What to do if my Energy Wall U-ERV 600 system does not power up?
If the system doesn't power up, check the following: * Confirm that the building has power. * Ensure the disconnect switch is in the "ON" position. * Inspect all power and communication wires, referring to the electrical schematic, and secure any loose connections.
Why is my Energy Wall U-ERV 600 system powering up, but not starting?
If the system powers up but doesn't start, consider these potential causes: 1. Verify that an enable command is being sent to the system via HMI, BMS, or wire input. 2. Confirm that all unit orientation settings are correct. 3. Check for loose or incorrect wiring by tracing back power and communication wires, consulting the electrical schematic, and ensuring all connections are secure. 4. Resolve any active faults that may be preventing the system from starting. 5. If the issue persists, the primary controller may be faulty and require replacement.
Why is the economizer on my Energy Wall U-ERV 600 Fan not functioning correctly?
If the economizer isn't working right, check these items: * Make sure the damper isn't installed backwards. If it is, remove it and reinstall it 180 degrees from its original position. * Verify the temperature sensors are wired to the correct quadrant, referring to the electrical schematics. * Ensure the economizer is enabled and configured as desired in the system settings.
What to do if my Energy Wall Fan's damper does not rotate?
If the damper isn't rotating, try the following: * Check for any obstructions blocking its movement. Manually move the damper to ensure free movement. Note the damper shaft has a uni-directional bearing that restricts rotation in one direction. * Make sure that an option that requires the damper is enabled (economizer, defrost, purge, etc.). * Verify the damper motor wiring is correct. * If the issue continues, the damper motor might be bad and need replacing.
What to do if the secondary unit or fan is not operating in my Energy Wall U-ERV 600 system?
If a secondary unit or fan isn't working, check the following: * Confirm the secondary unit wiring kit was installed according to the electrical schematic. * Inspect for loose or incorrect wiring by tracing back power and communication wires and verifying them against the electrical schematic. Ensure all connections are secure. * Check if the primary controller is auto-identifying each unit. If not, verify the wiring. If the issue persists, replace the secondary controller. * Ensure all unit orientation settings are correct. * The secondary controller may be bad and need replacing.
