KMC Controls CTE-5202 Application Guide

Pressure Independent VAV Applications with CEP/CSP-4000 Series 47 CTE-5202 Applications Guide, AN0912A Rev. D
Cooling with 3-Stage Reheat
The application below uses an SSE-1000 series sen-
sor, an REE-4001/5001 relay module, and three 24
VAC contactors for three stages of reheat.
The transformer must supply a minimum of 10 VA
plus the requirements for the reheat contactor coils
(10 VA maximum per stage).
As the temperature drops below setpoint, the rst
stage of reheat begins. If the temperature continues
to drop, the second stage begins, and nally the
third stage if necessary.
Select Sequence 2 (from the
CTE-5202 SYSTEM menu).
See Change Conguration
on page 6. (This replaces a
CTE-1004 or a CTE-5002/5012
thermostat.)
If no Auxiliary Flow is desired,
set AO1 AUX to 0 in the
LIMITS menu.)
