Cooling with Heating Changeover
Using a duct sensor with the CTE-5202, an automatic
changeover is provided for cooling/heating applica-
tions. The duct sensor will switch the thermostat
between cooling and heating modes based on the
temperature of the duct supply air. A duct tempera-
ture higher than changeover temperature switches
control to heating mode, and a temperature lower
than changeover temperature switches control to
cooling mode.
Select Sequence 1 (from the CTE-5202 SYSTEM
menu). See Change Conguration on page 6 and
Hot/Cold Changeover on page 5. The default
changeover temperature is 77° F, congurable from
55 to 85° F in the CTE-5202 ADVANCE menu.
NOTE: Minimums can be set at zero air ow, but a
minimum of greater than zero is required
for a quick changeover.
