2.2.4.2. THROTTLING RANGE (Sensor B 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 (Heat) 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, and fully closes at 200°F. Conversely, the throttling range for the low limit begins above the Cooling setpoint in the same manner.

1.

From the Limit menu, use the T button to highlight

2.3.1. Setting up the Modulating Outputs

1.From the Output menu, use the S and T buttons to highlight the desired modulating output (MOD 1 or MOD 2).

2.Press the X button to display the selected MOD 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.
