    How to test if UFH controller is functioning

    Regarding the fuse. Apparently the glass fuse I had put into it blew without me noticing. Really weird. So I replaced the fuse with a ceramic one (damned they are expensive). With the cermamic fuse in place I could measure 223 volts on the thermostat when I put the probes on connector slot 1 and...

    How to test if UFH controller is functioning

    I'll check that out if still relevant after the following Now we have a possible problem. There is but 1 volt measured when I hook up the fluke in VAC mode directly to the thermostat terminals. I have the other mmeter in amp modes in between the valve and it draws no amps at all. But that could...

    yes the valve draws 230 volts. I checked that earlier as well ahh ok sorry misread you. let me read again

    How to test if UFH controller is functioning

    yes, when I tested the fuse using the fluke in ohm/resistance mode I can hear it beep. That indicates there is a closed circuit great, I will let you know in a bit once I am back in the garage Yeah when I hook the valve directly to the ac power I can see it is drawing current. I have used the...

    I,ve been using the fluke in resistance mode to listen if the circuit is closable

    How to test if UFH controller is functioning

    :) haha not really no. This thing has not worked for me and need to be sure before I send it back. Anyway I am 100% sure that the valves/actuators are correct as is the thermostat. I just need to be able to know for certain that it is broken before I send it back and they get upset with me ;)

    How to test if UFH controller is functioning

    If I am not mistaken the thermostat is already connected to (8(connection for thermostat)) in the manual. And 10 (connection for actuators) is now in the correct zone but still no joy ;(

    How to test if UFH controller is functioning

    Also when turning on the AC I do not measure any voltage, while the thermostat is closed, on the 1 and 2 thermostat terminals.

    How to test if UFH controller is functioning

    The unit is a 230 V model as are the rest of the components. I have the valve connected to HZ6 now but with the AC off I still am unable to measure anything when putting the probes on the valve or thermostat terminals. Please see attached image.

    lol, exactly the same it seems ;) The unit is this one https://www.oeg.net/terminal-strip-230v-for-heating-and-cooling-of-up-to-10-zones-211211452 And it's data sheet can be found here...

    How to test if UFH controller is functioning

    Yes it's a new install and it never worked. i do not have heating elements attached. Only a pump, which, (when AC power is connected) is getting power, a valve, which is never getting power and a thermostat. The pump is connected using the orange cable with the alligator clips. The white cable...

    How to test if UFH controller is functioning

    Thank you for your response. I am not sure I follow though. The way it should work I think is that if the thermostat is in a closed state it completes the circuit that is exposed via the HZ L and N terminals. In the image I posted the thermostat is currently connected to the HZ 6 L and N...

    How to test if UFH controller is functioning

    I have an OEG underfloor heating controller that does not seem to do what it needs to do. I am really new to electronics but I'd like to learn. The thermostat is connected to HZ 6 (Heating zone 6). When the controller is not connected to a power outlet should I be able to measure resistance...
