FBox entry
Value Meaning
“
Comfort
”
0
The controller switches directly to Comfort mode.
“
Reduced”
1
The mode can be set to Comfort for a definable period via the
presence key or the communication function (see Function,
setting, control parameter register 0). At the end of this time,
the mode automatically switches back to Reduced operation.
“
Standby”
2
When a presence is detected from the presence key or the
communication function, the controller switches to Comfort
mode. Where no presence is detected, the controller
switches directly back to Standby mode.
“
Permanently
reduced”
5
The controller works permanently in "Reduced" mode.
Presence detection is deactivated. This mode is especially
suitable to maintenance and service activities at times when
the room is not in use. With on-demand systems, this makes
it very easy to prevent the whole installation, including
climate control, from switching on when not required.
“-SetPt “
Active base set point (register 41) for cyclical calculation of control set point. (See
section on "Functionality")
