10.7 Select the remote control
Under this menu item, it can be determined whether a remote control
will be installed for the heating circuit concerned. Here you can select
the following:
•
No remote control
•
Remote control with display (Programmer) "MEC heat. circ."
•
Remote control without display (BFU or BFU/F)
A remote control unit must be installed to enable the following functions,
which monitor the room temperature:
•
Night setback with hold room temperature
•
Max. room influence
•
Automatic adaptation
•
Optimisation
•
