IR-683 Weekly Digital Programmable Thermostat 

The IR-683 is the new weekly digital programmable thermostat branded IRRADIO. Simple to use and highly versatile, it is suitable for temperature control of devices with a two-wire activation contact (wall-mounted boilers, diesel burners, etc.). It combines practical functionality with an elegant square-shaped design, in white with smooth surfaces to the touch. Equipped with a large display with blue backlighting and a keyboard on the lower front part, it also features a thermal sensor centred on the lower edge and a rear mounting bracket with comb contacts, screw terminals, and a double fixing hole for anchors with XY adjustment. It can be installed with cables in ducting, either recessed or surface-mounted. Battery operation allows installation even in locations without mains connection.
