  Richard HarrisSep 2, 2025
  If your Toshiba Air Conditioner displays an error indicating that the outdoor unit inverter Idc is activated, it means short-circuit protection for the compressor drive circuit devices (G-Tr/IGBT) has been triggered. This could be due to issues with the IGBT, the outdoor unit P.C. board, inverter wiring, or the compressor itself, resulting in a complete system shutdown.

This document is the Owner's Manual for Toshiba Air Conditioners (Split Type), specifically for 4-way Cassette Indoor Units with model names RAV-HM561UTP-E, RAV-HM801UTP-E, RAV-HM901UTP-E, RAV-HM1101UTP-E, RAV-HM1401UTP-E, and RAV-HM1601UTP-E. These units are designed for commercial use and utilize R32 refrigerant.

Function Description

The Toshiba air conditioner is designed to provide cooling and heating for commercial spaces. It operates as a split-type system, with an indoor 4-way cassette unit and an outdoor unit. The system uses R32 refrigerant, which is an HFC (Hydrofluorocarbon) that does not destroy the ozone layer. The indoor unit features a suction air port where room air is drawn in, an air filter to remove dust, and a discharge louver that directs the conditioned air. The outdoor unit includes an air intake, air discharge, piping panel, wiring hole, and refrigerant pipe outlet.

The air conditioner is controlled via a wired remote controller (model RBC-ASCU1*). This controller allows users to:

Turn the unit ON/OFF.
Select the running mode (Auto, Heat, Dry/Dehumidify, Cool, Fan).
Adjust the fan speed (Auto, Low, Low+, Med, Med+, High, Fix).
Set the desired temperature within a range of 18.0°C to 29.0°C, with 0.5°C sensitivity.
Control the louver direction for air discharge, offering six steps for heating/fan mode and four steps for cooling/dry mode. An auto-swing function is also available.
Set a timer for the unit to turn off, with settings from 0.5 hours up to 24 hours.
Access a "Self Clean" mode to dry the inside of the indoor unit after cooling/dry/auto (cooling) operation, helping to keep it clean. The self-clean time varies from 1 to 2 hours depending on the prior operation duration.
View various indicators on the LCD, including running mode, central control, setting, repair, test run, temperature setting, wind direction, louver position, louver locking, fan speed, timer off, pre-heat, remote controller sensor, and notice displays.
Access troubleshooting history, which can record up to four past issues, displaying check codes and faulted indoor unit numbers.

The unit also features an 8°C heating operation mode for pre-heating, which requires specific settings via the wired remote controller.

Maintenance Features

Air Filter Cleaning: The air filters should be cleaned when the filter indicator is displayed on the remote controller. Clogged filters can reduce performance. This task should be performed by a qualified installer or service person due to working at heights.
Long-Term Storage: Before extended periods of non-use, it is recommended to perform fan operation for a few hours to dry the inside, then stop the unit, turn off the circuit breaker, and clean/reinstall the air filters.
Drain Pan Cleaning: The drain pan should be cleaned before the cooling season to prevent clogging, overflow, and potential water damage. This should be done by a dealer.
Periodic Checks: Regular maintenance (at least once a year, or every 3 months for units operating 8+ hours daily) is recommended for both indoor and outdoor units to ensure efficient operation and extend product life. This includes checking for dust/dirt clogging, abnormal sounds, vibration, damage, rust, and peeling of insulation/coat.
Professional Service: For any repairs, relocation, or complex maintenance tasks (e.g., electrical work, refrigerant handling, working at heights), it is crucial to contact a qualified installer or service person. Users are warned against attempting these tasks themselves due to safety risks.
Safety Precautions: Before any maintenance or inspection, the circuit breaker must be turned OFF to prevent electric shocks. Do not touch aluminum fins or rotating parts.
Environmental Considerations: Regular cleaning and maintenance contribute to environmental conservation by ensuring efficient operation.
