Max Ramp VDC
This feature limits the maximum voltage applied to the modulator while
operating in the Ramping mode. It has a setting range of 5 to 24 VDC. This
setting cannot exceed the maximum voltage output setting. This feature is
comprehensive to all Set Points.
Total Bandwidth (Global Setting)
This feature determines the amount of temp. change required to drive the
modulator from the minimum fire setting to the maximum fire setting and
vice versa. This feature is used to eliminate pulsating or hunting due to an
oversensitive application. Increase the Bandwidth if a pulsating or hunting
condition exists for an extended period of time after a Set Point change.
The feature has a range of 5°F (2.8°C) to 15°F (8.3°C). Total Bandwidth is
comprehensive to all Set Points.
Offset Temp
This feature is used to maintain a desired temperature in an area not
being directly sensed by the MP2+ system. The average difference be-
tween the MP2+ sensed discharged temperature and the desired space
temperature must be known. This is the Offset. The Offset will set the
MP2+ sensed discharged air needed to produce the desired space tem-
perature. Decrease (-) the Offset to maintain and control space tempera-
ture lower than MP2+ discharged temperature. Increase (+) the Offset to
maintain and control space temperature higher than MP2+ discharged
temperature. The space temperature will be displayed as the Process
Set Point.
Example
1 Program Offset to -5°F.
2 Program Process Set Point (desired space temperature) to 75°F.
3 Therefore discharge air temperature = 80°F.
(Required MP2+ discharge air temperature to maintain desired space temperature.)
4 The MP2+ discharged air temp. is 80°F. The displayed Process Set Point is 75°F.
The feature has a range of -10°F (-5.6°C) to +10°F (5.6°C) and is avail-
able for each Process.
Ramping
This feature is used to step the input rate when changing from one Pro-
cess Set Point to another. It is available for each Process. The Ramping
Rate determines the amount of temperature change per hour in one-min-
ute steps. It has a range of 60 Deg/hr to 900 Deg/hr. The change can be
positive or negative.
