Hi TomAli

have same trouble myself with my 03 abbey i tend to set my heater to man 2000w fan as low as pos the higher the fan the colder it blow's, then when van is warm set at 1000w or 500w not a patch on my old 97 omega

ps this is my wife's user name mine's mez8951

This problem is almost always to do with the position of the temperature sensor, (without a remote sensor being fitted), the 'standard' one is behind the temperature dial in the control switch. Problem here is the back of the switch is often above the heater in the wardrobe where the amount of heat in the wardrobe then effects the sensor more than the the vans general temperature.

The 'remote' sensor plugs into the main control box and automatically disconnects the one in the switch, this sensor can then be sited away from direct heat (at floor level) where it can quickly respond to the vans temperature.

One further possible is the remote is fitted but in the wrong place, favourite places can be directly opposite a blown air outlet, underneath a pelmet/shelf or even above the oven!!

Will the caravan manual show the position of the temperature sensor  as i will look into this further.

If this is a common problem Gary, why haven't the caravan makers done something about it do you think? We had our Bailey Monarch back to the dealer four times with the heating problems, just kep getting a "nothing wrong" answer. Seems such an obviously fundamental design flaw.

Common? it's been going on for years, when I read this thread I thought this question is getting more perennial than the butane/propane one!!!! 

To give Truma their due though, it specifically says in the fitting instructions not to fit the control switch with it's back in the way of direct heat,ie the wardrobe, problem then is van manufactures understandably find this same position the easiest.

Foolproof solution is to fit the remote sensor and attach the sensor itself to the gas sides temperature sensor, in this position the fire works perfectly on both sources of heat, it also does not require any drilling or routing of wires   I was under the impression this position had been universally adopted for retro fitting and told Truma were fitting them there on new fires but I must be wrong?

As for £40 for a sensor!! you can buy the bits for less than £1!!! if your then any good with a soldering iron the rest is a doddle.  Bits required 1 x 10k (negative) thermistor, 1 x 3.5mm mono jack plug, 1 metre length of 'speaker' wire  and some 'shrink wrap' tubing to cover and protect the thermistor solder connections.

There is another problem with some earlier fires whereby the main control board is faulty, I didn't mention that as I again thought the problem had been sorted.

Thanks for this thread folks. I've just discovered what the little black widget at ceiling level above the heater is!!!

What muppets, this must the single most stupidist (sp) place for a remote thermostat!
