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 or Low 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 program-

ming is easy. Simply enter the high and low control temper-

atures 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.

• Special Models Five T775 models are available for

special applications:

—Universal Models (T775U2006 and T775U2016) 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

fThe T775L model can be used to stage multiple relays from two independent heat or cool setpoints. The number of stages for each setpoint can be freely chosen, limited by

the number of relays available (up to 12 using two T775S expansion modules). For example, programming could be (3 heat - 4 cool),

(5 heat - 1 cool), etc. In addition to the two staged loops, an additional two relays can be available for independent on-off control.
