Room at 3:00 was pre-set at 19C of 66.2F. Was so cold, sneezed all night no sleep. Tried to reset, and set to 30, 86*. Nothing happened, fan keep blowing cold air. By checkout time at 12:00, temp got up to 23C or 73*. From 3:00 until check out with no air on temp warmed up only 7*....Thermostat does not stop fan from blowing cold presed air, even when I changed it to 30c. Never stay there again as they waste cold air for nothing. 66* is too cold for someone from Costa Rica.....maybe Alaska would be comfortable...........Not Happy !
