Truma remote sensor socket location?

[Len_Cuff]

Going to fit a remote sensor to my Truma ultraheat but with a mirror and a torch)) I still can't see where it connects/plugs into? I can see the grey/white box where all the electrics/cables go in but I can't see anywhere where a 3.5mm jack would plug in?

As you look down on top of the plastic box at the back of the fire, on the left hand end in the side, towards the front edge of the box is a recessed jack socket through a pre drilled hole which you are looking for

any chance of any picccies?

When you say near the front of the box, do you mean nearest the fire? Still can't seem to find the socket!!

Hi Len
i had same problem, if you have drawers above the fire take them out to gain access to rear of fire, its pretty dark but if you put your hand right down behind the fire you will feel a plastic control box, it feels like its on the floor of the van, on the left hand side of the box there is a small jack socket on the side of the box its a bit fidelly but with some determination you will feel it with your fingers. the instruction i had says you should route the cable around the back of the fire and bring sensor out of the right hand side but the cable is not long enough so routed it through the left hand side next to the heating ducts and fastened to the gas therostat, i have to say i notice quite a difference, i find the van gets way to hot now where as before it would go cold at night, hope this helps Len.

John, Many thanks, I think I've found it at last, assuming you mean left hand side as you are looking at the fire? Almost at the front of the plastic box through a metal plate which has a hole in it? I am going to fit the FFC so I can locate it up at a better height as it comes with 3M of cable and I have some wooden panels I can easily remove above to feed it through. Anything to get it away from under the bed!!

Hi Len
yes you have got it, they say that the best place to put it is the same place as the gas thermostat at the front of the fire as this is where the cool air from outside is drawn in from under the van, anywhere is going to be better than the bed box as this has to be one of the warmest places in the van.

 

[Len_Cuff]

John, Many thanks. Son used the van a couple of weeks ago and went to Filey. Cold at night BUT heating/thermostat decided it was 30 so wouldn't switch on for long!! What a daft place to put it in the first place He ended up having to use an electric standalone heater!!

 

[Len_Cuff]

Found a mono jack today so thought I'd try it to make sure I have the right place Still couldn't plug it in until I realised that the actual cover on the jack plug was too big for the hole!! Took the cover off and it plugs in fine and isolates the thermostat fitted under the bid Just need to get the FFC fitted now once it arrives. Hopefully the Truma jack will have a small enough cover to fit!!

 

[johnandrew70]

Glad you found it ok Len. where abouts are you going to put the new sensor?

 

[Len_Cuff]

John, Thinking of putting it in the side of the cupboard above the fire around shoulder height as there is a small boxed area where the vent goes up to the roof and I can get into that very easily to feed the cable up so it isn't visible. Looking at the FFC sensor it looks like it simply 'plugs' into a small hole and just the small round front is visible - about the size of a small button.

 

[johnandrew70]

i know what you mean but remember heat rises. i have heard a few people say they have put the sensor near the door, my guessing is that when the door is opened the cool draught makes the heater come on. the one i bought came with instructions and they recommended putting it where i said as there is a vent in the floor. you can always move it if its no better. let me know how you get on.

 

[Len_Cuff]

I assume you can remove the front lower panel to get at the gas sensor then? How's it come off?
Also now discovered that there are 2 different sensors There is the one you fitted (FY1) and the one I've got which is the FFC. The FY1 is fitted in the heater itself whereas the FFC is recommended to go at shoulder height - or by the door as you suggest. Comes with about 3M of cable so it can go anywhere provided I can hide the cable

Hi Len
sorry i havent replied sooner back to work today after having 11 days off

the whole cover comes off the heater quite easily, if memory serves me correct 4 spring clips, 2 each side that are attached to the carcase of the unit that its attached to with slots on the rear of the heater cover.i beleive you pull the cover towards you then up gently,
i think there are instructions on the internet somewhere on how to remove the cover. i will search google and see what i can find.

 

[johnandrew70]

Hi Len
the link below will take you to a page on truma's website where there is a video on how to remove the cover. hope this helps.

I had this sensor standard fit to my old 2004 senator Vermont, end shower.
The sensor was fitted near the bay window, in the corner at top cupboard height.
Never had any problems with it.
If i was you, before fitting it permanently, try it in different locations.

 

[johnandrew70]

Very good advice Ray.

 

[Len_Cuff]

Agree, very good advice so will try the new sensor once it arrives it a few places before I start to get the drill out

 

[Len_Cuff]

Sensor came today. Connected (after first checking what the 'internal' sensor was saying) and there is about a 10 degree difference
Hung the new sensor by the door and it seems to make a BIG difference. Going to test it in a few locations before I get the drill out
