(only applicable if unit has automotive style heating)
The RigMaster heating system is fully automatic. A constant comfort zone is
maintained with the temperature selector (see Cabin Controller Operation
–
Page 11). The bunk heating system is a complete stand-alone system that is not
integrated into the vehicle's cooling system. When heat is selected, and the
RigMaster is in operation, the hot coolant flows through the heater core (installed
under the bunk
– see Figure 2).
The heater/air conditioner blower motor (fan) circulates the cab air through the
heater core pushing warm air into the bunk area. The coolant is then re-
circulated back to the RigMaster Unit.
This system is designed to maximize the bunk heating efficiency.
