SPECIFICATIONS
IMPORTANT
Specifications given in this publication do not include
normal manufacturing tolerances. Therefore, an
individual unit may not exactly match the listed
specifications. Also, this product is tested and
calibrated under closely controlled conditions
and some minor difference in performance can
be expected if those conditions are changed.
Models (see Table 1):
The T775A,B Electronic Temperature Controllers provide
staged on-off temperature control for ducts, tanks, chillers,
heating and refrigeration units, and other applications
where electronic accuracy and remote sensing are desired.
The T775C,D Electronic Remote Temperature Controllers
provide staged on-off temperature control of heating,
cooling and ventilating systems in agricultural confinement
buildings, storage areas, and heavy industrial applications.
Dimensions: See Fig. 1 and 2.
Mounting: Mounts on any suitable horizontal or vertical
surface (see Fig. 3 and 4 for mounting hole locations).
Temperature Accuracy: +/-1°F (at nominal voltage in 77°F
[25°C] ambient, nominal sensor value). Accuracy may vary
based on deviation from nominal values of input voltage,
operating ambient and sensor ambient.
Setpoint Adjustment Range: -40° to 220°F (-40° to 104°C).
Display Resolution: Sensed temperature and other
operating parameters are displayed via a liquid crystal
display (LCD) with a resolution of 1°F or 1°C.
Operating Ambient Temperature:
One and Two Stage units: -30° to 140°F.
Three and Four Stage units: -30° to 125°F.
Operating Humidity:
5% to 95% relative humidity (rh) noncondensing.
Sensor: Positive coefficient platinum type, 4.8 ohms/ °F,
1000 ft maximum distance between sensor and solid
state controller (requires calibration over 400 ft). To
maintain NEMA 4X rating, use environmental-proof
cable and sensor.
Electrical Ratings:
Voltage Input: 24/120/240 Vac, 50/60 Hz (+10%/-15%).
Power Consumption:
For one and two stage units:
8 VA maximum at 60 Hz.
10 VA maximum at 50 Hz.
For three and four stage units:
13 VA maximum at 60 Hz.
20 VA maximum at 50 Hz.
