• 4-20 mA; drive a maximum of 600 Ohms
• Electronic Series 90; requires 340 Ohm resistor (included)
across terminals R and W
• Floating
Sensed Temperature Limits (displayed):
• Minimum -60° F (-51° C)
• Maximum 270° F (132° C)
High Setpoint Limit: An irreversible high limit setpoint can be
configured to meet local code requirements.
Sensed Temperature Accuracy:
• T775: 1° F/C @ ambient room temperature of 77° F (25° C)
• 50021579-001 and T775-SENS-WR: ±0.42° from -22° to
248° F (+/-.24° from -30° to 120° C)
Setpoint Range: -40° to 248° F (-40° to 120° C)
Time Clock: Two settable time periods per day are standard
on all models.
Volatile Memory: The date and time settings are retained for
24 hours after a power outage. After a power loss of more
than 24 hours, the date and time settings may need to be
reentered. All other settings are stored permanently.
Approvals: UL 60730-1 standard, CuL, CE, C-tick

Humidity Sensors (T775U 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.
Low Differential Pressure Sensors (T775U only)
P7640A 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
Universal Sensors (T775U only)
The controller accepts 0-10 Vdc or 4-20 mA input for
temperature, pressure, humidity, etc. C7232 and C7632 CO
2
sensors are also compatible but output is displayed in %
instead of ppms. (A conversion graph is included in the T775U
