2.2.4.2. THROTTLING RANGE

only)
The throttling range for the modulating high or low limit
positions the setpoint at the end of the throttling range.
For example, with a high limit at Sensor B of 200°F and a
throttling range of 10°F, the modulating output controlling
Sensor A begins to throttle back at 190°F
(88°C), and fully closes at 200°F (93°C). Conversely, the
throttling range for the low limit begins above the setpoint
in the same manner.

NOTE: The menus (e.g. the Outputs menu shown
here) can display only those relays that are
defined in Setup (see "2.3.2. NBR OF
RELAYS" on page 24). For example, if you
configure only two relays, then only two
relays display on the appropriate menus.

The following procedures set up each modulating output
and relay output.

2.3.1. Setting up the Modulating Outputs

1. From the Output menu, use the
tons to highlight the desired modulating output
(MOD 1 or MOD 2).
2. Press the
menu.
NOTE: Modulating outputs are not available on the
T775A and T775B controller models. If you
are setting up one of these controllers, skip
to "2.3.2. NBR OF RELAYS" on page 24.

Use the remaining procedures, beginning with "2.3.1.1.
TYPE (of output signal)" on page 22, to set up each
modulating output. If you have two modulating outputs,
repeat these procedures for each modulating output.
