8. HEATING – COOLING
The system works in cooling mode with monitoring of the humidity in the rooms, therefore thermostats or sensors with a built-in humidity sensor
must be used. If the humidity (%) in the rooms exceeds the set global maximum value, the cooling to the respective room/zone will be stopped
(the valve closes).
To ensure that there are no problems with moisture/condensation in the oor construction, it is therefore important that the ow temperature
and/or a dewpoint protection can be controlled by the heat pump or cooling unit.
Conguration of the system in cooling operation
Diagram for connection of cooling unit/heat pump
If automatic switching from heating to cooling controlled by the cooling unit is required, a cable must be inserted into the terminal marked
“Two-st. input” and connected to resp. “Cool.” and “+ 5V”. The signal must be a potential-free signal (ie. without current) and be “normal open” by
default. When a signal is given from the cooling unit, the switch will be closed and the Soline system will switch to cooling operation.
If the system consists of both master and extension control units, the cooling signal will be transmitted from master to extension modules.
Setting of heating/cooling mode
Press the MENU button and go to the “Fitters menu” with the arrow keys, conrm with MENU. Go to “Heating - cooling” conrm with MENU, con-
rm “Operation mode” with MENU.
Heating Manual switching for heating in all zones.
Cooling Manual switching for cooling in all zones.
Automatic If this setting is selected, the control unit automatically switches between cooling and heating based on an input from the
heat pump or cooling unit.
Note
We strongly advice to choose “Automatic”, so the switch over is controlled by the heat pump or cooling unit.
