INSTALLATION

The Mini-MasterZone™ Zoning System-3 is a two (2) and three (3)

zone control panel for single stage heating only, cooling only or

heating and cooling. The MMZ3 can control any single stage gas-oil-

electric furnace, hydro-air heating and air conditioning. The MMZ3

panel is the central control panel where all zone dampers, zone

thermostats, HVAC Equipment and power transformer are wired.

When installing the MMZ3 panel it is important to pick a central

location where it is most convenient to bring all the wires. Most often

this is at the furnace or air handler. It is often the most convenient

location and closest to power, the HVAC unit controls and the zone

dampers when typically located at or near the plenum.

The MMZ3 panel is made of sturdy ABS plastic and can be mounted to

any flat surface. It is recommended that the panel be mounted to a

wall or return plenum and NOT on the furnace or plenum where it will

be in contact with the high temperatures. The panel can be located in

an attic space or in an enclosed cabinet of a rooftop unit, provided the

panel enclosed and not in direct exposure to the elements.

The cover easily removes from the case by pulling firmly and separating

the cover from the case exposing the circuit board. There are 4 key-

hole mounting points in each corner of the case. The case has

openings in the rear of the case as well as the side for all wiring.

Wiring can come from the back as well as the side in order to make a

neat installation.

OPERATION

The MMZ3 can controls single stage heating and cooling HVAC

Equipment. The MMZ3 is compatible with any standard single stage

thermostat and setback thermostats as well. The MMZ3 has various

features that make installation and checkout very simple for all of the

board’s functionality.

The MMZ3’s basic function is zone control. On a call for heating or

cooling, the panel will accept the first call from any zone. Upon

accepting this call the MMZ3 will keep open the damper(s) to the zone
