New Coach on the Road Home

[Denny]

Lloyd,

On my 99 Country Coach, the Central Heat Control is for the bay heaters and there is a separate thermostat in the plumbing bay behind a removable panel. This controls the bay heat for winter use.

The Interior Heat Exchangers controls the coach heat. On my bus there are individual Heat Exchanger panel buttons in the front above the pass. side, one in the galley and another in the bedroom. If you push these switches in, they change color and give a different fan speed. These are two speed fan motors.

The temp is controlled by the thermostat setting when on the Furnace mode.

Thermostat must be on Furnace mode and the Interior Heat Exchanger and Central Heat Control buttons above the driver's seat on for Webasto to work to give heat up and down.

Boy, I've been reading these posts and my head is spinning. Maybe someone should call Llloyd and walk him thru his switches.

Gary: He is probably at the best place he can be to get help. He is at Jon's Place.

Jon solved the Battery Balance problem and stopped the leaking water pumps by replacing them.

I found the basement thermostat in the plumbing bay. I am able to turn on the Webasto now and will try the fans tomorrow when we are out of Jon's garage.

Denny thanks for explaining the central heat control.

I think the procedure for starting the living and bedroom heat is:

1. Turn on the Interior Heat Exchanger
2. Turn the thermostat to the desired temperature in the living or bedroom
3. Switch on the living or bedroom ac switch
4. Wait for the "heater on" light
5. turn on the blower speed
6. hope that heat begins to blow out of the vents.

Is this correct?

Does seem overly complicated to me. But then again I am still a newbie and used to radiant heat at the house.

One day we can have a radiant heat in our next bus.

The coach is 1991 Country Coach. Thanks everyone.

We have heat from the webasto.

I just realized that the heat comes out of a different set of vents from the CC AC. Foolish me to think they would use the same ducting.

I am going to need an illustrated map to figure out how to turn on all the different systems. At least it will make it easier for the next owner.

Thank you everyone for walking me through the options.

Lloyd, glad you got it working, but I believe there is a small problem in your list below.

I think the procedure for starting the living and bedroom heat is:

1. Turn on the Interior Heat Exchanger
2. Turn the thermostat to the desired temperature in the living or bedroom
3. Switch on the living or bedroom ac switch
4. Wait for the "heater on" light
5. turn on the blower speed
6. hope that heat begins to blow out of the vents.

Here's what I believe works for your era coach:

1. Turn on central heat control - that is the master switch for the whole system.
2. Turn on the heat exchanger for the zone you want to heat.
3. Adjust thermostat to desired temp

You should not need to turn on the A/C stuff, that is completely separate animal. Nor do I believe there are any blower controls for the heating system. The blower controls are A/C specific.

So, it should be easier than you've indicated! Also note you don't need to wait for red light. The light will come on when the heater turns on, as required by the thermostat.

Lloyd and Pamela are two fine folks that are a great addition to this collection of whackos. He has shared his plans for travel in the coach with us and it is great to know he is going to make the coach a big part of their lives.

Thank you. It seems to be working great now.
