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

Cooling with Heating Changeover

Using a duct sensor with the CTE-5202, an automatic
changeover is provided for heating/cooling 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.

menu). See Change Configuration on page 6

NOTE: The CTE-5202 uses the 16 VDC power
from the CSP-5001. If replacing a CTE-5103
thermostat as described in the Cooling and
Heating Changeover section of the
5001/5002 Applications
1005 relay module is no longer needed with
the CTE-5202.
NOTE: If using an existing TTE-2001 duct sensor/
transmitter (instead of an STE-140x duct
sensor), connect to Terminals 1 and 2.

NOTE: Minimums can be set at zero air flow, but a
minimum of greater than zero is required
for a quick changeover.
