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.
