Mount the thermostats in each zone of the livin g space usin g the installation instructions provided with each thermostat. 2. Mount the dam pers in the ductwork using the installa- tion instructions provided with each damper. 3. Mount the TZ-3 zone panel near the HVAC equipment; locate it on a wall or on the cold-air return. See Fig. 2. 4. Level the TZ-3 for a ppearance only. Wiring CAUTION Voltage Hazard. Can cause electrical shock or equipment damage. Disconnect power before continuing installation. Wirin g must comply with applicable codes, ordinances, and regulations. 1. Connect thermostats as shown in Fi g. 3-5. 2. Connect dampers as shown in Fig. 6-10. 3. Connect the Discharge Air Temperature Sensor (not su pplied) to the TL terminals.The wires are not polar- ized. See Fig.12. 4. Connect Add-A-Zone panels (if used) to the AZ1 and AZ2 terminals. The AZ1 terminal on the TZ-3 must be wired to the AZ1 terminal on the TAZ panel. Similarly, the AZ2 terminal must be wired on the TZ-3 to the AZ2 on the TAZ. See Fi g. 13. 5. Connect the HVAC equipment to the EQUIP terminals on the panel. See Fig. 14-17. 6. Connect a 40 VA, 24 volt transformer to TR1 (hot) and TR2 (common). This must be a dedicated transformer and any additional TAZ boards also each require a transformer. See Fi g. 11.Fig. 2. TZ-3 mounting location. Wiring Diagrams (Fig. 3-17) Conventional Thermostats The C (common) terminal is used only on thermostats that require a common (for example:T8601). See Fig. 3. Wire the W2 terminal on a multi-sta ge thermostat (for example: T8624) to the W2 on the panel for second stage control from the thermostat. If the thermostat has a Y2 terminal, do not connect it to the panel. Fig. 3. Typical single-stage thermostat wiring. Heat Pump Thermostats Select a heat pump thermostat from Table 1. If the thermostat selected has a se parate Y1 and W1, see Fig. 4. When using the thermostat to control the second stage of heat (W2), set DIP switch 5 to On, and DIP switch 1 to Off.

NOTE: If the installation includes an Add-A-Zone panel, see the TotalZone Add-A-Zone Panels section. Fig. 11. Transformer wiring. Discharge Air Temperature Sensor Wire the C7735A or the ZMS to the panel as shown in Fig. 12.Fig. 12. Discharge Air Temperature Sensor (C7735A or ZMS) wiring. Add-A-Zone Panel Wire the Add-A-Zone (TA Z) Panel to the TotalZone (TZ-3) Panel as shown in Fi g. 13. Up to nine TAZ Panels can be wired to one TZ-3 panel. See Fig. 13. Use 18- gauge thermostat wire for runs up to a maximum of 500 feet. Keep these wires at least 12 in. from line voltage wiring and equipment; otherwise, use shielded cable wiring. IMPORTANT: When multiple panels are used, it is important that the transformers be in-phase. Check the phasing by measuring for 24V across the TR2 transformer termi- nals on each panel. There should be 0 Vac. If not, reverse the TR1and TR2 transformer wires on one of the panels and recheck. Fig. 13. TotalZone Add-A-Zone wiring.

Water source heat pump wiring. STARTUP AND CHECKOUT After the installation is complete, verify correct operation as follows: 1. Place the Em Heat switch in the Off (down) position. 2. Place the Zone-A-Lone switch in the Occup/Remote (up) position. 3. Ver i f y that the DIP switches are set correctly. See Sequence of Operation section and Table 6 for correct confi guration. 4. Power up the TZ-3 and set the thermostats so no zones are calling. The board then enters the Purge mode where all dam pers open and the fan operates for two or three and one-half minutes (configurable). (If there is no Discharge Air Temperature Sensor connected to the panel, the Idle LED flashes seven times before entering the Purge mode.) Then the Idle LED turns red and each damper LED turns green. 5. Set zone one thermostat to heat and raise the set point to call for heat. Verify that the heat LED is red and zone one damper remains green while the other damper LED turns red. 6. Raise zone two set point to call for heat. Lower zone one set point to stop the call for heat to that zone. Verify that zone one LED turns red (it may be amber while moving) and zone two LED turns green. 7. Re peat for zone three. 8. Alternately, lower the setpoint to call for cooling.Verify that the green cool LED illuminates.

TZ-3 TOTALZONE® ZONE CONTROL PANEL 68-0223-2 10 OPERATION Sequence of Operation On a call for heating or cooling, the zone damper stays open to the calling zone, and the dampers close to the zones that are not callin g. The TZ-3 panel brings on the heating or cooling and conditioned air is delivered to the calling zone until that zone is satisfied. When the call is satisfied, the s ystem 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. After purge, all dampers return to the Open position. An y zone thermostat can call for heating or cooling. If there are co-existin g calls for heat and cool, the panel first accepts the first call. Once that call is satisfied, or a maximum of 20 minutes has ela psed, the panel switches to allow the opposite call. On a call for heatin g or cooling, the heat LED illuminates red or the cool LED illuminates green. The zone damper LED turns green for the zone calling, and the dampers in the zones not calling close and turn red. As AOBD dampers move, the LEDs turn amber. Purge Mode At the end of every call for heat or cool, the panel enters a Purge mode that holds open the calling zone damper for three and one-half or two minutes. During this time, the panel or the HVAC e quipment can operate the fan. Purge also serves as a time delay to prevent short cycling of the heating and cooling equipment after each call. Purge LED lights to signal that the s ystem is in the Purge mode. Pressing the purge override button for two seconds overrides the Purge mode. Unless there is a new call for heat or cool during the Purge mode, all dam pers are moved to the Open position at the end of purge. Individual Zone Fan Control When all zones are satisfied, the Fan switch of each thermostat controls the fan operation for that zone. When the Fan switch is in the On position, the fan is energized, and the dampers close to zones where the Fan switch is in the Auto position. If there is a call for heat or cool during this time, the circulation mode ceases, and the heat or cool call is honored. When the zone callin g is satisfied, the circulation call resumes. Single and Multi-Stage Operation The panel can control up to three stages of heating and two stages of cooling. The first stage is energized by the thermostat. The second sta ge of heating is brought on by the thermostat, timer, or number of zones calling. The third stage of heating is brought on by the timer or number of zones callin g. The second stage of cooling is brought on by the timer or number of zones calling. The followin g instructions show how to configure the panel for stage control. If the e quipment is single stage, set the DIP switches as follows: 1st Stage by Thermostat, 2nd and 3rd Stages by Timer (Fig. 18) The thermostat controls the first stage of heat or cool. If the call is not satisfied b y the first stage within the time set on the timer, the panel energizes the second stage. If the call for heat is not satisfied by the second stage within the time set on the timer, the panel brings on the third stage. Set the DIP switches as follows: Fig. 18. Stage timer. 1st Stage by Thermostat, 2nd Stage Heat by Thermostat The thermostat controls the first stage of heat or cool and the second stage of heat. The timer controls the second stage of cool and third sta ge of heat. If the first and second stages combined do not satisfy the heat call within the time specified on the timer, the panel brings on the third stage of heat.
