Resideo TAZ-4H Zone Panel
The Resideo TAZ-4H Zone Panel is a dedicated expansion solution designed specifically for the HZ432 TrueZONE system. For contractors managing large-scale residential or light commercial projects, the TAZ-4H add-a-zone panel provides a seamless way to scale beyond the base four zones. Each unit supports 4 additional zones, and by daisy-chaining or parallel wiring panels via the AZ1 and AZ2 terminals, technicians can expand a single system to support a maximum of 32 zones. This HVAC zoning expansion module eliminates the need for complex workarounds when the primary controller has reached its terminal capacity.
Built with technical efficiency in mind, the TAZ-4H/U features robust push terminals that accept 18- or 20-gauge solid wire, supporting up to two wires per terminal for simplified daisy-chaining. The integrated digital display uses real-language prompts to guide the installer through configuration, while common-sense LEDs provide immediate visual feedback on damper states (green for open/opening, red for closed/closing). The panel is compatible with conventional, heat pump (O/B), and multi-stage thermostats, though technicians should avoid thermostats utilizing phantom voltage or power-stealing modes without a dedicated C-wire connection. For reliable operation, ensure a 24 VAC transformer of 40 VA or more is used, maintaining proper phase alignment when sharing power with the HZ432.
High-Volume SEO Keywords: Resideo TAZ-4H Zone Panel, TAZ-4H add-a-zone panel, HVAC zoning expansion, TrueZONE HZ432 expansion, 4-zone expansion module. Key Benefits:- Scalable Architecture: Add 4 zones per panel to expand the HZ432 up to a total system capacity of 32 zones.
- Simplified Wiring: Utilizing only two wires (AZ1 and AZ2) to connect to the main HZ432 panel, significantly reducing installation time.
- Diagnostic Intelligence: Built-in checkout mode and status LEDs allow for rapid verification of damper logic and thermostat inputs without a multimeter.
- Universal Compatibility: Supports both 2-wire and 3-wire dampers with open/closed logic and works with standard 24V thermostats.
- Flexible Mounting: The low-profile design matches the HZ432 and can be mounted on a wall, stud, or return duct in any orientation.
Can the TAZ-4H be used with wireless thermostats?
To use RedLINK wireless thermostats with this expansion panel, a separate Equipment Interface Module (EIM) is required for each wireless zone. The TAZ-4H does not provide direct RedLINK wireless communication.
Does this panel require its own transformer?
While the HZ432 and TAZ-4H can share a transformer if the VA rating is sufficient to power all dampers and boards, best practice for large systems is to provide a dedicated 40 VA 24V transformer for the expansion panel.
How far can I run the communication wires?
Ensure the AZ1 and AZ2 communication lines are kept at least 12 inches away from line voltage wiring to prevent electrical interference. If crossing line voltage is unavoidable, use shielded cable for the AZ terminals.
