The comfort control panel operates the individual components which together create the
motorhomes HVAC (Heating, Ventilation, and Air Conditioner) system.
NOTE: For a detailed description of how to operate and understand the climate control panel,
refer to the Duo-Therm owner’s information.
The heating module uses a diesel burner (12 VDC) controlled
by a multi-functional electronic controller as the primary
source of heating coolant fluid (anti-freeze and water).
Two 1500 Watt, 120 Volt AC immersion elements are used as
secondary heat sources. The heating module heats the
coolant fluid to provide a source of heat for all hydronic space
heating needs. When used with the distribution module and its
integral distribution pumps, the heating module has the ability
to circulate the coolant fluid to all space heating areas.
The 120 Volt power required to operate the Hydronic Water
Heating System may be provided by either connecting the
motorhome to an outside power source when parked or by
use of the motorhome generator.
NOTE: For detailed information regarding the operation and maintenance of the Hydronic
Heating System refer to the manufacturer’s owner’s and operations manual.
