KMC Controls Constant Volume Control with Override Relay Module

Constant Volume Control with Override Relay Module The KMC REE-1004 Relay Module is designed for constant volume control of VAV terminal units in HVAC systems. Used in conjunction with specific CEE/CEP/CSE/CSP series of con­trol­ler-actuators, it is capable of controlling a terminal at a con­stant setting, but has the ability to drive it fully open or closed with a contact closure. Since the desired air flow setting is made at the relay module, no room thermostat is required. KMC Relay Modules are intended for use with the following controller/actuators: CEE-4000 Series CEP-4000 Series CSE-4000 Series CSP-4000 Series Note: Image may not be actual representation of item.
