App logic under limit cases
Hi everyone.
I just installed the TVRs in all of my house's 5 radiators, toghether with the Tado X Thermostat. I have a normal boiler (Ariston Clas HE), and I live in Italy.
I'm new to smart thermostats and TRVs, but I find incredibly problematic the behaviour I just discovered:
- Using the app function "BOOST" which opens all of the TRVs at once and also the Tado Thermostat everything runs fine until the system reverts to its original state. At this point, ALL of the TRVs close at once, while the thermostat remains active for a few minutes. In this condition the boiler finds the hot water in the circuit and starts to overheat, becase water can't flow anymore since the TRVs are already closed. The result is that the boiler blocks to prevent damage. Are you serious TADO???
- And what happens if the thermostat is requiring heat but all of the TRVs are closed because they're already at the target set temperature? Didn't try this yet, but I suspect the boiler tries to flow again but the circuit is blocked, so again another block of the boiler?!? Unless this limit condition is managed in the Tado algorithm.
It would just need a time which makes the TRVs closing after a few minutes the boiler is OFF. It's so simple yet no one of the devs thought about that???
Please can someone help me? Thank you

It’s fairly standard to design and build heating systems with an automatic or manual bypass loop in place (where the boiler lacks it).
The kind of pump overrun you mention is normal.

Ok, that's fair. But since it's a smart system I would expect to be really smart.. I'm a software developer, it's a line of code to add under specific circumstances, for those who don't have a manual or automatic bypass..

I think it’s more a marketing term.

Yes and no. I mean, If you market a product in a specific way, then users expect to be that way. Just also see at the way they handled with the pre-heat feature which is still not available on Tado X.. users get disappointed and don't return to the product next time.. and probably I'll do that if the situation isn't going to get better0
