How to troubleshoot a Panasonic FV-10VEC2R ERV that doesn’t work?
- E
  ericksonomarAug 6, 2025
  If your Panasonic Fan ERV isn't working, begin by checking if the power cord is securely connected. Also, ensure that the frame cover is properly closed and the main switch on the product body is turned on. Inspect the spring on the inside of the frame cover for any damage or deformation. Note that the ERV might be running on an interval according to the ASHRAE time setting, or it may have stopped automatically if the outdoor temperature is low (-22 °F (-30 °C)).

Why is my Panasonic FV-10VEC2R Fan louder than usual when defrosting?
- D
  Darren OrtizAug 18, 2025
  When the product runs in circulation mode for defrosting, the air volume will be more than setting. This will cause the sound to be slightly louder than during normal operation.

Overview

Function Description
Important Technical Specifications
Energy Performance (Reference at 100 CFM)
Usage Features
Maintenance Features

The Panasonic Energy Recovery Ventilator (ERV) is a sophisticated ventilation system designed to improve indoor air quality while minimizing energy loss. It utilizes two blower fans, each driven by a DC motor, engineered for extended service life and reduced energy consumption. For safety, the unit incorporates a thermal-cutoff.

Function Description:

The primary function of the ERV is to exchange energy between stale exhaust air (EA) and fresh outside air (OA). Unlike Heat Recovery Ventilators (HRVs), the ERV can also transfer humidity, making it effective in both heating and cooling climates. In heating climates, it transfers heat and moisture from the exhaust air to the incoming cold outside air, pre-warming and humidifying it. In cooling climates, it pre-cools and dehumidifies the incoming hot outside air. This tempering and treatment of ventilation air helps maintain a fresh indoor environment even when the primary heating or cooling system is not actively running. The unit includes electric dampers in both the EA and OA ducts to prevent backdrafting.

Important Technical Specifications:

Model No.: FV-10VEC2R
Dimensions (Unit: inches (mm)):

Weight: 50 lb (22.4 kg)
Operating Temperature Range: -22 °F (-30 °C) to 104 °F (40 °C)
ASHRAE Time Knob Settings: 10, 20, 30, 40, 50, 60 min/h (cycle operation)
Air Volume Settings (SA/EA Knob): 50-100 CFM

Energy Performance (Reference at 100 CFM):

Heating (32°F/0°C OA, 100 CFM):
- Power Consumption: 68W
- Sensible Recovery Efficiency: 73%
- Apparent Sensible Effectiveness: 77%
- Moisture Transfer: 0.71
Cooling (95°F/35°C OA, 100 CFM):
- Power Consumption: 42W
- Total Recovery Efficiency: 55%

Usage Features:

Control Panel:
- Main Switch: Powers the ERV on/off.
- ASHRAE Time Knob: Adjusts the operation cycle (e.g., "10" means 10 minutes ON, 50 minutes OFF). Factory default is 60 min/h (continuous operation).
- SA Knob: Sets the supply air volume (50-100 CFM). Factory default is 100 CFM.
- EA Knob: Sets the exhaust air volume (50-100 CFM). Factory default is 100 CFM.
Filter Indicator: Lights up after 3 months of accumulated running time (90 days), accompanied by a buzzer sound, indicating the need for RA and OA filter maintenance.
Running Indicator: Lights up when the product is operating.
Filter Reset Button: Resets the accumulated running time after filter maintenance. A long press (3 seconds) can toggle the buzzer sound on/off.
HVAC/AHU Connection (Optional): The unit can be integrated with an HVAC/AHU system, allowing the HVAC/AHU to turn on when the ERV is operating.
Wall Switch/Boost Switch Connection (Optional): Allows external control of the ERV's standby and running states. The boost switch enforces maximum airflow (ASHRAE: 60 min/h, SA:100 CFM, EA:100 CFM).
Defrosting Operation: When outdoor temperature is low (≤ -22 °F (-30 °C)), the ERV automatically stops operating to prevent freezing. It also restricts supply air volume when outdoor temperature is less than 14 °F (-10 °C) to protect the energy recovery core. The unit may run in circulation mode for defrosting, which can result in slightly louder operation and higher air volume than set.
Installation Flexibility: Can be installed using either a wall mount or chain mount method. Ductwork can be configured as simplified ducted (return method), partially dedicated ducted, or fully dedicated ducted.

Maintenance Features:

Routine Maintenance: Recommended every 2-3 months to prevent clogged filters and condensation due to reduced airflow.
Filter Cleaning/Replacement: OA and RA filters can be removed and cleaned with a vacuum cleaner. OA filters are suggested to be replaced every 6 months with Panasonic Model FV-FL0810VE1 or FV-FL1310VE1.
Energy Recovery Core Cleaning: The energy recovery core can be cleaned with a vacuum cleaner.
Access for Maintenance: The frame cover can be opened by unlocking latches. For easier access, the lock plate at the hinge can be rotated to remove the frame cover.
Condensation Discharge: In cold climates, remove the 4 plugs on the frame cover to discharge condensation before opening the frame cover.
Safety Precautions: Always disconnect power before maintenance. Wear gloves to avoid pinching fingers. Avoid using petrol, benzene, thinner, or other chemicals for cleaning. Do not immerse resin parts in water over 60 °C. Ensure the frame cover is properly closed and the internal spring is not damaged for correct operation.
