
