Not the kind ive read on wiki or propex brocures
it has 4 screw terminals on it not the 5
the rocker switch is only on or off(2 way) not 3 way
ok the story goes my oldpropex is kanckered currently with propex beign modernised to latest spec

whiel talking to the man at propex i mentioned mine only had 2 wires conected to he told me should be 5 going to my thermostat
So i duly puechased 5 core wire but upon opening the thermostat have foudn it to be seemingly different to the "normal " ones
I have emailed propex man(awaiting a reply) just wondered if anyoen has this style and how i would wire it to a unit thats been moderinsed

Hi
Our Karisma has this type fitted and I've looked at the installation instructions which shows a two way / 4 terminal switched unit for the standard 1600W and a multi position switch for the 1600 / 3000W "purged air" version
Don't know too much about Propex at the moment but it mentions the purged air versions have the ability to run the fan without heating to circulate air in hot conditions
Hope this helps

what's up mate?
is it bust?
it's just a switch ....on....off..
if the temp in the van is warmer than the setting you have chosen then it will switch off the propex...
Mine is the same...
there is no run on facility as you say it's a two way switch
you have an early model that's all
try moving the dial ...does it click?
if not then it's a timer type

OK well mine clicked at the surrounding air temperature.... whether it was on or off... used or not.
mine is a three wire stat but only two are used (on ...off)
no click does not sound well as mine too has died not a click to be heard.
so friend... it seems we are in the same boat

Mine must be a 'purge' version. Not only can it run just as a fan if the weathers hot, but if it's run as a heater and the stat' switches the heater off 'cos the van's warm enough, a minute later it will start to run just the fan on it's own. Presumably to 'purge' the unit of built up heat as it stops after about 20 seconds or so.
