resideo TAZ-4H Add A Zone Panel Instruction

APPLICATION

The TAZ-4H is a zone panel used to add zones to the HZ432.
See Fig. 1. The HZ432 provides up to four zones. Each TAZ4H can add up to four additional zones for a total of 32 zones.

INSTALLATION

When Installing this Product

Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.
Check the rating given in the instructions and on the product to make sure the product is suitable for your application.
Installer must be a trained, experienced service technician.
After installation is complete, check out product operation as provided in these instructions.
Follow local codes for installation and application.

CAUTION
Voltage Hazard. Can cause electrical shock or equipment damage. Disconnect power before beginning installation.

Location

Select a location for the TAZ-4H as close as possible to the HZ432 panel.

Mounting

The TAZ-4H can mount on a wall, stud, or return duct

Wiring

CAUTION
Electrical Interference Hazard. Running cable near line voltage can interfere with panel operation.
Run cable connecting AZ terminals at least 12 in. from line voltage wiring.

IMPORTANT Be sure AZ1 and AZ2 wires do not cross and are a minimum of 12 in. from any line voltage wiring. If not possible, use shielded cable for AZ1 and AZ2 wires.
NOTE: Only two wires are required to connect the TAZ-4H panels to the main HZ432 panel. If more than oneTAZ-4H is used, each TAZ-4H can be wired in a daisy chain or parallel to each other, connecting the AZ1 and AZ2 terminals between panels. Each AZ1 and AZ2 terminal can fit two wires to simplify daisy chain wiring.

Connect the AZ1 and AZ2 terminals on both panels using standard 18 gauge thermostat wire:

Connect AZ1 on the HZ432 to AZ1 on the TAZ-4H AddA-Zone panel. See Fig. 5.
Connect AZ2 on the HZ432 to AZ2 on the TAZ-4H AddA-Zone panel. See Fig. 5.
Connect a 24V, 40 VA transformer to terminals R and C. R is Hot and C is 24 Vac (Common). See Fig. 4.
Connect thermostat wiring as shown in Fig. 7 through Fig. 11.
Install dampers using instructions provided with dampers.
Connect dampers to zone panel. See Fig. 6.
NOTE: Multiple dampers can be wired in parallel.

CONFIGURATION

To Enter Configuration

Press the Mode button once (the Config LED will light up).
Use the Back and Next buttons to navigate through the configuration settings. Scroll through the selection choices by using the “Adjust Setting” Left and Right arrow buttons. Pressing Next enters the selected option for that menu item and advances to the next menu.
The flow chart below illustrates TAZ-4H zone panel configuration.

HOME MODE

The display at home mode will either indicate communication is good or at least one zone is failing to communicate to the HZ432 zone panel. The TAZ-4H panel is factory configured for zones 5-8 with conventional thermostats, so it will indicate communication status as soon as it is powered even if it has not been configured.

CHECKOUT

To Enter Checkout

Press the Mode button twice (the Checkout LED will light up).
The Chart below shows the Checkout options and information shown. Use the Back and Next buttons to navigate through the checkout options. When testing a damper use “Adjust Setting” Left and Right arrow buttons to open or close the damper. Pressing Next advances to the next menu.

Troubleshooting

Table 6. Troubleshooting

Problem	Description
TAZ-4H does not communicate to HZ432	Verify HZ432 is configured for 4 zones + ADDZONE in the configuration settings. Verify the TAZ-4H is configured for the correct zones. If two TAZ-4H panels are used, we would expect one of the pan- els to be configured as zones 5-8 and the other to be configured as zones 9-12. See the configuration section in this guide. Verify the wiring connections on AZ1 and AZ2 are good. AZ1 from TAZ-4H should be matched to AZ1 on HZ432 and AZ2 from TAZ-4H should be matched to AZ2 on HZ432. You can fit two wires per terminal if multiple TAZ-4H panels are used and these can be wired in parallel or daisy chained. Verify the transformers powering the HZ432 and TAZ-4 are in phase. What is the DC voltage at AZ1 and AZ2? (It should be about 12.) If it is below 9 VDC, remove the wires at the HZ432 and measure the voltage at those terminals on the HZ432. For further troubleshooting, call the zoning hotline at 800-468-1502.
Damper is in wrong position	When the HZ432 is in idle mode (no call for heat, cool, or fan and not in purge), we would expect all dampers on the TAZ- 4H to be open and all the zone lights to be green. If the HZ432 indicates a call for cool, all zones on the TAZ-4H calling for cool at that time should have a green zone LED and have approx. 24 volts AC from M1 to M4 (open). All zones not calling for cool at that time should have a red zone LED and have approx. 24 volts AC from M1 to M6 (closed). If the HZ432 indicates a call for heat, all zones on the TAZ-4H calling for heat at that time should have a green zone LED and have approx. 24 volts AC from M1 to M4 (open). All zones not calling for heat at that time should have a red zone LED and have approx. 24 volts AC from M1 to M6 (closed). For further troubleshooting, call the zoning hotline at 800-468-1502.
When one of the zones on the TAZ- 4H calls for heat or cool, the HZ432 stays in idle (no heat, cool, or purge light lit).	Verify the settings and wiring are correct as described in “TAZ-4 does not communicate to HZ432” above. Go into Checkout mode and see what the TAZ-4 shows for the inputs from the thermostat on that zone. Verify the ter- minals energized are as expected. For example, if zone 5-A shows inputs on W1 and Y1, and that zone is configured for a conventional thermostat, there is a problem. A conventional thermostat should not energize W1 and Y1 at the same time. This could be caused by a shorted wire, a miswired thermostat, or a misconfigured thermostat. For further troubleshooting, call the zoning hotline at 800-468-1502.
