The Rinnai Split Type Wall Mounted Air Conditioner is a residential and light commercial appliance designed for achieving consumer comfort. It uses R32 (difluoromethane) refrigerant, a flammable gas, and must be handled by a refrigeration mechanic with appropriate Australian refrigerant handling license. The appliance is available in several system models, including HSNRQ25B, HSNRQ35B, HSNRQ50B, and HSNRQ70B, with corresponding indoor (HINRQ) and outdoor (HONRQ) unit models.

Function Description

The air conditioner provides cooling, heating, dry (dehumidifying), and fan-only modes of operation. It features both basic and advanced controls via a remote control unit.

Basic Operations:

On/Off: Turns the appliance on or off, retaining the last operational settings and modes.
Cooling: Operates the air conditioner as a cooling appliance, with a temperature range of 16°C to 32°C in 0.5°C increments.
Heating: Operates the air conditioner as a heating appliance, with a temperature range of 16°C to 32°C in 0.5°C increments.
Fan Speed: Adjusts fan speed to AUTO, LOW (2 bars), MEDIUM (4 bars), or HIGH (6 bars).
Adjusting Vertical Air Flow (SWING‡): Activates continuous cyclic movement of the louvre or sets it to a fixed direction.
Adjusting Horizontal Air Flow (SWING↔): Activates continuous cyclic movement of the vanes or sets it to a fixed direction.

Advanced Operations (accessed by opening the remote control door):

Mode - Auto: Automatically adjusts fan speed, temperature, and operational mode (cooling, dry, or heating) based on room temperature.
- ≥ 27°C: Cooling Mode, Set Temperature 24°C
- 20°C ~ 27°C: Dry Mode, Set Temperature 24°C
- ≤ 20°C: Heating Mode, Set Temperature 24°C
Mode - Dry (Dehumidifying): Removes excess moisture from the room, automatically adjusting temperature and fan speed to maintain optimal humidity.
Mode - Fan Only: Circulates room air without changing the temperature.
Turbo: Rapidly cools or warms rooms at the fastest rate, operating the fan at maximum output. Not available in AUTO, FAN, or DRY modes.
Quiet: Operates the appliance at its lowest noise level, ideal for minimal noise requirements. Only available in COOL or HEAT modes.
Health (WiFi): Activates or resets the WiFi module when pressed 8 times in quick succession.
Sleep Mode: Automatically adjusts the set temperature over a 10-hour period to maintain comfort and save energy. Not available in FAN only mode.
