T775 electronic remote temperature controller, is the next generation in commercial/agricultural control - capable of remote sensing temperature, humidity, pressure, etc., and providing switched and/or proportional outputs to various types of loads.


  • Universal model (T775U) can control pressure, humidity, or any variable analog input.
  • Special boiler model (T775P) for boiler control.
  • Special Staged Sequencing Model (T775L) for sequence staging of relays with one or two setpoints.
  • Special Expansion Model (T775S) for staging up to 12 relays with two setpoints (each T775S provides 4 relays).
  • Save time on installations with the easy-to-use graphical Interface, large display, and the intuitive programming.
  • Use the time clock scheduler or digital input to control the setback and disable output options to help save energy.
  • Provide very fast or very fast response times on modulating outputs by adjusting the integral and derivative times (PI or PID).
  • Configure models with reset in a few easy steps.
  • Eliminate the need for a separate time delay device and protect equipment with the minimum off time option.
  • Use the T775L and T775P to stage up to 12 relays (with optional T775S) from two independent heat or cool setpoints.
  • Support for digital output alarm on the T775P configurable based on minimum, maximum, or differential temperature.
