THERMOSTAT CONTROLS
The following is a brief overview of how best
to use the thermostat (Figure 3-5). For more
detailed instructions, please consult the ther-
mostat literature in the Owner's Information
Package.
1. Use the "Thermostat" switch to select the de-
sired function (e.g., COOL, OFF, GAS HEAT,
or ELEC HEAT).
Note: In the "COOL" mode there will be a
delay of several minutes before the refriger-
ant in the air-conditioning system begins to
cool the motorhome, as the compressor is on
a time-delay circuit and it must also cool the
ductwork to the vents first.
2. Select the Fan Mode operation (AUTO or ON) and the Fan Speed operation (LO or HI) to select fan
speed desired.
3. Press the Up and/or the Down buttons to set the desired temperature for the motorhome.
NOTE: When the fan mode is in AUTO, the fan will cut on and off when the temperature reaches the
desired setting.
When the fan mode is on FAN, it will continue to run even though the compressor cycles on and off
when it reaches the desired temperature.
If the motorhome temporarily loses its 110 power, the air conditioning system will resume operation at
its last programmed setting once power is restored.
If 12v power is lost to the thermostat, it will automatically re-set to 72 degrees once power is restored.
NOTE: There is a thermostat control for each air conditioning unit, one located in the bedroom and
one in the living area.
HEAT PUMP CONTROLS (OPTIONAL)
To activate the heat optional pump, set the thermostat to ELEC HEAT and select desired temperature.
NOTE: If the setting on the thermostat and the room temperature are more than five degrees apart,
the gas furnace will automatically turn ON with the heat pump. Once the room temperature reaches
the desired level specified on the thermostat setting, the furnace will cut off and the heat pump will
maintain the heating of the coach.
NOTE: The heat pump is controlled by the thermostat located in the living area of the motorhome.
If the external temperature falls to 35-38 degrees Fahrenheit, the heat pump will become inoperative
and the gas furnace will begin to operate automatically.

What could be draining our house batteries in our 2015 45LP Allegro Bus when we are plugged into a 50 amp service
Possible causes of house battery drain in a 2015 Tiffin Allegro Bus 45LP while plugged into a 50-amp service include:
1. 12 VDC Loads – Interior lights, water heater, TV switching box, slideouts, power roof vents, and the monitor panel continue to draw power from the house batteries.
2. Inverter Usage – If the inverter is supplying power to appliances, it may be drawing from the batteries.
3. Faulty Converter or Charger – If the converter or battery charger is not functioning properly, the batteries may not be charging while connected to shore power.
4. Battery Disconnect Not Engaged – If the battery disconnect switch is off or malfunctioning, the charging system may not be supplying power to the batteries.
5. Parasitic Draws – Devices like radios, satellite receivers, and personal computers may continue to draw power even when not in use.
6. Battery Condition – Aging or damaged batteries may not hold a charge properly, causing them to drain quickly.
7. Loose or Corroded Connections – Poor electrical connections can prevent proper charging and lead to battery drain.
Checking the converter, inverter, battery connections, and loads on the 12 VDC system would help diagnose the issue.

To adjust the mirrors on a 2015 Tiffin Allegro:
1. Adjust the convex mirrors so that 1/3 of the mirror shows your motorhome and the rest shows vehicles alongside.
2. Adjust the mirrors vertically to improve visibility.
3. Use the mirror adjustment controls to fine-tune the position.
4. Further adjustments can be made at the swivel portion of the mirror arm.
5. The mirrors contain heating elements for defogging or de-icing, controlled by a red "on/off" switch near the adjustment controls.
6. Be aware that objects in convex mirrors appear smaller and farther away than they actually are.
