  If your Panasonic Remote Control isn't working with the ERV, check the power cord connection to ensure it's secure. Also, verify that the connection to the ERV is correct and that the wire connected to the ERV isn't loose.

This document provides installation and operating instructions for the Panasonic Remote Control for Energy Recovery Ventilator (ERV), Model No. FV-SWGR1.

Function Description

The Panasonic FV-SWGR1 is a remote control designed to manage Energy Recovery Ventilators (ERVs). It allows users to control various aspects of the ERV's operation, including power on/off, air volume, ventilation mode, and timer functions. The remote control can link up to 10 ERVs, making it suitable for managing multiple units within a system. It features an LCD screen for displaying operational status, time, and alerts, along with physical buttons for user interaction. The device supports RS485 communication for integration with centralized control systems, enabling more advanced monitoring and control capabilities.

RS485 Interference: Should be at least 1 m away from TV sets, broadcast radios, computers, etc., to avoid distorted images or noise.

Usage Features

The remote control offers a range of features for convenient ERV management:

Power On/Off: A dedicated Standby key allows switching the ERV between running and standby modes. The ERV will resume operation in the last mode used before being switched off.
Air Volume Adjustment: Users can switch the air flow volume between "Hi" (High) and "Lo" (Low) using the AIR VOLUME key. The LCD displays the current air volume setting with bars (shortest bar for Low, all three bars for High).
Ventilation Mode Selection: The HEAT EXCHANGE/NORMAL key allows switching between heat exchange mode and normal ventilation mode.
Clock Setting: The remote control allows setting the local time. The TIME indicator flashes when the time is not set and stays solid once set. The clock time display also flashes if not set.
Timer ON/OFF Function:
- Setting: Users can set specific times for the ERV to turn ON (TIMER ON) or OFF (TIMER OFF). This function requires the clock to be set first. The TIMER ON/OFF indicators stay solid once the timer is set.
- Air Volume for Timer ON: While setting TIMER ON, the air volume for the ERV can also be set.
- Cancellation: Timer settings can be canceled by simultaneously pressing the TIME and "✓" keys for 3 seconds, or by setting the hours or minutes of TIMER ON or TIMER OFF to " - ".
Filter Status Indicators:
- CLEAN FILTER Indicator: Flashes when the ERV has run for 720, 1440, or 2160 hours, indicating that the filter needs cleaning. The LCD displays F-1, F-2, or F-3 accordingly.
- REPLACE FILTER Indicator: Flashes when the ERV has run for 2880 hours, indicating that the filter needs replacement. The LCD displays F-4.
Filter Reset: After cleaning or replacing the filter, users can reset the indicators by pressing the "^" and "✓" keys simultaneously for more than 3 seconds. This clears the alert and recalculates the service duration.
LCD Backlight: The LCD backlight automatically turns off after 1 minute of inactivity and can be turned back on by pressing any key.
RS485 Connection Status: The CONNECTION icon indicates the status of the RS485 connection:
- Rapidly Flashing: Intranet connection underway.
- Solid On: Intranet connection successful.
- Off: No valid network signal detected (possible causes include no signal from centralized control, wrong wiring, broken line, or disabled RS485 function).
RS485 Function Enable/Disable: The RS485 function can be enabled or disabled by pressing and holding the TIME key and the "✓" key simultaneously for 3 seconds. A slow flash of the CONNECTION icon three times indicates disabling, while rapid flashing or solid on indicates enabling.
