FCC/S 1.X.X.1 | 2CDC 508 200 D0211 Rev A 184
Heating controller:
•
If the actual temperature is below the lower switching point, the controller switches on.
•
If the actual temperature is above the upper switching point, the controller switches off.
Cooling controller:
•
If the actual temperature is below the lower switching point, the controller switches off.
•
If the actual temperature is above the upper switching point, the controller switches on.

Dependent Parameter
Send control value cyclically (0 = cyclical sending disabled)
This parameter is only visible on the selection of the
PI continuous (0…100 %)
or
PI continuous
(0...100 %) for Fan Coil
option.
Options:
0…15…60
This parameter is used to specify the cycle time with which the control value is to be sent.
On the selection of the value 0, cyclic sending is deactivated.

—
Dependent Parameter
Activate temperature limitation
Options:
No
Yes
A controller limit temperature can be activated using this parameter. Using the limit temperature,
the controller's control value for this stage can be set to 0 on reaching a parameterized tempera-
ture. In this way, exceeding (heating) or dropping below (cooling) this temperature can be pre-
vented.
An example of the usage of the limit temperature is floor heating, where exceeding a specific tem-
perature must be prevented to protect the material of the floor.
•
No
: The limit temperature is deactivated.
•
Yes
: The limit temperature is activated. The following dependent parameters are also dis-
played.

Dependent Parameter
Limit temperature
Options:
20…30…50
The value set here specifies the limit temperature that is not allowed to be exceeded (heating) or
dropped below (cooling). If the temperature reaches this value, the control value is immediately set
to 0.
The value set here is compared with the value received via a group object or via one of the physi-
cal device inputs (depending on the option selected, in the
Input for temperature limit sensor
pa-
rameter).
