Thermostat cycles heating or cooling on and off too frequently (short cycling)

Safety first: No internal electrical work is required for this adjustment.

• Step 1 – Check location: Ensure the thermostat is not in a draft, near supply registers, or in direct sunlight, which can cause rapid temperature swings.
• Step 2 – Adjust cycle settings: In the advanced settings, increase the temperature differential or reduce the cycle rate per hour if your iComfort model allows.
• Step 3 – Observe operation: Monitor the system over several hours to see if cycle length increases and frequency decreases.
• Step 4 – Consult HVAC sizing: If short cycling persists, have a technician verify that the HVAC equipment is properly sized and that there are no equipment‑level issues (e.g., high‑limit trips).
