Been using the best thermostat e for just over a year. Every so often I get the H153 open therm error. But it's now happening more regularly.
Each time it happened before I checked the wiring and the atag boiler does as have an open therm connection. To correct I need to turn the boiler off and then on.
concerned about the winter months. If we go to visit family and the error occurs then I'm not here to restart the boiler and minimum level of temperature would not then kick in.
Has anyone else experienced this? Extremely frustrating

Hi @Keef_t,
Thank you so much for reaching out. Can you tell me since when you've experienced this issue? Was it since the installation?
11-16-2023 02:15 AM
Yes since installation. As I said the vast majority of the time it works. It just seems to randomly show the error. Recently it has happened more often.
11-16-2023 02:19 AM
Thanks for the info. Are you an installer by any chance?
11-16-2023 02:43 AM
Yes. I followed the self install instructions provided.

In this situation I'd recommend to have a look at the wires to make sure that they are properly fitted at the boiler and Heat Link. As there are 240 V implied I'd definitely recommend an installer to come and have a look.

As per the original message I have checked on the wiring. Assume that since it works 98% of the time that if wiring was faulty it works stop it working all the time. Which is not the case
Could this be a software issue?

In this situation it might be the communication of the heat link with the boiler. As this behavior happens at random times, one thing to check further would be the opentherm connection from the boiler.

Hi there, just checking in with you. Did you manage to check my last message?
11-18-2023 04:09 AM
Yes, the connection appear correct and stable
11-18-2023 04:10 AM
That's great. Did you try also to turn the power off from the boiler and turn it back on? And same for the Heat Link?
11-19-2023 12:42 AM
Yes. I have done that each time the H153 error had occurred

In this situation what I can advise is to have a look at the wires. One of them may be loose or damaged.

Could you please check them on the actual thermostat, not from the app?

Just checked. Shows as open therm
