The Z24 wireless zone controller is designed to replace outdated VVT, VAV, pneumatic, and dual duct systems. The Z24 is a rooftop AHU//HVAC controller that can communicate with up to twenty-four zones over Pelican's powerful wireless mesh network. The Z24 utilizes intelligent built-in algorithms to deliver comfort, energy efficiency, and safety unlike anything available for zoning before.
Wireless AHU Controller - Up to 24 Zones
Take a Look on the Inside
Save money, with built-in Intelligence
Upgrading to Pelican's zoning solution provides a centralized management tool to manage all your building zones. With your new Pelican control platform, you can accurately schedule thermostats to run based on true real-time demand.
Pelican's solution has built-in intelligence to further enhance energy reduction. Because every Pelican zone thermostat can directly communicate with the Z24, it can utilize an algorithm that resets AHU outputs to properly trend the temperature in each building space. This allows Pelican to deliver a controlled, comfortable, and safe environment from the AHU right down to the zone level.
Know how your HVAC System runs Inside and Out
Pelican's zoning solution gives you central management as well as centralized historical trend data. Pelican tracks everything that happens in your system in real-time, going on in your entire system. So, when there is a complaint you can quickly identify the problem.
Items Pelican Tracks:
Temperature Set Points
Space Demand (Heat & Cool)
Outside Air Temperature
Unit Output (Heat & Cool)
Stages Active (Heat & Cool)
Bypass Damper Position
Economizer Damper Position
How it all comes together.
No communication wire required. The Z24 controls the HVAC unit and communicates with each Pelican Thermostat over Pelican's wireless mesh network. Using real-time communication, the Z24 correctly stages the HVAC unit to provide A/C or heat to zones on demand. Pelican Thermostats (TS200, TS200H, TS250, or TS250H) open and close 24 VAC damper actuators to bring the right conditioned air into each space.
A1 and A2 are 0 - 10VDC outputs for Bypass, Variable Speed Fan, and/or Economizer control
The Z24 provides complete static management, with built-in restart safeties. It also provides complete economizer control with economizer position feedback and fault detection.
Online Management and Fault Detection
Configure the Z24 right from the Pelican Web App. Managing your entire zoned system from the Internet puts comfort right into your hands. When a failure occurs, you receive an emailed or text alarm, directing you to your system and the issue. You can immediately identify the problem and make resolutions proactively.
Responsive Demand Management
The Z24 communicates wirelessly with each zone thermostat supplied by the AHU. With this communication link, the Z24 can dynamically adjust the output required by the AHU to condition each zone correctly. With continuous trend analysis and feedback, the Pelican solution optimizes comfort, safety, air quality, and energy reduction for your zoned environment.
Responsive Static Management
With a built-in static input, the Z24 can monitor duct static pressure to optimize the target static within you system. The Z24 offers 0-10 outputs for either a Variable Speed Fan or Bypass Damper. Safeties are provided for both high and low static to protect the duct work, coils, and AHU.
Historical Usage Tracking
With Internet connectivity, the Z24 provides real-time and historical information about the AHU's operation. Using the Z24 historical graphs, you can pinpoint issues and resolutions without even stepping on site. You save on the time and energy required to solve problems when they occur.
Advance Temperature Management
The Z24 monitors demand from each zone. It calculates the temperature output required by the AHU to maintain indoor comfort correctly. This logic delivers peace of mind as the system can identify and determine how to automatically adjust to best meet a building's needs.
Responsive Economizer Logic
The Z24 uses built-in advanced logic to analyze outside air temperature, space temperature, CO2 levels (if using a TS250), space demand, and VFD speed to modulate the outside air damper correctly. Logic and control adds energy efficiency, air quality, and comfort to the building's climate.
You can easily install the Z24 close to the AHU so it becomes a controller. This eliminates the need to run wire between the Z24 and the HVAC unit. There is ZERO communication wire required to the zones. Each zone thermostat communicates to the Z24 wirelessly. Making retrofit easy and affordable.
