Cooling/Heating Changeover - KMC Controls CTE-5202 Application Manual

Cooling/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.

described in the CTE-5001/5011 Installation
Guide, the REE-1005 or REE-1014 relay
module is not needed with the CTE-5202.
NOTE: Minimums can be set at zero air flow, but a
minimum of greater than zero is required
for a quick changeover.
