COMPONENT INSTALLATION LOCATIONS
The Z8 is not waterproof, but is designed to operate in environments from -20
˚
F to 140
˚
F. If installed outside, the Z8 must be installed inside of the HVAC unit or in a plastic waterproof case outside of the HVAC unit.
The Z8 comes with a wireless communicator (Wireless Module) which it uses to communicate with Pelican’s wireless network. Wireless signals will not communicate through metal, so if the Z8 is installed inside of an enclosed metal HVAC unit or box, you will need to remove the Wireless Module and install it outside of the metal enclosure. (NOTE: If the Z8 is installed inside of a building and/or is not enclosed in metal, you do not need to remove the Wireless Module).
The Wireless Module is water and weather proof. Install the Wireless Module onto a PLASTIC electrical box with the provided gasket placed in between to keep water out. Using three wires, connect the Wireless
Module’s D, C, and R terminals to the Z8’s D, C, R terminals (illustrated on page 7). The Wireless Module can be wired up to 500 feet away from the Z8 with non-shielded wire.
If the roof has a metal decking, install the Wireless Module below the metal roof line so that the wireless can reach into the building.
The illustration on the next page shows where to mount the Z8 and the Wireless Module if installing inside a rooftop HVAC unit.

SYSTEM ONLINE SETUP
All configuration is done Online using the Pelican Site Manager. A Pelican Gateway must be installed, connected to the Internet, and able to wirelessly communicate with a Z8 OR Z24 to access the zone controller’s configuration options. Power must be provided to each product to configure.
Step 1: Install a Pelican Wireless Gateway, setup a Pelican Site Manager, and log onto your Pelican Site
Manager using a Web browser on any Smartphone, Tablet, or PC.
Step 2: Install the Z8 or a Z24 following their proper installation guides.
Step 3: Follow the Damper Install guide and install all TS200, TCM1, and/or RT1-DC/AC. All devices will automatically connect with the Pelican Gateway. You will recieve a new notification on your Pelican Site
Manager identifing that new product have been installed. Select Configure on the far right of the product you want to setup.
Step 3: Name the Device.
Step 4: Follow the configuration guides below to properly configure the Z8.
Step 5: Once everything is installed, setup, and configured, proceed to page 26 for start-up process.
SYSTEM OPERATION CONFIGURATION
System Type: Set to Conventional or Heat Pump
AUXILIARY HEAT: Set to Disable to not use or if there is no auxiliary heat. Set to Auxiliary to utilize auxiliary heat, if needed. Set to Emergency to recieve a notification if the auxiliary heat is used.
Heat Stages: Set to the number of available heat stages.
Cool Stages: Set to the number of available cool stages.
Fan Stages: Set to the number of available fan stages.
IMPORTANT:
If the Variable Speed Fan is self regulating or it is being controlled by another controller, and you want the
Z8 to tell the other controller when to turn the Variable Speed Fan On and Off - set Fan Stages to ‘1’.
If the Z8 is controlling a 0-10VDC Variable Speed Fan - set Fan Stages to “Variable”.
Heat Needs Fan: Set to YES if the Z8 needs to call for FAN when it calls for HEAT.
20
VARIABLE SPEED FAN CONFIGURATION OPTIONS
SET VARIABLE SPEED FAN TO ON TO CONTROL A 0-10VDC VARIABLE SPEED FAN.
Minimum Operating Speed: Set the minimum required operating fan speed for when Heat or Cool is being called. This is set as a percentage of maximum available speed.
Configuring STATIC PRESSURE identifies how the Z8 should manage the bypass damper.
IMPORTANT: If the Variable Speed Fan is self regulating or it is being controlled by another controller, and you want the Z8 to tell the other controller when to turn the Variable Speed Fan On and Off - set Variable
Speed Fan to OFF and instead, set Fan Stages, under System Operations, to ‘1’.
BYPASS CONTROL CONFIGURATION OPTIONS
SET BYPASS CONTROLLER TO ON TO CONTROL A 0-10VDC MODULATING BYPASS DAMPER
ACTUATOR.
Damper Voltages: Set the output voltage range for opening and closing the bypass damper. This is most commonly either 0-10VDC or 2-10VDC:
Open: Set to the voltage output for fully open.
Closed: Set to the voltage output for fully closed.
Configuring STATIC PRESSURE identifies how the Z8 should manage the bypass damper.
STATIC PRESSURE CONFIGURATION OPTIONS
CONFIGURE STATIC PRESSURE BASED ON THE REQUIREMENTS OF YOUR SYSTEM DESIGN.
Target Operating Static: Set to the targeted static pressure for running Heat or Cool. The Z8 will modulate either a bypass damper or a variable speed fan with the goal of maintaining this target static.
Target Circulation Static: Set to the targeted static pressure for running FAN. The Z8 will modulate either a bypass damper or a variable speed fan with the goal of maintaining this target static. Setting the
Circulation Static lower than the Operating Static allows for a quiter operation when only FAN is requested by the zones.
Minimum Static: Set the minimum static pressure for when Heat or Cool is being called. The Z8 use this setting to protect the HVAC unit. If Minimum Static is detected, during a call for heat or cool, the Z8 will immediatly turn off the compressor, preventing the coils from freezing over. The Z8 will also generate a
Notification.
Maximum Static: Set the maximum static pressure for when Heat or Cool is being called. The Z8 use this setting to protect the ducts. If Maximum Static is ever detected, the Z8 will immediatly turn off the entire system, preventing the ducts from being damaged; it will then go into a 10 minute reset cycle. The Z8 will also generate a Notification.
21
ECONOMIZER CONFIGURATION OPTIONS
SETTING ECONOIMZER TO ON PROVIDES TWO OPTIONS:
1) If the Economizer is controlled by the HVAC unit or a seperate controller, but you
to ON and set a High Limit Temperature.
want the Z8 to notify the seperate controller if the zones needs or can use outside air: turn
2) If the Z8 is directly controlling a 0-10VDC Economizer damper actuator, turn
VARIABLE DAMPER to ON.
High Limit Temperature: Set to maximum outside air temperature. Above this temperature the Economizer will be disabled.
Variable Damper: Set to ON if the Z8 is directly controlling a 0-10VDC Economizer damper actuator.
Damper Voltages: Set the output voltage range for opening and closing the economizer damper actuator.
This is most commonly either 0-10VDC or 2-10VDC:
Open: Set to the voltage output for fully open.
Closed: Set to the voltage output for fully closed.
Minimum Damper Position: Set the minimum damper position for fresh air ventilation.This is set as a percentage of the maximum open position.
TEMPERATURE SENSER CONFIGURATION OPTIONS
THE Z8 USES THESE TEMPERATURE INPUTS TO PROPERLY CONTROL AND MONITOR THE ENTIRE
HVAC SYSTEM.
Input Sensor T1: Defaulted as Supply Air, but can be configured for various temperature inputs.
Input Sensor T2: Defaulted as Return Air, but can be configured for various temperature inputs.
Input Sensor T3: Defaulted as Outside Air, but can be configured for various temperature inputs.
INPUT POWER CONSUMPTION
To be able to record actual HVAC consumption, fill in each Stages energy consumption in either KW, BTU,
TON, or WATT.
If you set to TON, Pelican will calculate KW consumption based on a 13 EER rated HVAC unit.

Operation
1. Thermostats request cooling using the wireless network.
2. The Zone Controller energizes compressor stages when cooling demand is present.
3. In single duct systems, compressor stages are automatically held off if heating is active. This will continue until heating demand is satisfied.
4. Compressor stage outputs (Y, Y2, Y3) are energized based on system configured cooling stages and differential temperature between supply and return air. Target supply and differential temperature are adjusted automatically based on feedback from zoned thermostats and active settings in each zone.
5. Damper controllers are notified using wireless signals when they can open or close based on the availability of cool air in the system.
Safeties
Built-in system safeties such as coil temperature and internal pressure should be left in place since the Zone
Controller does not have provisions for monitoring or acting on these items. The Zone Controller does augment the built-in safeties in the following way:
1. Compressors will be shut down if the duct static pressure falls below acceptable levels.
2. A 4 minute short cycle timer is enforced for each compressor.
3. If all zone dampers are closed the compressors will be shut down.

3. If variable speed fan control is enabled the Zone Controller will maintain target static pressure based on measured static pressure from it's integrated pressure sensor.
4. Target static pressure can be configured for different levels depending on whether simple air circulation is active or heating/cooling is active.
5. Damper controllers are notified using wireless signals when they can open or close based on the availability of air in the system.
Safeties
Built-in system safeties should be left in place since the Zone Controller does not have provisions for monitoring or acting on these items. The Zone Controller does augment the built-in safeties in the following way:
1. The fan will be shut down if the duct static pressure exceeds acceptable levels.
2. If all zone dampers are closed the fan will be shut down.

Operation
1. The economizer is operational during cooling cycles and ventilation cycles.
2. During operational mode, the economizer will always open to at least the minimum open position to provide outside air for ventilation.
3. When the fan is off, the economizer will be fully closed.
4. The economizer will compare supply, return and outside air temperatures to automatically regulate the mix of outside and return air entering the system.
5. The Variable damper control output will modulate the economizer damper to adjust the air mixture.
Note
1. The economizer controller does not monitor building static pressure. A separate system should be implemented to manage proper building static pressure.
2. The Economizer controller can be optionally used to signal a built-in economizer to open or close using only the G2 output signal of the Zone Controller.
3. The economizer will hold off cooling compressor stages if outside air temperature is sufficiently low to allow building cooling to be satisfied.

Duct Static Pressure
Outside Pressure
Operation
1. The bypass is operational during heating, cooling and ventilation cycles.
2. When the system is not active the bypass controller will position the damper in the fully open position.
3. When the system is fully operational, the bypass damper will be gradually closed until the target static pressure is achieved.
4. As the static pressure varies due to changes in active zones the bypass damper will be automatically modulated to maintain the target static pressure.
Operation with Variable Speed Fan
1. The bypass will start in the half-open position.
2. The bypass will close if the variable speed fan is able to maintain proper static pressure.
3. If the variable speed fan is running at it's minimum setting and the static pressure exceeds the target static pressure, the bypass controller will open the bypass damper to maintain target static pressure.
