230 V circuit description (*00)
All trench heaters need a 230 V / 50 Hz power supply.
Factory-fitted actuators are wired to the terminals. The appropriate terminals are available for valve actuators.
The fan speed of the EC fans used can be continuously variably controlled by a 0-10 V DC signal. The internal motor elec-
