STARTUP AND CHECKOUT After the installation is complete, verify the operation: 1.Put the Em Heat switch in the off (down) position. 2.Be sure the DIP switches are set correctly. See Sequence of Operation and Table 6 for correct configu- ration. The default position is in the off (down) position. 3.Power up the MABS EZ and set the thermostats so no zones are calling. Verify that the board? enters the Purge mode. NOTE: During the two- or three and one-half- minute Purge, the Purge LED should be amber. During this mode, the dampers are open and the damper LEDs are lighted green.4.Set the zone one thermostat to heat and raise the set- point to call for heat. The Heat LED is red and the zone one damper remains green while the other damper LEDs turn off. 5.Lower the setpoint in zone one and raise the setpoint in zone two to call for heat. Verify that zone one LED turns off (also zones three and four turn off when used on MABS EZ-4) and zone two damper is green. 6.When using a MABS EZ-4, repeat for zones three and four and verify correct operation. 7.Alternately, the setpoint can be lowered to call for cool- ing. Then the green cool LED lights.

MASTERTROL® AUTOMATIC BALANCING SYSTEM™ (MABS®) EZ ZONE (EZ-2 AND EZ-4) CONTROL PANELS 9 69-1360–2 OPERATION Sequence of Operation On a call for heating or cooling, the zone damper to the calling zone stays open, and the dampers close to the zones that are not calling. The MABS EZ panel brings on the heating or cooling and conditioned air is delivered to the calling zone until the zone is satisfied. When the call is satisfied, the system enters the Purge mode. This holds open the damper of the last zone calling and purges into that zone. The Purge time can be set to three and one-half or two minutes. Individual Zone Fan Control When all zones are satisfied, each zone thermostat Fan switch controls the fan operation for each zone. When circulation is desired, place the Fan switch in the On position. The fan runs and closes the dampers to the zones where the Fan switch is set to Auto. Multi-Stage Operation MABS-EZ can control up to two stages of heating and cooling using singe-stage thermostats. The panel uses a timer to control the second stage and is adjustable from five minutes to 30 minutes using DIP switches 5, 6, and 7. See Table 4. When a call for heating or cooling is not satisfied within the time set on the stage time, the panel energizes the second stage of heat or cool and both stages remain on until the call is satisfied. Changeover Operation The MABS EZ panel uses a standard heating and cooling thermostat for each zone to allow any zone to call for heating or cooling. When opposite calls are made from different zones, MABS EZ accepts the first call. Once the first call is satisfied, or a maximum of 20 minutes elapses from the start of an opposite call, MABS EZ allows the opposite call. Automatic changeover thermostats can also be used to provide automatic zone changeover. When opposite calls occur, the panel ensures that both calls are acknowledged. If the first call is not satisfied within 20 minutes, the panel drops the existing call and goes into the Purge mode. After completion of the Purge, the panel switches to the opposite mode until it is satisfied or until 20 minutes elapses.Then it goes back into the Purge mode and back to the original call. The system continues to switch back and forth until both calls are satisfied. Purge Mode At the end of every call for heat or cool, the panel enters a Purge mode that holds the last zone damper open for three and one-half or two minutes. During this time, the panel or HVAC equipment can operate the fan. Purge is a time delay that prevents short cycling of the heating and cooling equipment after each call. The Purge LED lights when the system is in Purge mode. Press Purge Override button when the purge LED is lighted to override Purge. Table 4. Stage timer configuration.

MASTERTROL® AUTOMATIC BALANCING SYSTEM™ (MABS®) EZ ZONE (EZ-2 AND EZ-4) CONTROL PANELS 69-1360–2 10 LED Indicators The panel features several LED status indicators visible through a window in the cover. See Table 6. Re-Booting the Microprocessor When conditions hang up the microprocessor, press and release the Boot button to re-boot the system and enter the Purge mode. ZoneMAX Sensor Leaving Air Temperature Sensor The ZMS (not included) is a duct-mounted temperature probe that monitors the supply of air temperature to control capacity and prevent over-heating or coil icing. The sensor attaches to the TL terminals at the upper left corner of the panel. See Fig. 9. IMPORTANT The ZMS wires must be at least 12 in. away from line voltage wiring to ensure correct operation. When not possible, shielded cable must be used. ZoneMAX Sensor Configuration DIP switches 2 and 3 set the ZoneMAX Sensor temperature limit. See Table 7. The recommended setting for fossil fuel/ heat pump systems is 160°F (71°C). For heat pump systems, the recommended setting is 120°F (49°). The cooling temperature limit can be set to 40°F (4°C) or 48°F (9°C). OPERATION If the system trips due to exceeding a high or low temperature, the heating or cooling system shuts down and the fan continues running to dissipate the conditioned air from the plenum. If the low limit was tripped, the cool LED flashes continuously until it resets. If the high limit was tripped, the Heat LED flashes continuously until it resets. The ZoneMAX Sensor resets and allows normal system operation when the supply air temperature rises ten degrees in cooling mode, or falls ten degrees in heating mode. The ten degrees provide adequate time to prevent short cycling of the unit. Circuit Breaker Protection A built-in thermal circuit breaker protects the panel against shorts in the thermostat and damper wiring and the remote occupied/unoccupied switch. It does not protect against shorts in the HVAC equipment wiring into the panel. OPERATION None of the LEDs light when the circuit breaker tripped. The fuse is a yellow square or rectangular disk located right of the TR1 and TR2 terminals. If it is hot to touch, remove panel power for ten seconds to allow the circuit breaker to cool off and reset. Table 5. Purge DIP switch settings.
