Cooling and 3-Stage Reheat
This application uses a CSP-5001 along with an
REE-5001 relay module and three 24 VAC contactors
for three stages of reheat.
As the temperature drops below setpoint, the rst
stage of reheat begins. As the temperature continues
to drop, the second stage and later the third stage
begin as needed.
Select Sequence 2 (from the CTE-5202 SYSTEM
menu), with or without Auxiliary Flow (AO1 AUX
in LIMITS menu). See Change Conguration on
page 6.
(See also the Cooling with 3-Stage Reheat section
with a CTE-5104 for auxiliary ow or a CTE-5103
without auxiliary ow in the CSP-5001/5002 Appli-
cations Guide.)
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).
NOTE: See also the REE-
5001 Installation
Guide.
