plus heat in the engine's cooling system to keep the cab warm.
An extra electrically driven water pump pumps the coolant through
the heating system when the engine is off. The cab fan pumps air
into the cab. The pause heater is turned off automatically when the
temperature in the cab is six degrees below the set value on the air
conditioning system. The pause heater is activated with Switch
