Hi fiona,

if you have the service manual for the unit and if it s accessible, i strongly suggest that you scan the unit's service manual.

once the unit is opened, near the power supply, you should be able to see a 10 / 15amp fuse, if you see it blown or triggered, have this fuse replaced. these kinds of fuse is readily available from a local electronic shop.

the fuse may look like the ones below.

Once these are replaced and still did not give any restart on the unit, please consult the service manual on having the "power supply capacitor" replaced.

regards,

voodoo

I need a new Rehau Thermostat CT for my underfloor heating, the current one is broken. I am located in Leitrim in Ireland.


Give eBay a look, there are several for sell there.
I would ask if they are EU compatible at 50hz. I'm guessing they are since Rehau is a Canadian company but I'd check first.

My radiant floor heating suddenly stopped working. Wall thermostat is functioning normally. GFCI test is working fine. What can I check next?


Monica, There might be a break in the wire mat, you or a electrician will have to check with a digi multi meter.

We have a robbens underfloor heating system with a heatrae electric boiler on a floating floor system. The underflooe heating manifold has a grundfos Alpha + pump. What setting should this be at? Currently...


Venting of the system is when you re circulate the water or cooling fluid in higher speed to eliminate the air bubbles from the system.
If water circulate on a too higher rate does not have time to dissipate the heat so your floor is cold.
You need to go to 2 or even 1 depending on the length of the heating coil in the floor. Unfortunately the pump only has 2 speeds (setting 1 and setting 2) so whoever install your system had to calculate the length of the pipe for maximum efficiency. Try on 2 and if not satisfactory go to setting 1. If too hot on setting 1 then you can adjust the heat by reducing the amount of water from the shut-off volume control. It is a hit and miss situation, I know but unfortunately that is the only choice remaining now after the system is installed.
