Hi all, I am looking for some advice on dealing with my Tekmar system (used for floor heating in my house) randomly restarting itself. The system (Tekmar house control 403) and the main thermostat (Tekmar thermostat 552) reboots every 2 - 10 minutes. It turns off for just a second, comes back on, and then takes about 30 seconds to read the signals from all thermostats again.
Some additional context:
1. It's hooked up to 7 radiant heat zones
2. As far as I can tell, all of the zones are functional... they can all call for heat okay and they do warm up the house
3. The problem does seem to become a lot more frequent when I adjust the temp on any of the thermostats (i.e., causing it to either start or stop calling for heat)
4. There was this weird error message "Dev Lost 1:20"...which is strange because I don't have 20 devices and none of the thermostats have that address
Pictures are attached.
Thanks in advance!
