Temperature Sensors
a
(Sensor A or B)
The controller accepts 1,097 Ohms PTC at 77°F (25°C):
• 50021579-001 – Standard sensor (included with all
models except NEMA 4X models)
• T775-SENS-WR – Water resistant with 5 foot leads
(included with NEMA 4X models)
• T775-SENS-WT – Watertight with 6 foot lead
• T775-SENS-OAT – Outdoor air temperature sensor
• C7031D2003 – 5 inch immersion sensor with wiring
box (use immersion well; P/N 50001774-001)
• C7031J2009 – 12 foot duct averaging sensor with
wiring box
• C7046D1008 – 8 inch duct probe with mounting flange
• C7100D1001 – 12 inch fast response, duct averaging
sensor with flange
• C7130B1009 – Room mount sensor
Differential Pressure Sensors
(Sensor A only)
P7640A and PWT pressure transducer models with
selectable pressure ranges can be used.
The controller accepts pressure sensors with a signal
output of 0-10 Vdc or 4-20 mA for any output range within
the following ranges (the minimum and maximum for the
sensor output range can be adjusted within the following
limits):
• -500 to 500 PSI
• -30.0 to 30.0 inches w.c.
• -3,000 to 3,000 Pa
• -3,000 to 3,000 kPa
Humidity Sensors
(Sensor A only)
The controller accepts 0-10 Vdc or 4-20 mA input with a
range of 0-100%.
H7625, H7635, and H7655 models (available in 2, 3, and
5% RH accuracy) can be used.
CO
2
Sensors
The controller accepts a 0-10 Vdc or 4-20 mA input from
C7232 and C7632 CO
2
sensors and is settable in PPM
units.
Universal Sensors
(Sensor A only)
The controller accepts 0-5 Vdc, 0-10 Vdc or 4-20 mA input
for temperature, pressure, humidity CO
2
, etc. They may
be programmed in units of °F, °C, %, Pa, kPa, PSI, In
W.C., PPM, or may be unitless (none).
The PPM range is 0 to 9990.
Choosing none for units, results in no units being
displayed on the home screen. If no unit is specified the
range is -9999 to +9999.

Product Changes
Below are the changes to T775U models starting with
Series 3 (March 2009). Series 3 can be identified by the
sideways 3 after the part number on the device label.
1.
Setpoint and Enable options added to the DI
options.
2.
0-5 Vdc sensor inputs are now available (for both
models).
3.
MIN ON time added.
4.
HIDE option added to MOD1 and MOD2 (to hide
them on the home screen).
5.
PPM and None added to sensors’ unit of measure.
6.
With the new T775U2016 model, all outputs can be
controlled to Sensor A or Sensor B. The
T775U2006 model controls only to Sensor A.
