General

Thank you for choosing Webasto to meet your heating needs. The Webasto SmarTemp Control 2.0
enables you to quickly and effortlessly operate Webasto air heaters specified in the compatibility section.

Operation

The Webasto SmarTemp Control 2.0 is the next generation of the SmarTemp series controllers. It’s
operated using a single rotary dial around the outside of the unit to scroll through menu options. Simply
click the select button ( ) to make your choice.

Compatibility

AT 2000 ST/C - Adapter harness (P/N: 5010612)
AT EVO 3900/5500 & EVO 40/55 - Adapter harness (P/N: 5012138)

Mounting Procedure

Multiple factors such as doors and windows must be taken into consideration as they can directly affect
the SmarTemp Controls ambient temperature reading. Refer to “Temperature Calibration” section on
page 2 if these obstacles are unavoidable.

1. Find a suitable mounting location (on a flat surface if possible) in a visible area.

CAUTION: Always install the unit in an area protected from the effects of weather and dust
contamination or the unit will not function as intended.

2. Use the drilling dimensions / template in the back of this manual to lightly mark the two mounting

holes.

3. (Optional Step) To route wire harness through the mounting surface, drill a 22mm hole as

notated on the drilling dimensions / template.
Note: Always make sure there are no obstacles behind the mounting location prior to drilling.

4. Secure the Webasto SmarTemp Control 2.0 using the two supplied #4 screws.

Electrical Connections

This is a plug and play kit for an AT 2000 ST/C, EVO AT
3900/5500, or EVO AT 40/55 Heater. Refer to the compatibility
section for adapter part numbers.

Duration allows for the selection of continuous heater operation or
timed operation (30 minutes – 14 hours in 30 minute increments).

IMPORTANT: Timed duration is not to be mistaken for Timer
functionality. The duration times above are used when turning the
heater on manually. I.e. set the heater duration for 8 hours before
heading to bed.

Note: If timed operation is selected 10 hours is default.
LVD “Low Voltage Disconnect” allows the user to set the battery

voltage level at which the Webasto SmarTemp Control 2.0 will shut
down the heater. A warning (LED and message) will appear after 8
minutes of low voltage. The warning will remain on for 2 minutes
before the heater is shut off.

If battery voltage is equal to or less than the threshold selected
+0.1v, the heater will not start. I.e. if an 11.5v threshold is selected
the heater cannot be started until B+ has reached 11.7v.
