Currently there is no Night Set Back feature on the Ideal Halo however, with 6 heating schedules per day there is the flexibility to set additional “on” periods with a lower setpoint to compensate for this.

Frost protection is active when the Halo is set to OFF. It will run the central heating system if the temperature drops to 5°C to prevent freezing.
