The programmable clock thermostat with real-time clock (date and time factory pre-set) allows you to set switching times (up to 6 per day) and temperatures according to personal habits. Three programming modes, 7 days (Monday to Sunday), 5/2 days (Monday to Friday/Saturday to Sunday), and 24 hours (Monday to Sunday), make programming easier. The programmable valve protection prevents the valves or pumps from sticking during the summer months. It is suitable for controlling actuators in underfloor and convector heating systems, oil and gas hot water heating, circulation pumps, heat pumps, and electric heating devices.
