T775A,B,C,D
Remote Temperature Controller
The T775 family of Electronic Remote Tem-
perature Controllers provide on-off temperature
control for ducts, tanks, chillers, heating and re-
frigeration 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 agri-
cultural confinement buildings, storage areas and
heavy industrial applications.
T775A,B
T775C,D
■ 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.
IMPORTANT: The T775 is an operating control, not a
limit or safety control. If used in applications requir-
ing safety or limit controls, a separate safety or limit
control device should be used in conjunction with the
T775.
