The Z8 wireless zone controller is designed to replace outdated VVT, VAV, pneumatic, and dual duct systems. The Z8 is the rooftop AHU/HVAC controller with the ability to communicate with up to eight building zones using Pelican's powerful wireless mesh network. The Z8 utilizes intelligent built-in algorithms to deliver comfort, energy efficiency, and safety unlike anything available for zoning before.

Wireless HVAC Controller - Up to 8 Zones

Save money with built-in Intelligence

Upgrading to Pelican's zoning solution provides a centralized management tool for all your building zones. Your new Pelican control platform allows thermostat scheduling based on true demand.

 

Pelican's solution has built-in intelligence to further enhance energy reduction. Every Pelican zone thermostat can directly communicate with the Z8, so we can utilize an algorithm that resets AHU outputs to properly control temperatures in spaces. Pelican delivers controlled, comfortable, and safe environments from the AHU down to the zone level.

Know how your HVAC System runs Inside and Out

With Pelican's zoning solution, you gain central management as well as centralized historical trend data. Pelican's real-time tracking system records everything your HVAC unit does during operation. This makes it simple to identify the real problem when a complaint or issue arise. 

 

Items Pelican Tracks:

 

Space Temperature

Temperature Set Points

Space Demand (Heat & Cool)

Discharge Temperature

Return Temperature

Outside Air Temperature

Unit Output (Heat & Cool)

Stages Active (Heat & Cool)

Fan Running

How it all comes together.

Z8wireless

No communication wire required. The Z8 controls the HVAC unit and communicates with each Pelican thermostat over Pelican's wireless mesh network. Through this real-time communication, the Z8 properly sets the HVAC unit to provide A/C or Heat to the building zones in demand. Pelican thermostats (TS200, TS200H, TS250, or TS250H) open and closed 24 VAC damper actuators to bring the right conditioned air into each space.

 

The Wireless Module is used to communicate between the Z8 and its zones. One Z8 Wirelss Module can communicate with up to eight zones. It is removable allowing for ease of placement.
STATIC SENSOR:
Included with the Z8 is 20 feet of tubing and a static pressure sensor. The Z8 will modulate either a bypass or variable speed fan to maintain a target supply static based on readings and configured settings.
Three configurable temperature inputs are provided to track supply, return, outside air, and/or boiler temperatures. Probes are included with purchase of Z8.
STATIC AND ECONOMIZER MANAGEMENT:
A1 and A2 are 0 - 10VDC outputs for Bypass, Variable Speed Fan, and/or Economizer control

The Z8 provides complete static management, with built-in restart safeties. It also provides complete economizer control with economizer position feedback and fault detection.
CONTROL THE HVAC UNIT:
Y, W, G, W2, Y2, W3, Y3 - 24VAC Outputs

3H/3C Heat Pump or Conventional unit control.
The Z8 uses an intelligent built-in algorithm to actively decide how to stage up and down the AHU to maintain a proper discharge temperature based off true zone demand.
The Z8 can be installed inside the HVAC unit where it can easily be wired to control the air handler. The Z8 will properly stage up and down the AHU for both maintaining the correct discharge temperature and static pressure.
The wireless antenna is installed outside the HVAC unit or down in the building. The antenna cannot communicate through metal, so it is designed to easily be installed where metal will not block its signal. Once installed it will communicate with the Pelican Thermostats
A Pelican Thermostat (TS200, TS200H, TS250, TS250H) can control a 24VAC two-position or floating damper actuator. The Pelican thermostat is wired directly to the actuator.
The Pelican Thermostat (TS200, TS200H, TS250, TS250H) installed in the space is monitoring temperature and demand. It intelligently learns how its space reacts to the outputs of the HVAC unit. The Pelican thermostat continually communicating with the Z8 to make sure it is receiving the conditioned air it needs to keep its space comfortable.
The Pelican Gateway (GW400) must be installed to connect the Pelican devices to the Internet. From the Pelican Web App you will configure, monitor, and manage your entire zoned system.

Online Management and Fault Detection

 

Configure and manage the Z8 right from the Pelican Web App. Managing your entire zoned system from the Internet puts building comfort control into your hands. When a failure occurs, you receive an email or text alarm, directing you to your system and the issue. So you can immediately identify the problem and make resolutions proactively.  

Responsive Demand Management

 

The Z8 communicates wirelessly to each zone thermostat supplied by the AHU. With this communication link, the Z8 dynamically adjusts to the output required for optimal comfort in each zone. Pelican's continuous real-time analysis and feedback, puts controlling comfort, safety, air quality, and energy reduction under your control from virtually anywhere.

Responsive Static Management

 

With a built-in static input, the Z8 monitors duct static pressure to optimize the target static within your system. The Z8 offers from 0 to 10 outputs for either a Variable Speed Fan or Bypass Damper. Safety is provided for both high and low static to protect the duct work, coils, and AHU.

Historical Usage Tracking

 

The Z8 Internet connectivity provides real-time and historical information about the operation of the AHU during its lifecycle. Using Z8 historical graphs, pin-pointing issues and resolutions is simple without even stepping on-site. Save time and energy solving problems when they occur.

Advance Temperature Management

 

The Z8 is able to monitor demand from each zone and calculate the temperature output required by the AHU to properly maintain a comfort indoor environment. This logic delivers peace of mind since the system is able to address and determine how to adjust the system to best meet the building's needs.

Responsive Economizer Logic

 

The Z8 uses built-in advanced logic to analyze outside air temperature, space temperature, CO2 levels (if using a TS250), space demand, and VFD speed, to properly modulate the outside air damper. Logic and control adds energy efficiency, air quality, and comfort to a building's climate.

Simple Installation

 

The Z8 is easily installed. Install it close to the AHU so it becomes the controller. This eliminates the need to run wire between the Z8 and the HVAC unit. There is ZERO communication wire required to the zones. Each zone thermostat communicates to the Z8 wirelessly. Making retrofit easy and affordable.
