Controller number SG 1553/12V 287.962 is compatible with all 12 volt Aqua Hot and Hydro Hot heaters using the Webasto diesel burner. All our controllers are used and have been repaired and thoroughly TESTED, including being run on an Aqua Hot heater. We have re-built over 1000 of them. The cost less than half of a new controller when you return your old, failed, unopened, undamaged, re-build-able core for a $100 refund for a RED, BLACK OR GREEN labeled aluminum controller. The Spheros black plastic controllers are not repairable and therefore not accepted for the refund.
The spring steel bracket can be rather difficult to remove without damaging the case. Hint: use a small screw driver in the notch at either end of the bracket, to spread it over the side of the case. Please keep your bracket.
We are an electronics firm that rebuilds controllers - not an Aqua Hot service center. A trouble shooting manual is available by searching online.
These controllers have a 6 months warranty from the date engraved on the back. Warranty exchange is not available for a controller that has been opened, altered, or a lost/damaged in shipment. We pay for sending a purchased controller to you and ask that you pay the shipping charges for sending a controller back to us.
We prefer sell controllers than to to provide them for testing or when other heater components are the actual problem. An undamaged controller purchased from us may be returned within 14 days for a $125 re-stocking fee. Keeping our controller as a spare is very helpful because heat of the Aqua Hot system is the enemy of these electronic components inside.
We ship controllers via USPS Priority Flat Rate Mail with delivery in 2-3 days to the USA. We also ship to Canada.
