Temperature Controllers
T775 Series 2000 Special Stand-Alone Controllers
The T775 electronic remote temperature controllers are the next
generation of commercial and agricultural controls capable of remote
sensing of 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
