Note that if this system is to be used as a night heat package with the room temperature being set back to a lower
value then that used in the daytime, this system would require a separate night thermostat and a device switching
between the day and night thermostats. See Diagram D1 below.
2. "X" and "Z" Override (Day and night operation)
NOTE: The unit will not discharge at the Master set point setting. During day operation the discharge
temperature will be either:
Dial setting plus max upward reset, or
Dial setting minus max downward reset.
During night discharge as set on night set point pot (100° - 120°F)
The amount of reset is determined by pot 5. Refer to the table in the section on Modulating Room Reset. (Section XVII,
page 17). Note that the table shows a minimum temperature and a maximum temperature for the discharge set point and
pot 5 settings. (Reset amount is not linear). When using this reset system the discharge temperature will modulate to
maintain the minimum or maximum and will not operate at the discharge set point.
Dipswitch A-3 must be on to activate this feature.
