Mitsubishi Electric CN24RELAY-KIT-CM3 Relay Kit
The Mitsubishi Electric CN24RELAY-KIT-CM3 Relay Kit is a critical OEM component for technicians integrating supplemental heat control into M-Series and P-Series mini-split systems. This kit enables the indoor unit (IDU) to command external heating sources, such as electric baseboards or duct heaters, when the heat pump capacity requires assistance during extreme ambient drops. By utilizing the CN24 terminal on the indoor control board, the CN24RELAY-KIT-CM3 provides a dry contact signal to drive external relays, ensuring seamless HVAC system integration and maintaining setpoint stability in cold climate applications.
This Mitsubishi relay kit is specifically engineered for high-performance units including the SEZ-KD, SLZ-KA, PCA-A, PLA-A, and PEAD-A series. When configured with a PUZ or MXZ outdoor condenser, it allows for sophisticated staging of auxiliary heat. For contractors, this is the standard solution for external heat source control, replacing the need for complex "home-run" wiring field hacks with a plug-and-play 12VDC interface that maintains the integrity of the manufacturer’s logic.
Key Benefits for Installation:- Direct Interface: Connects directly to the CN24 port on the indoor unit PCB, eliminating guesswork during low-voltage wiring.
- Optimized Heating: Enables precise supplemental heat activation based on the system’s thermistor feedback and logic.
- Broad Compatibility: Supports a wide range of ducted and ductless M-Series and P-Series indoor units.
- OEM Reliability: Genuine Mitsubishi accessory ensures signal voltage accuracy and long-term HVAC controller communication.
- System Versatility: Allows for secondary heat sources to operate as emergency heat or stage-two supplemental heat.
How do I activate the supplemental heat function after installing this kit?
Activation typically requires adjusting the function settings via the remote controller or PAR-41MAA-J wall controller. You must set the specific code (such as Mode 23) to enable internal/external heater control logic.
Does this kit include the power relay for the heater?
No, the CN24RELAY-KIT-CM3 provides the command signal. A field-supplied external relay or contactor is required to switch the high-voltage load for the auxiliary heater itself.
Can this be used for fan control on third-party equipment?
This kit is primarily designed for external heater integration. Using it for other purposes may interfere with the indoor unit's logic cycle and is not recommended.
