Another item with HVAC.
Using my Ocelot and some temp and one humidity sensor with insteon control I have lowered my use of air conditioned air in the evening and early morning. If the outside temperature and humidity are below the indoor setpoint I will shut down the HVAC air conditioning units , open dampers to outside air into the duct work for the two HVAC system after the air exchange units and then turn on the whole house fan at its low setting. This allows me to bring air into each room in the house through the registers without putting a negative strain on the house fan. Once the temperature set point for the inside air is reached or the outside air temp rises above the setpoint the system will shut down or revert to air conditioning control.
