Annex 4: Electrical wiring diagrams of heaters
Heater can also be started with vehicle alarm wires in two ways:
• If brown and white wires are connected to an impulse relay (with an impulse
between 1-3 seconds), heater will work on previously set work mode for two hours.
• When brown and white wire is connected continuously (for example, using a
rocker switch) heater will work on previously set work mode as long as these wires
are connected (i.e. rocker switch is on).
