Room temperature overshoots setpoint by several degrees before heating turns off

Safety first: No internal wiring work is required for configuration changes.

Steps to troubleshoot:

• 1. Check sensor placement:
  • Ensure the internal or external room sensor is not near radiators, windows, or drafts.
• 2. Adjust control parameters:
  • Enter the installer menu and look for regulation mode (e.g. PWM, hysteresis).
  • Increase hysteresis slightly or switch to a more stable mode recommended by Heatit for your floor type.
• 3. Use floor sensor limit:
  • Enable floor sensor control and set a reasonable max floor temperature to reduce overshoot.
• 4. Allow learning period:
  • Some Heatit models adapt over time; allow several days of operation after changes.
