T775A,B,C,D 

Remote Temperature Controller

APPLICATION

The T775 family of Electronic Remote Temperature 

Controllers provide on-off temperature control for ducts, tanks, 

chillers, heating and refrigeration units, and other applications 

where electronic accuracy in addition to remote sensing is 

desired.

In addition, certain models of the T775 family of controllers 

provide on-off temperature control of heating, cooling, and 

ventilating systems in agricultural confinement buildings, 

storage areas and heavy industrial applications.

IMPORTANT

The T775 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 

should be used in conjunction with the T775.

FEATURES

• T775A models provide staged on-off control with one 

temperature input and one to four relay output stages.

• T775B models provide staged on-off control with two 

temperature inputs and two to four relay output stages.

• T775C models provide staged on-off control with one 

temperature input and four relay output stages.

• T775D models provide staged on-off control with two 

temperature inputs and four relay output stages.

• T775C,D models meet National Electrical Code (Article 

547) requirements for animal confinement buildings.

• Setpoint temperature range is -40° to +220°F (-40° to 

+104°C).

• Ambient temperature range is -30° to +140°F for one 

and two stage models and -30° to +125°F for three and 

four stage models.

• Linear platinum temperature sensor with T775A,B.
• Water-tight linear platinum temperature sensor with 

T775C,D.

• Adjustable temperature range and differential.
• LCD indication for mode and output status.
• Keypad provides ease of programming and operation.
• Accuracy is within +/- 1°F (at nominal operating 

ambient temperature of 77°F and voltage input).

• Stage(s) independently programmed for heating or 

cooling.

• 24/120/240 Vac input voltage.
• Spdt relay outputs.
