Fig. 57. Program - Setback.
2.2.5. SETBACK
The Setback temperature option displays only if
scheduling is enabled (see Fig. 31 on page 15) or the DI
Option is set to Setback. (see Fig. 33 on page 16).
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.
2.3. Program Next Output (Loop or Relay)
For the next output (loop or relay), select the desired loop
or relay from the Program menu (see Fig. 51 on page 22).
Go to “2.2.1. SETPOINT” on page 22 to continue
programming.
When you finish programming the outputs, continue with
“2.4. Exit Programming without Reset”.
2.4. Exit Programming without Reset
Press the HOME button to leave programming mode and
return to the home screen.
This completes the programming procedure for
controllers that do not use Reset.
3. PROGRAMMING OUTPUT (LOOPS
AND ADDITIONAL RELAYS) WITH
RESET
The T775L can be programmed for Reset or No Reset for
each output. From the factory, the T775L is programmed
for No Reset. This section describes the steps necessary
to program the controller for Reset.
To use the Reset feature, Loop 1 must be set to
Reset=YES in Setup mode (see “3.1. Setting Up the
Controller for Reset”). The reset curve established when
programming Loop 1 is then used for the second Loop
and the additional relays.
The reset curve established when programming the first
Loop is then used for all subsequent Loops and any
additional relays that are configured for Reset, and each
of those outputs will be offset from this curve.
For all outputs that will follow a reset curve, be sure to
configure for Reset=YES in the setup mode. Choose
Reset YES or NO for all other outputs you wish to reset,
then press the HOME button to record your selection.
