Confirmed Issue:
The Espar heater thermostat displays a "Low Voltage" message on the screen and the Espar heater stops working.
Affected Units:
Vandoit vans with the Eberspaecher Espar heater installed
Issue Explanation:
The Low Voltage message occurs when the incoming voltage for the Espar system is below 10.5v for more than 10 seconds. In your van, that power comes from the Vandoit electrical system.
