3.1A 620 Ohm Resistor
Connect 620 Ω resistor
to wires marked
'Temperature Sensor'
Please note – The black wire with blue stripes, with the mini spade terminals ‐ labelled as 'temperature sensor', must
be connected to the 620 Ω resistor which is supplied in the kit. Polarity does not matter. If the resistor is not
connected when using the multi‐controller the error code F94 will appear. Otherwise, if using the dial controller and
the resistor is not connected the error code F06 will occur.
The Air Top 2000STC requires 72‐85 watts, 6‐7 amps during start‐up. The main power connection has to be made at a circuit
designed to sustain this load without any voltage or current draw. Cigar lighter sockets or auxiliary outputs for any other
electronic accessories are not considered adequate for the power supply for the heater.
If any battery management system is used, please contact a Webasto authorised dealer to ensure correct shutdown cycle is
maintained and prevent carbon build up.
