T775J
Electronic Remote Temperature Controller
FEATURES
T775 model provides reset control with two
temperature inputs and one of either 4 to 20 mA, 0 to
18 Vdc, or Electronic Series 90
a
Proportional + Integral
modulating output with 0 or 1 relay output stages, or 1
or 2 relay output stages with no modulation.
-40°F to +220°F (-40°C to +105°C) setpoint temperature
range.
-45°F to +225°F (-43°C to +107°C) sensor display
range.
-30°F to + 140°F (-34°C to +60°C) ambient temperature
range.
Linear platinum temperature sensor.
Adjustable temperature range and differential.
Adjustable throttling range of 2° to 30° F or C.
Adjustable reset ratio.
Liquid crystal display (LCD) indication for mode and
output status.
Keypad provides ease of programming and
operation.
Accuracy is within +/- 1°F/C at nominal input voltage,
nominal sensor ambient temperature (77°F (25°C)
operating ambient). Accuracy can vary as parameters
deviate from nominal.
Stages independently programmed for heating or
cooling.
24/120/240 Vac voltage inputs.
Spdt relay outputs.
IMPORTANT
The T775 is an operating control, not a limit or safety
control. When used in applications requiring safety
or limit controls, use a separate safety or limit control
device in conjunction with the T775.
a
The Electronic Series 90 output provided with T775J
models will not drive electromechanical Series 90 slidewire
devices.
GENERAL
The T775J family of electronic remote temperature controllers
provides reset control for chillers, heating and cooling
systems, and other applications where electronic accuracy in
addition to remote sensing is desired.
