Thermostat with limits set by landlord

[Wesley W.]

Hi folks,

I have a rental unit with a hot air/central AC system installed.  I am looking for a thermostat that I can install where I can set the upper and lower limits of the temperature - perhaps by a passcode.  In other words, a user can adjust/set the temperature up or down as long as it is within pre-set limits.

What I am really trying to do is to limit the low end of the temperature for the central AC in the summer.  The AC unit is pretty expensive, and I've had a tenant in the past whom liked to run the AC constantly with the windows open.  Even though they are paying for the utilities, it is putting excessive wear on the system and I worry it will fail prematurely, which would be my cost to bear.

Does such a product exist?

Thank you in advance.
