You want the room warmer because your perception of warmth/comfort is different based on the outside temperature and hence heat loss. Which is why a...
D.78 is effective only while the CYL terminals are closed (looped). And yes then, any boiler knob position is ignored and the flow temperature ramps...
1. eBUS can do (atleast) two things. It can vary the required flow temperature and it can fire the boiler. In order to fire the boiler, it needs the...
Just checked this. Like I suspected, the Left hand CYL terminal is 230V Live. And the moment that 230V live reaches the Right hand CYL terminal, the...
You can test this quite easily. I actually think one of the CYL terminal is actually supplying a 230V live and the other terminal is simply there to...
If you have solar panels there is another option. It involves putting the Unvent Cylinder before the combi. But this only works with some combis and...
I recently went through this decision process for a friend and landed back at Evohome. Ofcourse in her case, she wasn't invested in either ecosystem....
When you are controlling the boiler trigger via the Terminal 4, that question becomes irrelevant. The moment there is no 230V on the Terminal 4, the...
Evohome now comes with HW priority, so it will switch off the CH circuit when it switches to a HW heating cycle. OT jumps to a 90C set point when HW...
If you look at your boiler, it comes with a blank face plate. Some installations replace that face plate with a controller for things like scheduling...
If you have any eBUS Thermostats or the additional boiler controller that is plugged into the boiler faceplate, then those need to come out. The VR33...
