Nuevo Heating

We have recently bought privately a low mileage 2005 Nuevo 2 berth, replacing an older & smaller camper.

We are very pleased by it, but rather baffled by the heating controls. Can anyone explain how they work and how best to use them.

I believe that the Truama heater unit works from both electric & gas. My understanding is that the controls on the control panel showing '500', '1000' and '2000' settings with a rotating thermostat is the electic control whilst n main power. Can this be used in conjunction with gas or only as an alternative.

There is a control on the left of the unot agaon with a thermostat which ignites & controls the gas. This seems straightforward. The control on the right of the unit is for the fan blower operation. Is this better than just convection heat?

Most confusing is the slider on the fan control showing what I think is a lame on the left, 'O' in the middle and 'A' on the right. What is this for.

One other thing - opposite the heater below the 'cocktail cabinet' is a switch labelled 'radio isolation switch'. Any idea what this is for or does.

Although I have a set of instructions for the camper they are not ever so useful.

Any help is much appreciated,

Thanks,

John

The Truma heater can be used on both gas and electric together. The fan controller is o- off, A - auto, fan speed controlled automatically, M - manual control by the rotating switch. Use of fan will distribute heat around the van much quicker and stop overheat.

Radio isolation switch is to switch off radio remotely, AS modified original radio power to work off the Habitation battery rather than the vehicle battery.

I've nothing more to add, all answered expertly by Peter and Ploughlin.

Yep, I agree, Peter has it covered. Just one more thing regarding the water heater thermostat you mentioned, although you can set the water temperature to whatever temperature you like when running the boiler on gas, when using the electric element it heats up to maximum and is not governed by the thermostat.
Al.

your setup is identical to mine (2008 Nuevo) and it the thermostat (part of the 500/1000//2000 knob) is anything like mine set it to max and leave it reducing it even slightly will cause the heating to cut out even if there is frost on the bedding!

Peter is correct in his description of the system on our Nuevos but in practice I do find the electric system a bit problematic.  

After I have warmed the van up on the 2000 watt setting I keep the thermostat high and switch to the 1000 or 500 setting depending on how cold it is outside.

On gas the van is warm on the 4 setting on the gas knob and this seems to stay at a steady temperature inside.

At night on electric I tum the stat to 6 and the switch on 500 and leave the fan off

If it's cold in the morning I set everything to max again turn the fan on and we stay under the duvets til it's warm. 

I always turn the heating back to lower wattage when using the small travel kettle and
cooking ring or toaster as I don't want to trip any fuses. Some you can reset on the outlet but others require the warden.

I've just been in the van to put some heat on as it feels really cold in there. I put switch to 2000 and that worked fine through the fire. I then put fan to A and the blower worked through the vents and the heat through the fire deminished. I left it running for half hour. Going back in, the fan has gone off and heat coming out of the fire. The manual fan switch is working so what's happened to the auto A setting?

I had it on full.

It's been on for about an hour now so just been back in, heat still coming out of heater but fan on A not working. If I put manual fan on, heat immediately stops from heater but blows hot out of vents. Have now put fan to off and turned down wall dial to 1 . Van warm now so expected heat to stop on setting 1 but still chucking it out full. Left it now and check again in 20 mins.

I think I have found the problem. If I press lightly on the fan slide switch, the fan goes off, if I press down in the slot then the fan comes on again. Obviously a poor connection inside the fan switch. Now need to find a way to get at it.

Never had to Peter, so no I don't.

Thanks Peter will try in the next day or so.

This might be of help to someone

That's pretty thorough Rose. I presume Gary5 is Gary from arcsystems of Nottingham.

I thought it might be my hab check engineer who's called Gary and he once gave me a talk on how to get the best from my fire. As normal I've forgotten most of it but I remember him saying keep the fan on low. I will ask again when he comes for the next check.
