Pressure Independent VAV Applications with CEP/CSP-4000 Series 49 CTE-5202 Applications Guide, AN0912A Rev. H

Cooling with 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 may still

be available. 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.
