The Mini MasterZone™ Zoning Panel is a 2 and 3 zone, single
stage heating and cooling control panel. This electronic panel
provides the simplest zoning functions and works with all
standard heating and cooling thermostats. This panel has two
models to control different damper motors. The MMZ3 controls
24VAC damper motors. The NEW MMP3, shown in photo,
controls the New Plug-in Zone Motors that use modular cords,
supplied with each damper and the DC motors. This panel is
used exclusively with the ZDSP, ZDBP, RDP and RRP dampers.
The MM panels are designed to use a minimum of wires to make
zoning simple and affordable. Each zone uses a standard 4 wire
(Y-G-R-W) thermostat. The panels also feature a separate C –
Common terminal for 24 Volt powered thermostats. All terminal
blocks are color coded for each wire and have push–in
connections making wiring even simpler and no need for a small
screwdriver, as with all other zoning panels. The state of the art
surface mount technology for all electronic components makes
for a highly reliable control panel.
The zoning operation is very simple and basic. Any zone can call
for heating or cooling. Once the first zone calls, the panel will
only accept other calls for the same mode, either heating or
cooling. Once all of these calls are satisfied, or a maximum of 20
minutes elapses, the panel with cut off the HVAC Unit, purge the
conditioned air in the duct system and then look for opposite
calls. If opposite calls exist the panel will switch over and supply
that mode for the zones calling. When all zones are satisfied for
both heating and cooling, the panel will then accept Fan calls
from each thermostat’s Fan switch. This will provide for zoned air
circulation. Zones where the thermostat’s fan switch is ON, will
have their dampers open and the fan circulating air
continuously. Zones where the Fan switch is in AUTO, will close
their damper until a call is needed for heating or cooling. If all
thermostat Fan switches are in AUTO, the fan will be off and all
dampers return to a normally open position awaiting a call.
The panel also has simple Light Emitting Diodes (LED) indicators
to easily monitor the system status. Two LEDs can be seen
through the panel’s front cover. These monitor the basic system
operation. The SYSTEM LED is a 3 color LED and can indicate
when there is a call for Heating, the LED will be RED; a call for
Cooling the LED will be GREEN; and neither a call for heating or
cooling however if the Fan is ON for any zone the LED will be
AMBER. The second LED will be GREEN at all times indicating
power is applied to the panel. Each zone has a small green
indicator light as well showing when it is calling and the zone
damper will be open.
The MM panels are compatible with any single stage heating
and cooling system and is affordable enough that it can also be
used to zone heating only or cooling only systems as well. It can
control any Gas-Oil or Electric Heating Furnace, with or without
Cooling and also zone Hydro-Air Systems using a hot water coil in
a cooling air handler.
