(1)

: with the condensation control option, the limit is ‑10 °C.

(2)

: with rated indoor and outdoor air flows.

(3)

: the unit is able to run for a short period at temperatures below 10 °C to raise the temperature of the air in the air conditioned

room to 10 °C.

(4)

: at below ‑10 °C only the emergency heating resistor or hot water coil (optional) remains connected.
