Notes
Safety
CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
● Observe national provisions and comply with the appropriate safety regulations.
Engineering
Identification
Each device has a unique serial number to ensure efficient commissioning. It is provided on the
adhesive barcode label. The serial number can be read directly into the engineering tool using a
barcode reader.
Wiring
Wiring must be sufficiently insulated to the available rated voltage. Sizing and fusing of the wiring
depends on the connected load.
Triac outputs AC 24 V
Individual triac outputs may have a max. load of 12 VA, 24 V*0.5 A=12 VA. The following
possibilities are permitted:
● Slow floating control actuators.
● Multiple motorized actuators with a total of max. 12 VA.
● 1 thermal actuator with 6 VA start load in a cold state.
● 2 thermal actuators with 12 VA start load each in a cold state.
For transformer design (voltage drop), each thermal actuator must be counted at the full start
load, since the triac outputs can be freely controlled.
The heating sequence and cooling sequence are not normally active at the same time
(Exception: Downdraft compensation).
The sum total of the base load, bus power, field supply, and triacs will not exceed 66 VA at AC
24 V.
