Manufacturer part number:




Honeywell T775L Temperature Controller, Electronic, 1 - 150 deg F Differential, 1097 Ohm PTC at 77 deg F Sensor, +/- 1 deg F at 77 deg F Accuracy, Relay Output, 4 SPDT Switch, 1/4 Inch Dia x 2 Inch L Bulb, 24/120/240 VAC, 50/60 Hz, Digital Display, Horizontal/Vertical Mount, NEMA 1, Gray, 8-5/32 Inch L x 4-13/32 Inch W x 2-15/16 Inch D, Includes: 50021579-001 Sensor
  • Special boiler model (T775P) for boiler control
  • Universal model (T775U) can control pressure humidity, or any variable analog input
  • Special staged sequencing model (T775L) for sequence staging of relays with one or two set points
  • Special expansion model (T775S) for staging up to 12 relays with two set points (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 set points
  • Support for digital output alarm on the T775P configurable based on minimum, maximum, or differential temperature
  • Set point temperature range: -40 to 248 deg F
  • Throttling range: 1 - 150 deg F

Standard/Approvals: CE Certified, UL Listed

Application: Commercial and Agricultural
