The Setback temperature option displays only if
SETBACK
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
60 o
F
your setpoint is 70°F and you want the temperature to
drop 10°F during setback mode, enter 60°F as the set-
ENTER
point for this output.

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.
