T775 Series 2000 Electronic Stand-Alone
Controllers
DESCRIPTION
The T775 electronic stand-alone controllers are the next
generation of commercial and agricultural controls capable of
remote sensing of temperature and providing switched and/or
proportional outputs to various types of loads.
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 is
required.
FEATURES
• Easy-To-Use Graphical Interface Operating the new
T775 is easy and the intuitive programming will save you
time on every job. Each model includes a keypad lockout.
• NEMA 4X Enclosure Option Certain models are offered
with NEMA 4X enclosures to protect them from water and
corrosion for installations like washdown areas, animal
confinement areas, swimming pools and other similar
locations.
• Internal Time Clock Scheduler The Setback and Disable
Output options, controlled by the built-in scheduler or
digital input, will help save energy during unoccupied times
and give you more control of the equipment without
needing to purchase an additional time clock. Run times
can be displayed for the first 4 relay outputs.
• Up To Two Independent Modulating Outputs Each
output can be individually configured for 0-10 Vdc, 2-10
Vdc, 4-20 mA or Series 90.
• Modulating High Or Low Limit Control To protect your
equipment from freezing or overheating, models offering
this feature give you the ability to adjust your control
temperature at Sensor A to protect equipment at Sensor B.
The control adjusts its modulating output to prevent
exceeding the user-entered High (Heat mode) or Low
(Cool mode) limit for Sensor B.
• Optional Configurable Integral And Derivative Times
Standard on every device, this feature delivers pinpoint (PI
or PID) control on modulating outputs set up by default to
behave just like the previous T775 Series 1000, but now
you can adjust reaction times and behavior, giving you
more control. Anti-integral wind-up is standard.
• Reset Models With Simplified Setup Reset programming
is easy. Simply enter the high and low control temperatures
and the corresponding high and low outdoor temperatures.
As your outside temperature gets colder, the setpoint
temperature automatically adjusts to save energy.
• Configurable Minimum Off Time If needed, setting a
minimum off time can protect equipment and reduce the
need for a separate time delay device.
• Sensor Calibration Calibrate input sensors up to +/-10° F
(+/-6° C) for temperature and up to +/-10% of range for
other sensors (e.g. pressure, humidity) to compensate for
resistance drops in longer sensor wire runs.
• Fewer Models Fourteen T775 models replace 38
Series 1000 models.
• Special Models Four T775 models are available to ensure
your control needs can be met with a single unit for special
applications:
— Universal Model (T775U) to control pressure,
humidity, or any medium with an analog input
— Special Boiler Model (T775P) for boiler control
— Special Staged Sequencing Model (T775L) for
sequence staging of relays with one or two setpoints
— Special Expansion Model (T775S) for staging up to
12 relays with two setpoints
