To enhance accurate temperature reading, an optional Remote Indoor Temperature Sensor is available.
Mr. Slim models allow fresh air in through ducting connected to the indoor units. For advanced control of indoor air quality, interlocked operation featuring Lossnay Energy Recover Ventilators is also available. (This feature is not available on PKA (wall mounted) models.)
