The following flow chart illustrates Z8 static configuration options.
ECONOMIZER CONFIGURATION OPTIONS
5
The following flow chart illustrates Z8 economizer configuration options.
DAMPER VOLTAGES
Settable range is from 0 to 10 VDC.
Verify settings match actual actuator
OPEN/CLOSED positions.
VARIABLE DAMPER [ON]
HIGH LIMIT SHUT OFF [°F]
ACTIVATION DIFFERENTIAL [°F]
FIXED ENTHALPY LIMIT [ON/OFF]
VARIABLE DAMPER [ON/OFF]
ECONOMIZER [ON]
DAMPER VOLTAGES
OPEN [VDC] CLOSED [VDC]
MINIMUM DAMPER POSITION [%]
DEMAND VENTILATION [ON/OFF]
TRACK DAMPER POSITION [ON/OFF]
MINIMUM OPERATING SPEED
Settable range 0% to 100% of
maximum fan speed. Configure to the
slowest fan speed allowed for proper
operation of the mechanical equipment.
Output: 0% = 0.0VDC
100% = 10.0VDC
DAMPER VOLTAGE
Settable range is from 0 to 10 VDC.
Adjust the settings to match the actual
OPEN/CLOSED end of travel positions
of the actuator being used.
MINIMUM DAMPER POSITION
Settable range is from 0% to 100% of
the maximum damper open position.
TRACK DAMPER POSITION
If the feedback input on the Z8 is being used for
economizer damper position feedback, turn this feature
ON. This will enable fault detection and diagnostics. In
some States fault detection and diagnostics are required
to meet energy codes. Check with your local and State
codes to determine if this is required for your installation.
DEMAND VENTILATION
If a Pelican Zone Thermostat with an
integrated CO2 sensor is installed and you
would like the Z8 to provide demand
ventilation based on CO2, turn this feature
ON.
TARGET OPERATING STATIC
Settable range 0.0 inch WC to 3.0 inch WC. This
sets the static pressure targeted when running a
cooling or heating cycle.
TARGET CIRCULATION STATIC
Settable range 0.0 inch WC to 3.0 inch WC. This
sets the static pressure targeted when running a
ventilation cycle.
MINIMUM STATIC
Settable range 0.0 inch WC to 3.0 inch WC. This
is a safety and will place the Z8 into an automatic
reset if detected during a heating, cooling or
reheat cycle. Reset will de-energize any calls for
heating, cooling, or reheat, but the call for fan will
remain energized. The Z8 will restart the heating,
cooling, or reheat cycle after ten minutes.
MAXIMUM STATIC
Settable range 0.0 inch WC to 3.0 inch WC. This
is a safety and will place the Z8 into an automatic
reset if detected during a heating, cooling, reheat,
or ventilation cycle. Reset will de-energize all
calls. Z8 will restart heating, cooling, reheat, or
ventilation cycle after ten minutes.
HIGH LIMIT SHUT OFF
Sets the warmest air allowed for economization. If
left blank, the Z8 will auto-calculate the high limit
shut off. Settable range of -20°F to 180°F.
ACTIVATION DIFFERENTIAL
Requires the outside air temperature to be at least
this many degrees below the return air temperature
to be used for economization. Settable range 0°F to
6°F.
FIXED ENTHALPY
Set to ON if the economizer should be disabled if
the outside enthalpy levels exceeds 28 Btu/lb. (No
enthalpy probe required to use).
