shows RELAY 1.
NOTE: For MOD 1 and 2, THROT RNG replaces
DIFFRNTL.
NOTE: The Setback parameter displays only if
scheduling is enabled (See Fig. 57 on
page 24) or the DI Option is set to Setback.
(See Fig. 60 on page 26).

Fig. 30. Program - Setpoint.
1.2.1. SETPOINT
1. From the menu, use the and buttons to
highlight SETPOINT.
2. Press the
button to display the setpoint value.
3. Use the
and buttons to increase/decrease
the desired setpoint temperature.
Default: 70° F (21° C)
Range: -40° to 248° F (-40° to 120° C)
4. Press the
button to accept the setpoint
temperature and display the next option.
Fig. 31. Program - Differential or Throttling Range.
1.2.2. DIFFERENTIAL or THROTTLING
RANGE
Differential is used for Relay outputs and Throttling Range
is used for Modulating outputs.
1. From the menu, use the
and buttons to
highlight THROT RNG or DIFFERNTL.
2. Press the
button to display the throttling range
value.
3. Use the
and buttons to increase/decrease
the desired value.
Default: 20° F (-7° C)
Range:to 300° F (1° to 14C).
4. Press the
button to accept the value and display
the next option.
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.
The Throttling Range brackets the setpoint setting, e.g., if
the setpoint is 72°F (22° C) and the throttling range is
10° F (-12° C), then the effective throttling temperature
range is 67° to 77° F (1 to 25° C). This applies to both
modulating outputs and floating outputs.
