Sensor
Units with IR remote control model have 3 sensors as standard:
T1 Air intake sensor: measures the temperature on the
air intake and is used to determine the air intake or room
temperature.
T2 Water temperature/changeover sensor: determines the
medium temperature for changeover between cooling and
heating mode (with appropriate DIP switch setting)
T3 Heat exchanger sensor: determines the emperature of the
heat exchanger. The temperature needs to guarantee that the
cassette operates within the limits of operation (4-75 °C).
