The advanced ZXM2 Expansion Module allows you to easily add additional zones to the UZC4 Zone Control System. You can gain up to 18 additional zones for a total of 22. The robust and superior design, intuitive firmware, simple setup options, and easy to understand wiring, makes the UZC4 Zoning system the Contractors dream. Combined with EWC motorized dampers and practically any off-the-shelf heat/cool, heatpump or Multistage thermostat, EWC Controls once again proves to be the innovative leader in the residential & light commercial Forced Air Zoning industry.

Model ZXM2 Expansion ModuleThe ZXM2 Expansion Module can add up to 16 zones with 1 to 8 expansion modules on a UZC4 control system.

Compatible with most Off the shelf 1 or 2 stage Conventional H e a t / C o o l o r H e a t P u m p Thermostats. All Mechanical, Digital/Electronic, Dual Mode, and Internet Compatible Thermostats that operate on 24vac. Battery powered or Power robbing thermostats that draw less than 20 ma of current are also accepted.

The ZXM2 Expansion features automatic changeover from any thermostat allowing for individual zone comfort from the HVAC system.

The STATUS LED pulses as a steady heart beat to indicate active Micro- processor status.

LEDs indicate which dampers are o p e n .

TO PASS THE BUS CABLE THROUGH THE KNOCK OUTS OF THE HOUSING, FOLD THE 10-PIN HEADER

AGAINST THE CABLE SO IT WILL FIT EASILY.

FIELD BUS CABLES ARE ROUGHLY 40” IN LENGTH, SECURE CABLE AS NECESSARY.

KNOCK-OUT ON HOUSING

All Expansion module Dip switch banks must be set correctly for proper zone address identification. The 1st expansion module would be zones 5 & 6. The 2nd expansion module would be zones 7 & 8. The 3rd expansion module would be zones 9 & 10. And so on up the line for a total of 22 zones.

The switches are set for you at the factory unless you are expanding the system in the field. It is a good idea to check them anyway.

DO NOT CONNECT OR DISCONNECT BUS CABLES WHILE POWER IS APPLIED TO THE SYSTEM. DOING SO MAY DAMAGE THE ZXM2 MODULES AND VOIDS ALL WARRANTIES.

NOTE:THE ZXM-2 PACKAGE CONTAINS AN EXPANSION HEADER AND A 3-CONNECTOR CABLE (ITEMS NOT SHOWN). THESE ITEMS ARE ONLY REQUIRED IF YOU ARE EXPANDING A UZC6 TO A UZC8, CONTACT TECH. SUPPORT FOR DETAILS.

DAMPER WIRING, DAMPER TESTING AND POWER SUPPLY SOLUTIONS

TESTING DAMPER MOTORS

SR /SRE Power Open / Spring Close Dampers - Connect 24vac common & hot to the two motor (M) terminals. Damper should Open. Remove 24vac hot. Damper should Close.

ND / URD / SMD / BMD Dampers - Connect 24vac common to terminal 1 and 24vac hot to terminal 4. Damper should Open. Remove 24vac hot from terminal 4 and apply to terminal 6. Damper should Close

SR /SRE Power Close / Spring Open Dampers - Connect 24vac common & hot to the two motor (M) terminals. Damper should Close. Remove 24 vac hot. Damper should Open.

The Expansion module motor blocks must be powered by a separate transformer. This advanced design provides automatic 2.5amp over-current protection for each Expansion module motor block and allows a maximum 60va transformer to be connected. This means that you can directly connect a theoretical maximum of 12 Genuine ND/URD dampers to a single 2 zone expansion module. Now you no longer have to isolate & power up multiple dampers using field installed relays. The Expansion modules provide the isolation for you. See the diagram below for typical wiring solutions for dampers.
