KMC Controls CTE-5202 Application Guide

Pressure Independent VAV Applications with CEP/CSP-4000 Series 49 CTE-5202 Applications Guide, AN0912A Rev. D
Cooling with Proportional Hot Water Reheat
See Cooling with 3-Stage Reheat on page 47. This
application operates similarly except for using a hot
water valve instead of electric heating elements for
reheat.
AO1 controls airow and AO2 controls the valve.
When there is a call for heat, the thermostat
modulates the hot water valve.
The CTE-5202 here replaces
a CTE-1004 (DA cooling and
RA heating) and is used in
conjunction with an REE-
4006 time proportioning relay
module and a (NC) VEP-
12/22/34 series hot water valve.
The REE-4006 relay is designed for
time proportioning control of thermic
electrical hot water valves.
NOTE: The VEP-12/22/34 series valves
and REE-4006 relay module
have been discontinued.
Replacement actuators (MEP-
3001s) for those
valves are still
available (as of Oct.
2012). The REE-4006
can be replaced
by an REE-4106 or
REE-5106, which
have built-in power
supplies that could
be used to power
the CTE-5202
if desired.
