Infinity Box 858-255 NGX Vintage Air Control Expansion Harness

This is the accessory expansion harness that lets you control the heat & A/C functions on a Vintage Gen 4 or Gen 5 system.  It easily connects into the B connector on the MASTERCELL NGX that came with your Intelligent Power Management IPM1 Kit.  This will let you control the temperature, fan speed and the blend of your heat & A/C through the inTOUCH feature on inLINK NGX or through our inCONTROL rotary interface.  You must have either inLINK NGX or inCONTROL to use this feature.

Please note that this only works with our Next Generation NGX system.  It will not work with our Legacy 3-Cell Kit or the 20-Circuit Kit.

• Optional inVIRONMENT expansion harness for the MASTERCELL NGX B connector
• Add-on to the standard IPM1 Kit to let you interface with your Vintage Air Gen 4 or Gen 5 heat & A/C so you can control it through inCONTROL or the inTOUCH feature on inLINK
