Fig. 60. Program - Setback.
2.1.3. SETBACK
The Setback temperature option displays only if
scheduling is enabled (see Fig. 47 on page 21) or the DI
Option is set to Setback. (see Fig. 49 on page 22).
This is the desired setpoint temperature that you want to
use during setback mode for this output. For example, if
your setpoint is 70°F and you want the temperature to
drop 10°F during setback mode, enter 60°F as the set-
point for this output.
1. From the menu, use the S and T buttons to high-
light SETBACK.
2. Use the S and T buttons to increase/decrease the
desired setpoint temperature.
Default: 60°F (16°C)
Range: -40°F to 248°F (-40°C to 120°C)
3. Press the X button to accept the value and display
the menu.
Fig. 61. Program - Sensor.
2.1.3. SENSOR
This sub-menu choice is only available on the T775U2016
model.
1. From the menu, use the S and T buttons to high-
light SENSOR A or SENSOR B.
2. Press the X button to accept the sensor selection
and display the next option.
Fig. 62. Program - Throttling Range or Differential.
2.1.5. THROTTLING RANGE or
DIFFERENTIAL
Throttling Range displays for Modulating outputs.
Differential is used for the Relay outputs.
1. From the menu, use the S and T buttons to high-
light THROT RNG or DIFFERNTL.
2. Press the X button to display the throttling range
value.
3. Use the S and T buttons to increase/decrease the
desired value.
Default: 20°F (-6.6°C)
Range: 1°F to 150°F (1°C to 66°C)
4. Press the X button to accept the value and display
the next option.
The Throttling Range brackets the setpoint setting, e.g., if
the setpoint is 72°F and the throttling range is 10°F, then
the effective throttling temperature range is 67°F to 77°F.
In heating mode, the Differential is below the setpoint.
The relay de-energizes when the temperature rises to the
setpoint. As the temperature drops to the setpoint minus
the Differential, the relay energizes.
In cooling mode, the Differential is above the setpoint.
The relay de-energizes when the temperature falls to the
setpoint. As the temperature rises to the setpoint plus the
Differential, the relay energizes.
