In a 2005 Magna, does anyone know about the temp sensor in the service bay and how it helps prevent freeze up.
I understand the sensor is supposed to turn on heat when there is a danger of freeze up in the bay. But to make it work, what source of heat should you have on inside the coach? For hot water we have a switch for "electric" and "diesel". I don't want to use diesel unnecessarily, but I don't want my unwinterized coach to freeze up these last few weeks when it is no longer inside for heated storage as it was all winter.
So - to make this temp sensor work, what should I set inside the coach?
Thanks.

Tom: I'm going to assume you have a Hydrohot system for heat. As I understand the freeze protection sensor (which you can adjust), it is connected directly to the Hydrohot and if it senses the temp set, it automatically turns on the system to distribute heat to the compartments. It would, of course, run on diesel or electric, but only by switching the controls. I would assume if the Hydrohot is powered up and heated, the electric should be sufficient to maintain temp. If the system is cold, electric takes much longer to heat the system to working temp and in that case, it would be more efficient to use the diesel to get the system up to working temp and then use the electric to maintain.

Does anyone know about the temp sensor in the service bay of a 2005 Magna that prevents freeze up?
If the coach is unoccupied and no heat is "turned on" but it is plugged into shore power (either 30 or 50 amp) and the sensor calls for heat in the bay, what is the source of heat?
Normally our Magna is in heated storage during winter and therefore not winterized. But in the late spring we put it outdoors but still have to worry some about cold nights. We have a HydroHot system that heats water and the coach with diesel (electric also used for hot water when plugged into shore power). We don't normally turn on either electric or diesel when in storage.
Question: if the service bay sensor determines freeze up can happen, does the sensor somehow turn on the Hydrohot diesel heat even if we haven't turned it on inside the coach? If plugged into electric power (30 amp is all we have available) does it use electric power to heat the bay?
Any help or suggestions would be appreciated.

The bay heat is from the Aqua hot and you can have it on Elect and when the temp drops to a certain temp then bay heat comes on automatically as it is pre programed it will not heat from another source Denny

Hello Tom
I believe the bay sensor will only turn on a circulation pump that will circulate water from the Hydro-hot to the heat exchanger in the water bay. You have to have either the diesel burn or the electric heat switch turned on in the coach to have hot water to circulate. If both are off, the temp sensor turns on the circulation pump, but just circulates the cold water in the hydro-hot tank.
