Introduction
The TKB75.XX 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...

Features
7-day programmable function for energy-saving operation
On/off control output for heating device
Symbol indicator when heating is on
Mechanical switch key for power supply
Temperature limitation function for protecting the floor (except TKB75.33)
7-day time maintenance in the event of a power failure (model with affix “T”)
Potential-free output for Boiler, Pump, etc...(TKB5.33&TKB75.723T)
Large size LCD display for better readout
“Key-lock” function for protecting the setted parameters (especially suitable for Public places)
