Description

KMC REE-4001 relay modules are designed

primarily for use with VAV terminal units in

HVAC systems. When used with CTE series room

thermostats, up to three stag es of reheat may be

controlled. They may also be controlled by a 0 to 10

VDC output from a DDC or analog controller.

Each triac output circuit is capable of handling

contactors of up to 10 VA @ 24 VAC. The three

circuits are calibrated to actuate at equally spaced

intervals across the thermostat’s proportional band.

By using the REE-4001, the heating requirements of

a particular VAV terminal may be actuated in three

separate steps aording more precise temperature

control.

For controlling direct expansion compressors in

roof top units and other equivalent equipment, see

also the REE-4019 three-stage, wide-deadband relay

module.

When used with CTE series room thermostats, up to three stages of reheat may be controlled. They may also be controlled by a 0 to 10 VDC output from a DDC or analog controller.

Details All dimensions are in inches (mm) NOTE: Triac stages 1 through 3 are for 24 VAC loads only. This “C” terminal does NOT denote Common/Neutral. “C” is the phase side of the 24 VAC (and the phase side is where the three contactors are connected in “common”). “9” is the neutral side. NOTE: NOTE: For information about using the REE-4001 with a CEP-4000 series controller-actuator and CTE-1004 thermostat, see the CEP-4000 Series Applications Guide.
