7.5.6 Dual set point control
Applies only to installations with different heat emitters which require different set points (e.g. fan coil and floor
heating).
Dual set point control makes it possible to generate two different set points. The selection between the two set
points is available by the remote contact.
If the Dual set point control contact is CLOSE, the second set point is activated.
The first set point (Zone1) Heating/Cooling is the set point selected on the Remote controller.
In Heating mode the first set point (Zone1) can be a Fixed value or by Climatic curve.
In Cooling mode the first set point (Zone1) can be a Fixed value or by Climatic curve.

Set point for Zone2 is
Contact OPEN = Set point 1
Contact CLOSE = Set point 2

The temperature of the requested water from the HP unit is calculated through a further two Climatic curves
(Heating/Cooling), or by a Fixed set point.
The second set point (Zone2) Heating should be linked to the heat emitters which requires the highest set point in
Heating mode. Example: fan coil unit.
The second set point (Zone2) Cooling should be linked to the heat emitters which requires the lowest set point in
Cooling mode. Example: Dehumidifier.
Note: The second set point (Zone2) is effective only for space Heating/Cooling.
