Abstract
An automatic climate controller device identifies an operating zone of the climate control system according to at least two input factors, and identifies a discharge temperature of the climate control system. Based on the operating zone and the discharge temperature, the automatic climate controller device determines whether to perform at least one override action to override a climate control system setting to reduce the possibility of evaporator core icing. The automatic climate controller device also adjusts an evaporator set point according to the at least one override action to reduce the discharge temperature. The input factors may include evaporator temperature and cabin relative humidity. The actions may include one or more of increasing blower speed or increasing use of recirculated air.
