iZone C325M2 Mitsubishi Electric Air-Conditioner Interface Module
The iZone C325M2 is a communication interface designed to connect an iZone C225 control system with compatible Mitsubishi Electric ducted and City Multi VRF air conditioners. It enables integrated air-conditioning and zoning control through the iZone touchscreen, temperature sensors and mobile app when a Smart Hub is installed.

Controls system on/off, operating mode, set temperature and fan speed
Supports selected R410A and R32 ducted systems
Supports selected Mitsubishi Electric City Multi VRF indoor units
Supports return-air and iZone zone-temperature control when correctly configured
Communication wiring is non-polarised
App control available when connected to an iZone Smart Hub
Ducted-System Compatibility
| System type | Compatible indoor models |
|---|
| R410A ducted, 10–14 kW | PEA-M##GAA series |
| R410A ducted, 10–14 kW | PEA-M##HAA series |
| R410A ducted, 10–14 kW | PEA-M##JAA series |
| R32 ducted, 16 kW | PEA-M160HAA |
| R32 ducted, 18 kW | PEA-M180LAA.TH |
| R32 ducted, 20 kW | PEA-M200LAA.TH |
| R32 ducted, 25 kW | PEA-M250LAA.TH |
Older R410A PEA-RP200WJA and PEA-RP250WHA systems require the earlier C325M module.
City Multi VRF Compatibility
Compatible with selected indoor units from the following series:
PEFY-P VMR-E-L/R low-noise ceiling units
PEFY-P VMS1(L)-E low-static units
PEFY-P-VMA(L)-E4 medium-static units
PEFY-P VMX(L)-E compact-depth units
PEFY-P-VMHS-E high-static units
PEFY-P VMHS-E-F fresh-air units
PKFY-P-VLM-E and PKFY-P-VKM-E wall-mounted units
Selected PUMY-P and PUMY-SP outdoor systems
VRF operation requires compatible firmware across the complete iZone system.
Connection Requirements
Connects to the indoor unit’s remote-controller circuit
Compatible terminal designations: A/B or 1/2
Polarity is not critical
Connect the remote-controller wiring to the AC Unit Control Cable connection on the C225/C325M2
Use shielded two-core twisted-pair control cable
Important Installation Information
For compatible R32 systems, DIP switch 8 on SW5 must be set to the OFF position. Perform a complete power reset after changing the switch setting.
For VRF installations, the indoor unit’s configured sensor location must match the iZone temperature-control selection. Incorrect configuration may cause the system to cycle unexpectedly.
Always confirm the complete indoor and outdoor model numbers before ordering.
