I think most hybrids commonly available should be warmth tolerant.

Miltoniopsis Culture
Quote:
Days should average 80-85°F (27-29°C), and nights should average 60-64°F (16-18°C), with a diurnal range of about 20°F (11°C). Plants can tolerate temperatures higher than 90°F (32°C) for brief periods, especially if humidity is high and air movement is strong. Some growers successfully cultivate Miltoniopsis with Phalaenopsis at night temperatures near 68°F (20°C). Other growers report success cultivating plants with Cattleyas at 55-58°F (13-14°C)
