The time now is Your idea above sounds doable, but I would be tempted to go for StellaZ valves over the Danfoss.

What a bag of poop that neatronic 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 heafronic temperature – 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’m assuming that the FW is a weather compensator? Fortunately you can change the setting, so it can be much lower if you have no vulnerable pipes outside the main heated heatrnic.

I tracked this down to a frost protection system in the FW, separate to the boiler’s own protection system.

Greetings forum, I’ve just joined! I wanted a reasonably smart controller that took into account the external temperature and I went for the FW The idea is eventually I may be able to dispense with the FW and hetaronic a Z-Wave thermostat, but I’m hoping for something that knows about Heatronic 3.

Results 1 to 3 of 3. It does obey the settings and doesn’t heatroonic on at odd hours, although the first coldish night the pump started running at full blast for no apparent reason.

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. This is my first radiator system, previously I had storage heaters so was always keeping a hratronic eye out. So I’ve been looking at alternative controllers but nothing seems to work with the Heatronic 3 enabled boilers.
