Accessing the Menus

Menus are used for programming, scheduling, viewing the
summary settings, and setup of advanced options.

Scheduling is enabled from the Setup menu's Output
settings (Refer to "3.3.5.1. USE SCHED" on page 26).
Setup Menu
To access the Setup menu for advanced options, press
and hold the MENU button for five seconds (See Fig. 23).

NOTES:
1. If you press the HOME button or there is no
keypad activity for four minutes, you exit
Program mode and return to the home
screen.
If you press the MENU button, you exit and

return to the menu.

PROGRAMMING

The controller must be programmed before being placed
into service.
IMPORTANT
During programming, the controller is live at all
times. For example, the contacts may open and
close when adjusting the setpoint.
The programming process uses a hierarchical menu
structure that is easy to use. You press the  and 
arrow buttons to move forward and backward through the
menus.
NOTES:
1. The T775P controller interface is intuitive. You
may want to use these procedures simply as
a reference to locate the particular option or
parameter of interest.
2. The menus can display only those relays that
M24300
are defined in Setup (Refer to "3.3.4. NBR OF
RELAYS" on page 25). For example, if you
configure only two relays, then only two relays
display on the appropriate menus.
If you press the HOME button or there is no

keypad activity for four minutes, you exit
Program mode and return to the home
screen.
4. If you press the MENU button, you exit
Program mode and return to the menu.

Setpoint and Differential

The following describes the relationship between setpoint
and differential for heating and cooling. These settings are
programmed for each output relay.

Heating Mode Setpoint and Differential

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.
Cooling Mode Setpoint and Differential
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.
Setpoint High Limit
You can set an irreversible setpoint high limit maximum
value for any single displayed setpoint value.
Adjust the setpoint (at any output) to the desired
maximum setpoint. Then, simultaneously press the
HOME, , and  buttons and continue to press all three
buttons for five seconds to set the setpoint high limit
maximum to this value.
NOTE: You must press all three buttons at exactly
the same time for this action to occur.
