Need simple thermostat to run 2 fans

Looked around on the web, couldn't find what I need.
I need a 110v thermostat, direct wire, that mounts in a single or square box. It will need to power on 2 very small fans at around 45 degrees and turn them off at 55 degrees, just a simple rotary temp selection knob would be fine. Didn't think it would be too hard to find but I guess I can't find the right place to look.

Most "simple" mechanical thermostats probably have easily +/- 5 slop on the setpoints, so for you application you need something using RTD's and digital circuits. Available, and not necessarily expensive. Do more google.

It's a line voltage thermostat for baseboard heaters.

Depends on what your application is. If you just need it to turn on somewhere between 40 and 50, and turn off several degrees higher, this might be ok.

you said 45o to 55o. That stops at 50o. Most tstat like that dont keep temp's to close.

At the top of this Forum, locate "Useful Electrical Sites", and locate the "Honeywell 'On-Line' catalog "

At the W-S select, select "product search" which is listed under" products."

"Scroll" the bar indentified as "Select the Product Family" to arrive at "Temperature Controllers", and then select that listing.

You will find numerous design choices for specfic applications and specfic types of control circuits, and also a choice of appox 50 different temperature ranges.
