Anyway, while I was waiting for my account to be enabled I was doing some more research and am now thinking about a Z-Wave based controller driven from my NAS box to control some wireless TRVs.

Worcester Bosch Heatronic 3 – FW controller

The StellaZ don’t have local control or display, but do report the temperature and react quicker to commands. Fortunately you can change the setting, so it can be much lower if you have no vulnerable pipes outside the main heated building.

Or refusing to come on at all, even though the house felt chilly. It does obey the settings and doesn’t come on at odd hours, although the first coldish night the pump started running at full blast for no apparent reason. I’m assuming that the FW is a weather compensator?

Greetings forum, I’ve just joined! This is my first radiator system, previously I had heahronic heaters so was always keeping a weather eye out. It did take quite a lot of tweaking and a long phonecall with WB support people to get a useful setup. I tracked this down to a frost protection system in the FW, separate to the boiler’s own protection system.

Your idea above sounds doable, but I would be tempted to go for Heatromic valves over the Danfoss. Worcester Bosch Heatronic 3 – FW controller. What a bag of poop that was: Martyn Wendon Vesternet Check out my Blog! Tags for this Thread danfossheatronicopenremoteworcester boschz-wave.

Results 1 to 3 of 3. Thanks for the tip about using StellaZ, I’ll look into that. I wanted a reasonably smart controller that took into account the external temperature and I went hetronic the FW They also react quite slowly to changes – you adjust the setpoint temperature and the Danfoss will s-l-o-w-l-y adjust itself to that heatronci – this might be a consideration if you want to be able to react quickly, for example shutting off a radiator when a door or window is opened.


I understand the principle of weather compensators and I heatroonic with it for a couple of months before finally removing it and re-fitting my previous solution: They said the default settings are designed for a typical German home, but since it was purchased in the UK you’d have thought they would have loaded different defaults.

Yes, the weather compensator. The idea is eventually I may be able to dispense with the FW and have a Z-Wave thermostat, but I’m hoping for something that knows about Heatronic 3.

I’d be very interested to hear any thoughts and experiences others have had in this area. So I’ve been looking at alternative controllers but nothing seems to work with the Heatronic 3 enabled boilers.

The time now is I was attracted to the Danfoss because it has a standalone display and control in case my plans go awry.
