outside temperature), and is used only to reset the
controlled setpoint. In Non-reset applications, Sensor B
can be used to monitor some third temperature.
Programming the T775P
Controller
To program the controller, perform the setup configuration
(see “1. Setup”) and then select one of the following
procedures depending on whether the Reset function is to
be used:
• Program the Outputs for Reset —
see “2. Programming Output Stage(s) with Reset”.
• Program the Outputs for No Reset —
see “3. Programming Output Stage(s) with No Reset”
on page 29.
When programming is complete, you may continue with
“4. Scheduling” on page 31.
1. SETUP
Setup provides the ability to change the factory default
settings for the temperature sensors and outputs, to
enable/disable reset control, and to enable/disable
scheduling.
IMPORTANT
If the stage configuration is changed (e.g., the
number of stages [relays] changes) then you
must re-select the pump stage in Setup.
NOTE: The T775P controller interface is intuitive.
You may want to use this procedure simply
as a reference to locate the particular option
or parameter of interest.

keypad activity for four minutes, you exit
Setup mode and return to the home screen.

that is easy to use. You press the and arrow buttons
to move forward and backward through the menus.
NOTE: The menus can display only those relays that
are defined in Setup (see “1.3.1. Number of
STAGES” on page 15). For example, if you
configure only two relays, then only two
relays (stages) display on the appropriate
menus.
