TRV thermostats open without requesting heat for a back boiler stove

Kevin0005

I have a back boiler stove that heats my radiators and hot water when we use it. - in addition to our burner

Every time I do this, I have to unplug all the TRVs manually.

My friends laugh at me because of this.

Why is there not a mode to open the valves without requesting heat?

This would also help with bleeding radiators and solve many problems for others.

make the rooms zone controller independent and as far as I can tell you’ll get what you want. You’ll have to assign a zone controller again afterwards if you want them to call for heat from the boiler.

I’d concur with Johnny.

Appreciate the reply @johnnyp78.

What do you mean by zone controller independent?

I have every room on a Tado trv with its own schedule.

I have one wall thermostat that is not in use as the radiators request all heat.

Thanks

Okay, think I’ve found it.

So for every room, I have to switch it to independent and then change the temp to open the valves.

Then at the end of the day, go back into every room and change the setting back..

Appreciate the work around, but surely this process can be improved

That’s not the way it should work. With all the Tado trvs set as independent, they act like a time and temperature set dumb trv. Your main Tado wall thermostat, wired or wireless, should call for heat according to the schedule?

Hi Kevin, this is exactly the answer I'm currently trying to find. The Tado rep I'm speaking to doesn't understand what I'm asking, which is frustrating.
Was there a solution to this problem?

Sorry I never replied back on this.

So what I did was set 14 out of 16 thermostats to “Zone Controller” under the Heating Zone section on the devices.

Then set 2 of my thermostat devices to call for heat from the zone controller. An Upstairs and downstairs room.

So when I want the backboiler to run, I can set all rooms to 25 from the app to open them up, except for the 2 that call for heat.

If I want those 2 rooms to get heat as well, I just twist off the thermostats manually.

That’s the best I could come up with.

Only downside is that if my 2 rooms heat up quicker (they rarely do) it will stop heating going to other rooms that didn’t make temperature. So pick slower warming rooms as your call for heat ones.
