Install Instructions

1. SETUP T775P SERIES 2000 CONTROLLER
15 62-0256–03
Fig. 27. Setup - Sensors - Sensor C Menu.
1.2.4. SENSOR C
Normally, Sensor C is used to sense the Return
temperature and is used to activate the Differential alarm
(the difference between Sensors A and C) and/or can be
the controlled temperature sensor.
If you are implementing two-sensor reset control, Sensor
A (supply) or Sensor C (return) must always be the
controlled temperature.
1. From the Sensors menu, use the T button to high-
light SENSOR C.
2. Press the X button to display the Sensor C menu.
3. Repeat the selections described in
“1.2.2.2. CALIBRATE (the sensor)” through
“1.2.2.4. Exit Sensor A Setup” beginning on
page 14.
Continue with “1.3. Setting up the Outputs”.
Fig. 28. Setup - Outputs Menu.
1.3. Setting up the Outputs
1. From the Setup menu, use the Sand T buttons to
highlight OUTPUTS.
2. Press the X button to display the Outputs menu
Continue with “1.3.1. Number of STAGES”.
Fig. 29. Setup - Outputs - Number of Stages.
1.3.1. Number of STAGES
1. From the Outputs menu, use the Sand T buttons
to highlight # STAGES.
2. Press the X button to display the number of stages.
3. Use the S and T buttons to select the number of
stages depending on setup. (See notes below.)
Default: 4
4. Press the X button to accept the value and display
the Outputs menu.
NOTE: Up to two T775S Expansion Modules can be
connected to a T775P, making the following
outputs (stages) available:
T775P: 4 relay outputs (4 stages).
T775P with one T775S module: 8 relay outputs
(8 stages).
T775P with two T775S modules: 12 relay
outputs (12 stages).
NOTE: The last output is available to be used as the
pump output. For example, a T775P with one
expansion module provides 8 outputs, and the
last output (#8) is available for use as the pump
output. See “1.3.5. Setup Last Output” on
page 21.
If # of stages = 1, 2, or 3 then, pump = 4.
If # of stages = 4, 5, 6, or 7 then, pump = 8.
If # of stages = 8, 9, 10, or 11 then, pump = 12.
