The Honeywell Home ST9100C is a single‑channel time switch designed for precise control of a combi boiler or a single heating zone. Versatile in its application, it supports mains, low‑voltage, and potential‑free switching, making it suitable for a wide range of heating system configurations
The ST9100C features Honeywell Home’s innovative Line of Text (LoT) display, providing clear, plain English guidance whenever a button or slider is used, making day to day operation exceptionally intuitive. It automatically adjusts between summer and winter time and offers up to three timed events per day, giving users flexible control over their heating schedule. Both temporary and permanent override options are available for moments when plans change.
Built for reliability, the unit operates on a 230V AC 50Hz supply with a power consumption of just 10W and performs effectively within an operating temperature range of 0 to 40°C. It also conforms to EN60730‑2‑7 standards and includes a large backlit display for improved visibility. The ST9100C comes with a one year guarantee, providing added peace of mind.
