Operating Ambient
The minimum outdoor operating ambient in cooling mode is 55_F (12.78_C) without low ambient cooling enabled, and the maximum outdoor operating ambient in cooling mode is 125_F (51.67_C). At line voltage of 208v (or below) and an outdoor ambient of 120_F (48.9_C) (and above), the compressor operates in low stage. On Evolution communicating systems ONLY, low ambient cooling operation is possible at ambient as low as 0_F
The maximum outdoor operating ambient in heating mode is 66°F/18.89_C on all models.
