Coordinate Multiple Thermostat's Demands to a Centralized Equipment Controller for Unified Operation.

The Pelican zoning solution‘s basis of design is built around incorporating multiple zone thermostat’s demands to directly affect what is active at equipment that is common to all zones. 

Pelican uses their wireless mesh technology to establish real-time communication between multiple Pelican thermostats to one or more Pelican zone coordinators: the Z8 or Z24. This real-time transfer of information turns a seemingly separate mechanical system into a single efficient ecosystem.

As zone thermostats adjust their demands (heating, cooling and/or ventilation), the zone coordinator will optimize the output of the equipment it is controller to properly affect the overall building’s climate.

 

 

 

 

 Common Air Handler Applications

Variable Air Volume & Temperature (VVT) Air Handler Coordinator

In Variable Air Volume and Temperature (VVT) applications, a Pelican Zone Coordinator (Z8 or Z24) manages a central air handler to provide heating, cooling, and ventilation to multiple zones, and a bypass damper to maintain the correct amount of airflow going into active zones.  Multiple Pelican zone thermostats (TC or TS Series) will open, close, or float their own zone damper to allow heating, cooling, and/or recirculated/ventilated air into its space to maintain the room’s set-points.

Variable Air Volume (VAV) Air Handler Controller and Coordinator

In Variable Air Volume (VAV) applications, a Pelican Zone Coordinator (Z8 or Z24) manages a central air handler to provide cooling and ventilation to multiple ducted zones; in some applications central heat is also available. The zone coordinator  also modulates one or more variable speed fans to maintain the correct amount of airflow going into active zones. Multiple Pelican zone thermostats (TC or TS series) will open, close, or float their own damper to allow central air into the room. Some or all thermostats will have a local reheat capable of heating the incoming air to maintain the room’s set-point.

Mixing Box Air Handler Controller and Coordinator

In Mixing Box applications, a Pelican Zone Coordinator (Z8 or Z24) manages a central air handler to provide cooling and ventilation to multiple zones through one supply duct and central heating and ventilation to multiple zones through a second supply duct. Multiple Pelican zone thermostats (TC or TS series) will adjust the position of a single zone actuator, which moves two mechanically linked dampers, to either bring cold air or hot air into the zone to maintain the room’s temperature set-points.

Dual Duct Air Handler Controller and Coordinator

In Dual Duct applications, there are two Pelican Zone Coordinators (Z8 or Z24) installed. One coordinator manages the temperature output of one supply duct to provide cooling and ventilation to multiple zones. And a second coordinator manages the temperature output of a second supply duct to provide heating to multiple zones. In this application one of the zone coordinators also modulates one or multiple variable speed fans to maintain the correct amount of airflow going into active zones. Multiple Pelican zone thermostats (TC or TS series) will open, close, or float two separately actuated dampers, where one damper opens to provide heat and the second damper opens to provide cooling into the room, to maintain the thermostats set-points.

| Common Water-Plant Applications

Boiler Controller and Coordinator

In applications, where there are one or more boilers, a Pelican zone coordinator (Z8 or Z24) can be used to enable and reset the output of the boiler(s). The most common applications are WSHP condenser water-loops and two-pipe or four-pipe climate systems.

Cooling Tower Controller and Coordinator

In applications, where there are one or more cooling towers, a Pelican zone coordinator (Z8 or Z24) can be used to enable and reset the output of the cool tower(s). The most common application is a WSHP condenser water-loops.

Chiller Controller and Coordinator

In applications, where there are one or more chillers, a Pelican zone coordinator (Z8 or Z24) can be used to enable and reset the output of the chiller(s). The most common applications are for two-pipe or four-pipe climate systems.

| Additional Application

Exhaust Fan Building Pressure Controller

In application, where one or more exhaust fan are installed, the Pelican zone coordinator (Z8 or Z24) can be used to maintain a slightly positive building pressure through enable and modulating either an exhaust fan or an exhaust damper.

 

 

EXTERNAL INPUTS:

(T1, T2, T3) 10K Type II or Dry-Contact

Pull in up to three external temperatures. Most commonly discharge, return, and/or outside temperatures. *A forth external temperature sensor can be added to a Z8 or Z24 by wiring a Pelican TA1 to the controller's R, C, D terminals.

DIFFERENTIAL PRESSURE INPUT

(HIGH & LOW) Pressure Sensor

Connect a pressure tube directly into the built-in differential pressure inputs of the Z8 and Z24. The controller will monitor this pressure and make equipment adjustments to maintain targeted settings.

MODULATING OUTPUTS

(A1, A2, A3, A4) 0 - 10 VDC Signals

Four modulating outputs that are most commonly used for outside damper, variable speed fan, bypass damper, and/or modulating temperature control.

ANALOG INPUTS

(S1, S2) 0 - 10 VDC Signal

When used as an outside air damper controller, the Z8 and Z24 accepts a feedback signal to confirm the outside damper is in the correct position.

CONNECTION TO ANTENNA

(R, C, D) 3-Wires Only

The Z8 and Z24's output module can be installed at the equipment it is controlling and its Antenna in another location. The two devices communicate over a three wire connection. This is also the 24VAC power input for the Pelican controller.
R: 24 VAC, C: Common, D: Data.

DIGITAL OUTPUTS

(Y, Y2, Y3, W, W2, W3, G, G2) HVAC Unit Control

The Z8 and Z24 will enable the equipment's heating, cooling, and fan stages through standard 24VAC outputs. During an economizer or demand ventilation cycle, the (G2) output can be used to turn on exhaust fans or open a damper.​
