Economizer and Time of Day (TOD)
Operation
Economizer
The thermostat controls an economizer module to provide
ventilation during occupied periods and free cooling when
outdoor conditions are favorable. In some climates the cooling
system may run several hours when it may not be required to
maintain indoor comfort. When outdoor conditions are
favorable, ventilation with outdoor air can achieve the same
level of comfort at lower cost. Table 5 explains how the
Economizer Module is controlled by the thermostat.
The thermostat works with the W7220, W7212, W7213 and
W7214 Economizer Modules for both heat pump and
conventional systems.
