    Hi.

    I've just picked up our first motorhome and have a real newbie question!

    I have a control like the one shown in the photo, what does this do? I'm assuming this might be a heating system? Is it an alternative to using the gas heating? I've turned it on and all it does is blow cold air out. Some advice would be really helpful as I'm not having much luck! Thanks :)

    Looks like a fan control for the blown air heating.

    It looks like the control for the blown air heating...
    Once you have the gas fire on and running this will blow air around the van through vent holes that you will find.. With no fire on you will of course get cold air as you have found out..:Wink:

    Be aware these blowers take a bit of power, maybe a couple of amps..

    Had a similar setup in last van (Autotrail) but it was built into the gas fire.

    The knob with the numbers is a thermostat, like a heating system at home, 1 cool - 5 hottest. If you push the switch to the top position the fans will blow non stop if switched to the A (AUTO) position then they are controlled by the thermostat and when your area gets to the temp you set (1-5) they will stop until the temp drops.

    You may be able to run your fire/blown air heating on 240v as well as gas, depends on the model.

    Hope that helps:thumb:

    Nearly correct but the dial is not a thermostat its a fan speed control for when the manual position is selected (switch up). This is the older style of blown air unit as fitted to the convector model of heater, now called the 3002. Later models have the control built into the fire surround top plate.
