Description
The Field Controls RJR-5 Ice-Cube Relay Kit CK-40 CK-41 CK-90 CAC-24 switches electrical circuits in compatible heating and ventilation equipment using a 24V control signal. Its contacts open or close connected electrical circuits when the coil receives the required control voltage, allowing one circuit to operate another through the relay. The kit installs within standard HVAC systems with the relay, socket, and wiring connected according to the equipment circuit. The relay activity supports coordinated switching of connected motors and controls during normal equipment sequences.
