The wiring of a room-by-room temperature control system depends on several
factors and must be planned and carried through carefully by the installer.
The following cross-sections are applicable for the plug-in/clamping connections:
• rigid wire: 0.75 – 1.5 mm²
• flexible wire: 0.75 – 1.5 mm²
• 8 mm insulation stripped off the wire
Installation must only be performed in industrially available switch-
boxes (mounting boxes) according to DIN 49073-1.
Devices with electronic power supply units (e. g. TV sets or high
voltage LED lamps) do not represent ohmic loads. They can generate
inrush currents of up to 100 A. The switching of such consumers
leads to a premature wear of the actuator. In such cases, the use of inrush
current limiters at the switching outputs is recommended.
The circuit the device and the load are connected to must be
safeguarded with a circuit breaker according to EN60898-1 (trig-
gering characteristic B or C, max. 16 A nominal current, min. 6
kA breaking capacity, energy limiting class 3). Installation guidelines ac-
cording to VDE 0100 resp. HD384 or IEC 60364 must be observed. The
circuit breaker must be easily accessible to the user, and must be identified
as disconnect device for the unit.
