- Bought this cheap window fan. Want to bypass the thermostat with an on/off button.
I bought this window fan for my work shed. Installed it on a nice, mild day. Next day fan wouldn't work. Almost took it back to the store before realizing the day was much colder. The fan is on a thermostat - one that's probably set for summer, not winter.
So, I want to be able to operate it in near-freezing temps. Rather than ripping out a perfectly good thermostat function, I'd like to just press a button to bypass it.
Plaque on back says it draws 120V and .7A. It has 2 independently-controlled fans, each with 0-1-2-3 settings. (Hopefully, the .7A is at max output). Thera are very small, low speed plastic fans.Here is the thermostat. It appears to be first in line in the circuit (or last. I haven't checked which side is hot yet). Before opening it up, I'd assumed the thermostat would be on a very low voltage part of the circuit, merely controlling a solenoid or something, but it turns out it's directly in the power circuit, and therefore I will need a 120v jumper and switch.
I don't know if there is a way to adjust the stat, not that I saw. That would solve my problem real quick.
I am thinking of putting in an on/off push button or toggle that will short circuit the thermostat if I want to the fan to be on at any temperature.
(The fan runs off the work shed power bar, so it will only be on when I am in there with the power on.)You guys always seem to come up with solutions I hadn't thought of.
