Thermostat frequently overshoots the set temperature, making the room too warm.

Safety first: No mains work is required.

Steps to check:

• Adjust cycle rate: In the installer menu, set the cycle rate appropriate to your system (e.g. higher cycles per hour for radiators, lower for underfloor).
• Relocate thermostat: Move the thermostat to a representative room with average temperature and good air circulation.
• Check setback temperatures: Avoid large jumps between setback and comfort temperatures, which can cause overshoot.

Resolution: If overshoot persists despite correct settings and location, consider replacing the thermostat with a model offering more advanced control algorithms or consult Salus for firmware updates.
