NOTE: Password to enter factory settings menu is 1234
Temperatures
– User can monitor various temperature values.
RH Values
– User can monitor various RH values.
Open/Closed Status
– Menu to view the open/closed status of all inputs.
Variable Values
– Allows the user to monitor all of the variable input and output values.
Blower VFD Status
– Live parameter feedback from the supply VFD.
Comp VFD Status
–
Live parameter feedback from the compressor VFD.
Refridge Diag
– This allows the user to monitor refrigerant components, pressures, and temperatures.
Outdoor Air Values
– Displays the high/low airflow limits. The calculated actual outdoor air percentage
will also be displayed.
ERV Diagnostics
– Displays ERV performance and diagnostic values.
• Current Performance
– Overview of ERV state, ERV wheel speed, exhaust fan speed, and wheel
differential pressure.
• Temp and RH
– Displays temperature and RH values for every quadrant. Also calculates enthalpy at
every point.
• ERV Pressure
– Real time values for monitoring ERV pressure parameters. Stores based values for
pressure faults. These values can be adjusted manually or through the ERV calibration process.
CFM
– Displays measured CFM readings. This readout is only valid for units with direct-drive wheels.
Test Menu
•
Test Fans
– Off, All, Supply, Exhaust, Powered Exhaust, Cond Fans.
•
Test Gas Heat
– Contains high and low fire tests.
•
Test Cool/HP
– Test cooling or heat pump system. Adjustments and parameters can be monitored
during testing.
•
Test Analog Heating
– This test will simulate a voltage input from a BMS system. The test will begin
at 0 volts. The up and down buttons allow for modulation of input.
•
Test Analog Cooling
– This test will simulate a voltage input from a BMS system. The test will begin
at 0 volts. The up and down buttons allow for modulation of input.
•
Evacuation Mode
– Only to be used when working on the cooling system. All refrigeration valves in
the circuit will be open during evacuation.
• Test Options
• Test Cabinet Heater
– Beginning this test will activate the cabinet heater on.
• Test Drain Heater
– Beginning this test will activate the drain heater on.
• Test Crankcase Heater
– Beginning this test will activate the crankcase heater on.
• Test OA Ctrl
– Beginning this test will create an output to the outdoor air control. The test will begin
at 0 volts. The up and down buttons allow for modulation of the output.
• Test Freezestat –
Test menu will allow user access to adjust setpoints to verify freezestat operation
in various types of ambient conditions.
Clear Fault History
– This will clear the entire fault history. If there is an active fault when cleared, that
fault will show up until it is fixed.
Set Clock
– Set day and time.
Calibrate Static PS
– Calibrates pressure sensor. Must disconnect all pressure tubes before calibration.
Calibrate CFM
– Calibrates pressure differential in the venturi to calculate approximate fan CFM. Must
disconnect all pressure tubes before calibration.
Calibrate ERV
– Calibrates pressure differentials across all filters and energy wheel.
ERV Service Mode
– Allows user to control damper, supply, and exhaust fans.
Update Factory Defaults
– This allows the original factory default settings to be overridden. When
confirming the updated settings, these settings will now be used when “Factory Reset” is needed.
Factory Reset
– Will reset board to factory commissioned settings.
