The ZoneFirst MMP3 is a single-stage zoning panel designed for 2- and 3-zone heating and cooling systems. Constructed from durable ABS plastic, it operates on 24V AC at 50/60 Hz and features screwless push-in terminal blocks for effortless wiring. The MMP3 is compatible with standard 4-wire (Y-G-R-W) thermostats and supports both heating-only and cooling-only applications.
This zoning panel simplifies installation with color-coded wiring blocks and built-in LED indicators for system status. It works exclusively with plug-in zone motors such as the ZDSP, ZDBP, RDP, and RRP dampers, providing a seamless zoning solution. The advanced surface-mount electronic technology ensures reliable performance in residential and commercial Zone First HVAC systems.
When installing the MMP3 panel, it is important to choose a central location where it is most convenient to route all necessary wiring. Typically, this is near the furnace or air handler, close to the power source, HVAC unit controls, and zone dampers, which are often positioned at or near the plenum.

Yes, I would recommend this product to a friend or co-worker
I bought this controller to replace the two zone one already installed at my house. I was expanding the heating to add a third zone and this was a really simple solution. It was plug and play and the wiring was the exact of what I had, only it allowed me to wire an additional thermostat to it. Very straightforward in my case.
