Part 4: Installation and Start-up Installation
55
Note for installation in connection with digital room
device
When installing a digital room device, the heating circuit-
specific set values are adjusted at the room device. These
values are automatically faded out inside the controller.
! If during operation the digital room device is
separated from the BUS for a longer time period
(> 5 min), the heating controller will continue to work
with its own set values.
In order to avoid damages in case of errors - for deviations
from relevant set values (such as maximum flow tempera-
ture for floor heaters) - we suggest the following proce-
dure:
1. Installing the new heating controller
2. Set all values for heating controller
3. Install one digital room device
4. Set all values for digital room device
