Is there a straightforward way to add a thermostat to an existing (basic no-frills) whole-house fan? I'd like to be able to set it to shut off when the outside temp rises to a certain point--so that the fan shuts off automatically in the early morning.
A simple timer would probably be fine. Could the fan easily be wired to an off-the-shelf HVAC thermostat? (...and program the thermostat to turn off the fan at X a.m. if the indoor temp is above 0 degrees, say...) There is an existing central HVAC thermostat that could be replaced or added to if needed.
