Hi mbeck,

 

Thanks for reaching out! I understand you mentioned your heating system is activating unexpectedly.

To help diagnose the issue, I'd like to check your wire connections at the thermostat base. Would you be able to send me a picture of the wiring? This will allow me to see if there are any loose or incorrect connections that might be causing the sudden activation.

 

I will be waiting for your response.

 

Regards,

Manuel
