selections.
3. Use the and buttons to select Heat or Cool.

3.5.5. SETBACK OFFSET
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 value is the number of degrees plus (+) or minus (-)
that you want the temperature to be offset from this relay's
setpoint.
For example, If you want the temperature to be 10°F less
than the relay's setpoint during setback mode, enter
-10°F. In normal operations for heating, the offset will be
negative. For cooling, the offset will be a positive value.
1. From the menu, use the and buttons to high-
light SETBACK.
2. Use the and buttons to increase/decrease the
desired setpoint temperature.
Default: 0°F
Range: -150°F to 150°F (-101°C to 66°C)
3. Press the button to accept the value and display
the menu.
3.6. Program Next Relay
If you have a second relay output, select that relay from
the Program menu, and go to "3.5. Program Menus for
the Additional Relays with Reset" on page 29.
When you finish programming the relay outputs, continue
with "3.7. Exit Programming with Reset".
3.7. Exit Programming with Reset
Press the HOME button to leave programming mode and
return to the home screen. This completes the
programming procedure for the additional relays that use
Reset.
IMPORTANT
To properly account for Daylight Saving time, be
sure to set the Date before setting the Time.
See "4.2.2. SET DATE" on page 33.
NOTE: The T775L controller interface is intuitive. You
may want to use this procedure simply as a ref-
erence to locate the particular option or parame-
ter of interest.
NOTE: Each loop and additional relay output can be
independently scheduled or not. For loops, see
"1.3.4.6. SCHEDULE" on page 19. For relay out-
puts, see "1.3.5.1. SCHEDULE" on page 21.
