Note:
We recommend not to select a value that is too low for parameter P22. In particular,
in cases where cooling loads, such as drafts or open windows, affect the control process,
short cycles usually have a negative effect. The heating is directly switched off after the cool-
ing stops.
Note:
The set points for room temperature entered in TROVIS-VIEW can be reduced or
raised by 5 K at the room panel (F05 - 1).

Changing the operating modes
6.3.1 Switchover via binary input
The controller with electric actuator can be configured to allow one of two active binary in-
puts to determine which operating mode is used. Depending on the configuration, the follow-
ing applies:
Binary input BI1:
F08 - 0
F08 - 1
Open binary input BI1 – Rated operation
Closed binary input BI1 – OFF/Frost protection
Open binary input BI1 – Rated operation
Closed binary input BI1 – Reduced operation
