2-pipe heating
2-pipe cooling
2-pipe heating/cooling
4-pipe heating + cooling
Selects the fan coil unit (blower convector). The type selected affects the depiction on the web user
interface and the number of valve control values.
• None: A fan coil unit is not used in the room.
• 2-pipe heating: The fan coil unit can only heat
• 2-pipe cooling: The fan coil unit can only cool
• 2-pipe heating/cooling: The fan coil unit can heat and cool. It is only connected via 2 pipes that contain
hot or cold water depending on the central operating type. It is therefore only ever possible to heat or
cool; a central changeover is necessary to change.
• 4-pipe heating + cooling: The fan coil unit can heat and cool. In a 4-pipe system, separate pipes are
used for the hot and cold water supply. It is therefore possible to change between heating and cooling
at any time. As such the room thermostat can select the heating/cooling operating type as required.
