What it is
The C-Stat 17-B is a battery-powered, 7-day programmable room thermostat from Horstmann (Secure). It lets the user set separate heating (and hot water) schedules for each day of the week, and controls when the system switches on to maintain the target room temperature.
Signs this part needs replacing
- Display is blank, faint or fails to respond to buttons
- Room temperature no longer matches the programmed setting
- Programme resets or loses its schedule repeatedly
- Heating fails to switch on or off at the set times
Before you order
- Try fresh batteries first, as this often resolves display or control faults
- Match the part number printed on your existing thermostat
- Confirm your system is a volt-free switching type before fitting
