Cabin Temperature Control - Smith Newton 2000 Series Owner's Manual

8. Cabin Temperature Control

The electric cabin heater and optional air conditioner consume energy
supplied by the traction batteries.
Minimizing the use of these functions maximizes the range.
This vehicle is equipped with an electric cabin heater and an optional electric cabin air
conditioner. Both utilize the vehicle vent system in the dashboard and consume electric
energy supplied by the traction batteries. Be sure both the heater and air conditioner switches
are in the OFF position before starting the vehicle. Once the vehicle is running, you may
operate either system.
NOTE: If both the heater and the air conditioner switches are ON, neither system will function.
Cabin Heater (Figure 8.1)
1. Depress the Heater Switch (blank switch with LED next to the Air Conditioner switch)
on the dash.
2. Set the Fan Blower Speed to the second position, the lowest fan setting. NOTE: It
may take a few minutes for the heater to warm up. Heater will reach full operating
temperature quicker if you do not increase the blower speed past the second position
until warm air is felt coming through the vents.
3. Adjust Mode Control to regulate where the warm air is delivered.
4. To increase heater efficiency, push the Recirculation button so the warm cab air is re-
circulated. When humidity is high, recirculating cab air may cause windows to fog, and
Recirculation button should be off.
5. As the cab warms up, adjust Fan Blower Speed, Temperature, disable
Recirculation, or turn Heater off with dash switch to control cab temperature. Turning
the heater off is the preferred, most energy efficient method, to regulate the
temperature.
