Economizer comfort index control

摘要: A control circuit for a typical home heating and cooling system, including means to relative humidity, is shown. The includes standard 24 volt transformer in conjunction with thermostat selector switch fan switch. As common many systems, multiple speed blower included the higher being used during cycle. In addition relay normal operation of motor an economizer which activates when cool position ON cause run at high while compressor running low not running. humidity makes central air conditioning system responsive (RH) as well temperature, thereby maintaining acceptable nighttime "Comfort Index" reducing energy usage by much thirty-five percent.
