1. Thanks. Thanks for posting photographs and follow-up.
2..Incompatible ECU. May want to dig up OneManVan's and Wasaabi's? Posts on a replacement ECU being incompatible with kur central computer console. Apparently, Westfalia had a custom ECU and a standard replacement Espar ECU is incompatible with our central computer console.
The fact that the previous owner added a new controller and apparently had other work done may suggest an incompatibility issue?
3. Westfalia Central Computer Console Control.
A. Set heater to on and a desired temperature. Heater should turn on/off as appropriate.
At beginning, heater will be on full blast with lots of fan blowing. Once temp is reached, can barely hear the heater as the fan blower just blows a little to maintain temp. When temp stays by itself or cabin gets hot from daylight temps, heater will shutdown. Later, heater will turn on by itself when temps drop.
NOTE: The quiet, low fan blowing, maintaining temperature is very nice BUT is apparently the cause of the heater combustion chamber sooting up. Recommended to have the heater operate on high (like a smaller heater or the on/off three tines program below).
Some posters have had problems where heater does not turn on again once the set temp is reached.
B. Can set up to three times during a 24 hour period for the heater to turn on for a 2 hour period for each time. When works, nice to warm up Westy before getting out of bed. Should work for the next 24 hour period, etc. There are tiny 1, 2, 3, numbers on the display which show which of the three times you've selected to go on.
