Now specify what should be sent when the control is blocked. Set a value greater 0
(=OFF) to receive a basic heating level, e.g. for floor heating.
On release, the control variable follows the rule again.
Cooling control level (1./2. level)
If a cooling control mode is configured, one or two setting sections for the cooling lev-
els are displayed.
In the first stage, cooling is controlled by a PI controller in which either control param-
eters or predetermined applications can be selected.
In the second stage (therefore only ifor 2-stage cooling), cooling is controlled via a PI
or a 2-point-control.
In stage 2, the setpoint deviation between the two levels must also be specified, i.e. be-
yond which setpoint value undershoot the second stage is then added.
PI controller with control parameters:
This setting allows individual input of the parameters for PI control.
Specify the deviation from the set point value which reaches maximum variable value,
i.e. the point at which maximum cooling power is activated.
The reset time shows how quickly the controller responds to deviations from the target
value. In case of a short reset time, the control responds with a fast increase of the con-
trol variable. In case of a long reset time, the control responds somewhat less urgently
and needs longer until the necessary control variable for the target value deviation is
reached.
You should set the time appropriate to the cooling system at this point (observe man-
ufacturer's instructions).
