Honeywell Air Conditioner MM 3 User Manual

MM-3 MASTERTROL®  
MINI-ZONE™-3  
SCHEMATIC  
The Mastertrol® Mini-Zone™ -3 Zone Control Panel,  
Model MM-3, controls up to 3 zones on any single  
stage heating and cooling system.Each zone is con-  
trolled by a thermostat which operates a motorized  
damper in the it’s zone duct to control the flow of  
conditioned air to the zone. (Up to 2 dampers may  
be wired to a single zone. When 3 or more dampers  
are required a Slave Damper Control Relay, Model  
SDCR, is required.)  
HYDRO-AIR Systems - When using the MM-3 with  
ZONE THERMOSTAT WIRING - The MM-3 can be  
used with several different single stage thermostats.  
The wiring shown is for the following recommended  
thermostats:  
a Hydro-Air System, one which uses a hot water coil  
in the air handler to provide heating in place of a  
furnace, the wiring is almost similar to that shown. In  
this application the Heat Relay shown may be a zone  
valve or circulator relay. The Fan must often be  
brought on with the call for Heat. To provide for this,  
jumper the Gh and G terminals on the MM-3.

OIL FURNACES - When using the MM-3 with an Oil  
Fired Furnace to provide heating the T and T termi-  
nals on the Oil Burner Primary Control must wire to  
the B andW wires.NOTE:Once operational if the Oil  
Furnace continues to run when all zones are satis-  
fied, reverse the B and W wires on the MM-3.

The Zone 1 Thermostat requires a manual  
changeover subbase with “O” and “B” terminals.The  
“O” terminal must make with R when the subbase is  
switched to the COOL Mode. The “B” terminal must  
make with R when the subbase is switched to the  
HEAT Mode.When the Zone 1 Subbase in either the  
Heat or Cool Mode, any one of the 3 zone thermo-  
stats can call for the respective mode.The zone ther-  
mostat will energize it’s zone relay which activates  
the heating or cooling controls, opens it’s zone  
damper and close the dampers to the zones that are  
satisfied.When all zone thermostats are satisfied the  
heating or cooling will shut off and all zone dampers  
will return to their normal position.The normal posi-  
tion of the zone dampers is set by the OPEN/  
CLOSED slide switch next to the motor terminals.  
*These thermostats may require additional wires.  
Refer to the wiring information included with the ther-  
mostat for complete information.  
DAMPER MOTOR WIRING - This diagram shows  
Trol-A-Temps typical power open-power closed op-  
posed blade damper motors. Note the jumper wire  
required on the motor terminals 2 and 5. Round  
Spring Return Dampers can also be wired to the  
MM-3. When using the ARD-PC (D835), wire to the  
M1 and M6 terminals. When using the ARD-PO  
(D837), wire to the M1 and M4 terminals.  
IMPORTANT:When using the MM-3 as only a 2 Zone  
Panel, the Zone 3 Relay must remain plugged into  
its socket.
