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.
