Landis & Staefa Division The settings in detail 3. Juli 2008

The deviation of the actual room temperature from the setpoint is measured and taken

into account when controlling the temperature. In this way, account is taken of room

temperature deviations to facilitate more accurate room temperature control. The

authority of deviation is set as a percentage figure. The better the reference room

conditions (correct room temperature, correct mounting location, etc.) the higher the

value can be set.

• Example:

Approx. 60% Good reference room conditions

Approx. 20% Unfavorable reference room

To activate the function, following must be considered:

• A room sensor must be connected

• The ”Room influence“ setting must be between 1 and 99

• There should be no controlled valves in the reference room (mounting location of

the room sensor) (If such valves are installed, they must be set to their fully open

position)

The flow temperature is controlled depending on the room temperature setpoint, the

current room temperature and the progression of the room temperature. For example, a

slight increase of the room temperature causes an immediate drop of the flow

temperature.

To activate the function, following must be considered:

• A room sensor must be connected

• “Room influence“ must be set to 100%

• There should be no controlled valves in the reference room (mounting location of

the room sensor) (If such valves are installed, they must be set to their fully open

position)

Room temperature limitation

Line no. Operating line

932 Room temperature limitation

The “Room temperature limitation” function makes it possible to deactivate the cooling

circuit pump if the room temperature falls by more than the preset difference below the

effective room temperature setpoint (with summer compensation, 920).

The heating circuit pump will be activated again as soon as the room temperature

returns to a level below the current room temperature setpoint.

During the time the “Room temperature limitation“ function is active, no cooling request

is sent to the source.

The function is deactivated in the following situations:

• Room sensor not installed

• “Room temperature limitation“ = ---

• "Room influence“ (928) = --- (pure weather compensation)
