Ratings:
Operating Ambient: 30°F to 110°F (-1°C to 43°C).
Shipping: -30°F to +150°F (-34°C to +66°C).
Display Accuracy: ±1°F (±1°C).
Setpoint:
Range:
Heating: 40°F to 90°F (4°C to 32°C).
Cooling: 45°F to 99°F (7°C to 37°C).
Deadband: 2°F (1°C).
Default Settings: See Table 5.
Loss of Power: The thermostat maintains programmed times
and temperatures for the life of the product. Clock and day
information is retained for a minimum of 48 hours.
NOTE: To achieve the 48-hour power-loss clock retention,
the T7350 must be powered for at least 5 minutes.
