Allegro Bay Owner's Manual - Tiffin Motorhomes

HEATING & AIR CONDITIONINGis not at fault; simply reset your breakers and/or replace your fuses. Should such conditions continue,one may wish, in turn, to reduce the electrical load (in this case, turn “off” the air conditioning system forawhile) or start the electrical generator.To cool the motor home, the thermostat inside the Allegro Bay is used—thisis the same thermostat which controls the furnace functions (describedearlier). The air-conditioned, cooled air is emitted through the vents whichare located in the roof throughout the entire coach. The discharge and returnair vents run parallel, front to back, on the ceiling. Note that the return ventsare similar to the air conditioning vents. This system allows even distributionfor the returns instead of forcing an excess amount of return air through twosmaller openings. The even return system takes more of the hot air from themotor home, thereby providing cooler air throughout the unit. The airconditioning vents that are mounted on the ceiling are round vent filtersFigure 3-2. RoundVent/Filter(Figure 3-2) that need to be periodically checked for dust accumulation. When dust has accumulated onthe filters, remove them and wash in a mild detergent and warm water.Thermostatic ControlsThe following is a brief overview of how best to use the thermostat (Figure 3-3). For more detailedinstructions, please consult the thermostat literature in the Owner’s Information Package. The thermostatwill have three switches that operate the Fan Mode, Thermostat, and Fan Speed.To operate the Fan mode: There are three levels—Auto, On, and Off.To operate the Thermostat: There are four levels—Cool, Off, Gas Heat,or Electric Heat.To operate the Fan speed: The levels range from low to high. One canmove the setting the level of power desired.Figure 3-3. ThermostatA switch that allows one to increase or decrease the temperature of the coach is also positioned on thethermostat. The user can set an exact temperature with this switch.NOTE: There is an approximate 2-minute time delay after selecting cooling function for refrigerantcompressor to start.NOTE: If the Comfort Control is turned “off” or the thermostat loses power (i.e., power failure), theair-conditioning system will resume operation at the last settings programmed into it when electricalpower is restored.Liquid Propane (LP) TankThe Allegro Bay is equipped with an ASME (American Society of Mechanical Engineers)-approved LPtank (Figure 3-4) which is equipped with an automatic pressure regulator. This tank contains liquid3-4
