Installation and operating instructions
There is no fault signal contact in fan types 44xx33, 44xx34 and
45xx34. In the event of a fan fault or power failure at the unit
heater, this is not reported via the KaControl system and the
red LED does not light up!
Switch the unit on and off via the control input.
Do not switch the unit on and off via the mains power supply.
KaControl system
Please refer to the KaControl installation instructions for unit
heater I438 for information on the KaControl system.
Voltage supply and fuse
The fan and KaControl module are together supplied by
1 supply line with 230 V/ 50Hz voltage. An LED operating
indicator is positioned on the connecting board in the
KaControl module. A unit fuse Ø5x20 mm is also installed on
the primary side for the control voltage on the connecting
board as well as on the secondary side for 24 V voltage and a
unit fuse Ø5x20 mm on the KathermBoard. Refer to Table 10
for values. Maximum on-site fuse 16 A.
