Cooling With Heating Changeover And Electric Reheat - KMC Controls CTE-5202 Application Manual

Cooling with Heating Changeover and Electric Reheat

This configuration is the same as the previous page
except for the addition of an REE-5001 relay module
connected to AO2 (for three stages of reheat) and
selecting Sequence 2 from the CTE-5202 SYSTEM
menu. See Change Configuration on page

NOTE: Minimums can be set at zero air flow, but a
minimum of greater than zero is required
for a quick changeover.
NOTE: Triac outputs on the REE-5001 are for 24
VAC loads only. The phase side of the
transformer connects to the "common" side
of the load (contactors).
