Programmable Digital Thermostat for Heating without WiFi

TEMPERATURE CONTROL. Set your heating to between 41°F and 95°F with an accuracy of ±0.41°F. Manual mode allows you to directly increase or decrease the setpoint, while automatic operation adjusts the temperature according to the configured periods. PROGRAMMING AND SETTINGS. Enjoy 6 preset weekday time slots and 2 weekend ranges, with selectable temperature for each period. Anti-freeze, locking, hysteresis adjustable from 0.5 to 4.5 °C and probe compensation complete the configuration possibilities. SIMPLE EVERYDAY READING. The large LCD display displays the measured temperature and the selected temperature at the same time. Its backlight activates by pressing the buttons for easy viewing. WiFi free operation prevents the use of an app or internet connection. 2 WIRE CONNECTION. For a compatible boiler, the connection takes place on the NO and COM terminals. Never connect the phase and neutral mains wires to the thermostat, otherwise the appliance will be damaged.

The 400-TC is supplied with dowels and screws for wall mounting. 2 x AA batteries required for operation are not included.
