SET-POINT COMPENSATION 

The operation SET-POINT can be fixed or determined by a compensation slope according to the 
value given by the compensation sensor. 
Both A1 and D1 temperature loops can be temperature 
compensated (the SC sensor is necessary) or humidity 
compensated (SH sensor). It is necessary to set the 

Cth

 

parameter to state the temperature and humidity 
compensation.

 

Both A2 and D2 humidity loops can be 

temperature compensated only (the SC sensor is 
necessary). 
The compensation slope is a broken line touching two 
points and given by four values. 
Depending on the value given by the sensor, a set-point value shall be defined in a range between 
a minimum and a maximum. 
“Negative Compensation” means when the operating set-point increases while the compensation 
sensor value decreases. 
“Positive Compensation” means when operating set-point 
increases by the increasing of compensation sensor 
value. 
It is possible to set Negative and Positive Compensations 
both for temperature and humidity control loops. 
Each operation set-point value, both by temperature 
(heating and/or cooling) and by humidity 
(humidification/dehumidification) control loop can be 
associated to a relevant slope resulting by two values: 

 

- SET-POINT 1 corresponding to TEMPERATURE 1 
- SET-POINT 2 corresponding to TEMPERATURE 2 

 

If the Compensation Sensor is present and the Compensation of an Operating Mode is enabled, it 
is necessary to determine the four values of the curve. Such values become eight in case of 
Operating Mode A3, A4 and D3 because it is necessary to set compensation both for the heating 
and for the cooling loops. In the latter case, if compensation should be disabled for one of the two 
Loops only, it is necessary to set the minimum Set-point equal to the maximum value achieving a 
fixed operation Set-point. It is not possible to enable compensation in Operating Mode D4. 
 
While the A2 and D2 loops can be compensated through the SC temperature sensor, loops A1 and 
D1 may be temperature or humidity compensated. The selection is made under the Level II menu 
(label Cth).

 

For the temperature compensation the Compensation Sensor used is the one connected to 

SC 

input, if not differently specified (“SC sharing” see paragraph related to LinkBus). To enable 
Compensation first connect or share the Compensation Sensor. If compensation is enabled on any 
Operating Mode and the Compensation Sensor is not connected correctly to 

SC 

terminal or is not 

shared correctly with other devices, the Anomaly led 

@

 

lights up and the control Set-point 

becomes the value set for fixed point, i.e. without Compensation. 
For humidity compensation the possible absence of SH sensor does not generate any fault since 
its value can be 0. 
By humidity control loops, the possibility to compensate the set point depending on 

SC

 signal is 

used either to perform the remote setting of humidity set point through a potentiometer (see remote 
set page 14) or e.g. to compensate linearly minus the room humidity set according to the inner 
temperature of glass surface (anti-frost function in swimming pools or wet environments). 
In this case, the temperature sensor connected to 

SC

 must be located in the indoor part of the 

glass wall. 
For all compensation parameters settings see page 18
