This document provides a comprehensive design and technical manual for the Fujitsu ASYG07-14KETF series (indoor units) and AOYG07-14KETA series (outdoor units) wall-mounted inverter heat pump air conditioners, utilizing R32 refrigerant.
Function Description
The Fujitsu ASYG07-14KETF / AOYG07-14KETA series offers both cooling and heating functionalities, operating as an inverter heat pump system. Key operational modes and features include:
- Operation On/Off: Basic control to power the unit on or off.
- Operation Mode Setting: Allows selection of various modes such as cooling, heating, dry, and fan-only.
- Set Temperature Setting: Users can adjust the desired room temperature.
- Fan Speed Setting: Multiple fan speeds (High, Med, Low, Quiet) are available for comfort and noise control.
- Airflow Direction Setting: Includes louver position adjustment (up/down) and swing function for optimal air distribution.
- Timer Operations: Features Off timer, On timer, Sleep timer, On/off program timer, and a Weekly timer for scheduled operation.
- Additional Functions:
- POWERFUL operation setting: For rapid cooling or heating.
- ECONOMY operation setting: To optimize energy consumption.
- 10 °C HEAT operation setting: Maintains a minimum room temperature of 10°C to prevent freezing.
- Room temperature indication: Displays the current room temperature.
- Fan control for energy saving: Adjusts fan operation to save energy during cooling.
- Outdoor unit low noise operation setting: Reduces outdoor unit noise for quieter operation.
- Wireless LAN Control: Allows remote control via a mobile app ("AIRSTAGE Mobile") on iOS or Android devices, providing control over most functions from outside the home. This requires a compatible wireless router (IEEE802.11b/g/n, 2.4 GHz frequency band, supporting WEP, WPA (PSK), WPA2 Personal (PSK), WPS).
- External Input and Output: Provides interfaces for external control and status monitoring.
- External Input: "Operation/Stop" mode or "Forced stop" mode can be selected. Supports both dry contact and applied voltage input signals (DC 12V to 24V, 1mA to 15mA). Input signal types can be "Edge" (alternate type switch) or "Pulse" (momentary type switch, pulse width > 200 msec).
- External Output: Provides operation status, error status, and indoor unit fan operation status. Output voltage is DC 12V ±2V (High) or 0V (Low), with a permissible current of 50mA.
- Group Connection: Up to 16 indoor units can be operated simultaneously with a single remote controller. Automatic address setting simplifies installation.
- Function Settings: Various settings can be adjusted via the wireless remote controller to adapt to the installation environment, including:
- Filter sign: Sets intervals for filter cleaning reminders (Standard, Long, Short, or No indication).
- Room temperature control for indoor unit sensor: Allows correction of the room temperature sensor reading (e.g., -0.5°C to -4.0°C or +0.5°C to +4.0°C).
- Room temperature control for wired remote controller sensor: Similar temperature correction for wired remote controller sensors.
- Auto restart: Enables or disables automatic restart after a power interruption.
- Room temperature sensor switching (Aux.): Selects between indoor unit sensor, wired remote controller sensor, or both.
- Remote controller custom code: Allows changing the custom code for wireless remote controllers to prevent interference with other units.
- External input control: Configures the behavior of external input signals (Operation/Stop mode 1 or 2, Forced stop mode).
- Indoor unit fan control for energy saving for cooling: Controls fan rotation when the outdoor unit is stopped during cooling.
- Switching functions for external output terminal: Configures the output terminal for operation status, error status, or indoor unit fan operation status.
