digital thermostat (programmable thermostat, floor heating thermostat, radiatorthermostat,touch-screen thermostat) Introduction The TKB80.716 is used for 2-position control with on/off output for the control the temperature by means of an NTC sensor placed externally or internally in the thermostat. The thermostat acquires the actual temperature with its built-in sensor or floor sensor, and the heating contact will close when the room temperature falls below the selected setpoint. Application For the control of warm-water (floor) heating systems and direct electric heating systems used in Commercial buildings, Residential buildings, Light industrial buildings...
