Ultraheat Problem


DUNCAN123

Recommended Posts

Hi guys, were away for a couple of days and our Ultraheat isnt wanting to play.

Was fine yesterday but this morning is just making an intermitant clicking noise.

The green light at the switch is on and the noise seems to be coming from the unit itself.

 

Any suggestions greatfully recieved.

 

Thanks Duncan

Hi Duncan I remember reading about someone having a similar problem with theirs and it was something to do with a thermostat, now unfortunatly I'm can't remember what forum it was in, maybe you could check through the search area in this forum and when I get back from shops I will try looking in some other forums,unless of course someone clever comes along and reads this very soon.

Sorry I'm no help but good luck

If the ultraheat is clicking but not producing heat, then it will either be the temperature in the van where the thermostat is located has reached the cut off temperature, or the relays on the PCB have failed.

 

Does your ultraheat have a remote sensor fitted? if it does it will be located on the gas temperature sensor at the front right hand side of the fire, attached to the copper temp bulb just behind the fire front.

 

If it does not, where is the control for the ultraheat located?

Just a nice quick thing to try that i have had a few times. Look down the back of the space heater and you should see a grey box which houses the ultraheat pcb on the left hand side there is a remote thermostat lead that looks like a headphone jack plug. Try unplugging it and running the heater to test. I have had faulty stats quite a few times. Takes two seconds and hope this helps Cvan1

Hi cvan1 tried ur suggestion and the ultraheat is working!!

Can i leave this lead unplugged? I take it this means no thermostat control which to be honest isnt a big deal

 

Thanks Duncan

Hi Brecon, the control for the ultraheat sits beside the control for the ultrastore.

Its on a wall beside the main control panel for the pumps and the battery meter.

 

Thanks for the help DaisyMaisy. Duncan

Hi Duncan.

As you have tried the advice about removing the remote jack plug, and the heater now works, your remote has failed.

The reason it was probably fitted is that the wall switch control is in an area whch gets warm, either in a wardrobe wall or near the fridge, and as the thermostat is part of the wall switch, the back gets hot, switches off the heater but takes much longer to cool than the rest of the van.

 

It would be worth getting a new remote sensor which clips to the gas temperature sensor

If indeed unplugging the remote stat has cured it, then I would first think the remote was not fully plugged in, by design it automatically disconnect the original stat as it connects the remote, it works then the same as earphones do when plugged into a radio, infact using exactly the same components. If then both it and the original is left in circuit, this will leave the main electronic control confused to say the least!

 

I do know Truma ones have 'issues', so if it's not one of my remote stats possibly it is faulty, but I still doubt it, there's nothing clever about it and only 'warranty' problems being reported to me have been cured by fully pushing the jack plug home.

It has to pass through a hole in the metal support bracket plus then a hole in the control pcb's plastic box and then fully into the socket, being awkward to get too it is then difficult to get it fully home through that lot!

If it's 'home made' then it's probably using a screw together jack plug, these are physically to big and won't fully locate.

 

Overall, you are far better with a correctly working remote attached to the gas fires temperature sensor.

Glad to be of help. I would not run without a remote thermostat but i would fit the later type truma part that clips to the gas thermostat inside the front casing. Quick to fit and think theyre quite cheap too. Good luck.
