Hi All Ive got an Attic Breeze solar powered attic fan, its very simple. DC 24 V motor with 2 wires that connect to a small thermostat/hot temperature switch. When it reaches 24degrees from memory the motor cuts in and runs from Solar during the day to cool my attic, works a treat. What I want to do is now power the fan at night, I bought a DC plug pack and disconnected my Thermo switch and connected the plug pack - works great, spins its head off and cools the attic rapidly. What i want to do though is have BOTH connected, that is, have the fan operate on its thermo during the day but then remotely switch my plug pack on during the night. I can do this using home automation (openhab) with temperature rules Am I right in saying I can just connect the same plug pack wires onto the Thermo switch and then away it goes? I will try it during the day when I get a chance but i didnt want to kill anything Thanks!
