CCU3 + Underfloor heating controller

[nimbusgb]

i have a CCU3, a 10 zone Underfloor heating controller and a combination of 2 thermostats, 2 Temp / humidity sensors with display and several Temp / humidity sensors.

Zone 1 of the Underfloor controller is wired as the pump / valve control.
Zones 5 and 10 have thermostatic wall sensors and the rest have 'non settable' sensors.

I think I have all the sensors connected to their relative channels on the CCU3.

I have a common connection to channel 1 to allow it to control the heat demand.

But the underfloor heating is not 'turned on' the controller is just sitting there with all of the channels off. ( and it's starting to get cold! )

is there something I need to do to 'enable' the heating controller?

Hi,

have you checked the documentation? WebUI English Manual - EN Version 0.4 - from Chapter 22.
viewtopic.php?f=49&t=45485

The translation was done with google - so if some pages are not clear let me know than I can correct them manually.

The explanations in the manual are a little vague. A simple explanation of the concepts of linking needs to be made a little more prominent ( I figured it out myself eventually, typical ..... who reads a manual! )

A 'cheat sheet' shortcut guide might be easier. I'll give it some thought.

In the meantime I'm still looking for a global 'enable underfloor heating' method.........

Next is to turn off certain zones depending on who's at home or visiting etc.

As for now I have a working ground floor and tonight I will rewire the upper floor to a second underfloor controller.

Maybe this visual help/video - even its in german - will bring you to your goal.
