T775U Series 2000 Electronic 
Stand-Alone Controller
PRODUCT DESCRIPTION
The T775 electronic stand-alone controllers are the next 
generation of universal controls capable of remote 
sensing of temperature, humidity, pressure, etc. and 
providing switched and proportional outputs to various 
types of loads. A built-in time clock is standard.
The T775U controller allows a wide range of sensors to 
be configured. Humidity, pressure, temperature, or any 
0-5 Vdc, 0-10 Vdc, or 4-20 mA input is supported.
A Reset function is available where the Sensor B 
temperature (e.g. outside temperature) is used to provide 
reset control for Sensor A (e.g. humidity). For example, 
as the outside temperature gets colder, the setpoint can 
automatically be adjusted to prevent condensation.
IMPORTANT
The T775U is an operating control, not a limit or 
safety control. If used in applications requiring 
safety or limit controls, a separate safety or limit 
control device is required.

For the sensor inputs, Sensor A can be 0-10Vdc, 4-20mA, or a standard temperature input. Sensor B is a standard 
temperature sensor input only. Sensor B is used only for reset on the T775U2006.
