Thermostat Hack

Restaurants chains are controlling temperatures in remote eating places from offices in another state now.  Workers and customers are indoors in the cold with their coats on and thermostat control adjustments in locked clear plastics boxes.

So,  can we blow hot air into plastics lock box to get wall thermostat sensor control (variable resistor) to turn our air conditioning on?
  
Maybe blow cold air from our soft drink cup side to get the heating system turned on?

Anyone have ideas to share?

Hotels have been adjusting room temperatures from the check-in desk for years, reason there was too many adjustments being done to the temperature controllers wearing them out. It was simply a case of requesting that the temperature be adjusted, and it was. Having worked on AC systems, I found that everybody has a different idea of what is a good temperature. By experience it was found to be 23.5c to a max of 26c. If it is outside these limits the senior manager should be able to request the necessary adjustments be made.

Thanks for letting me know. I quit one restaurant this morning as eating my breakfast with my coat on is not desire.

there will be ntc thermistors on the walls behind panels. as the temperature increases, the resistance decreases, and a microcontroller somewhere in the building will be measuring it. short across the ntc with some wire to lower the resistance to fool it into thinking the temperature is too hot, or open circuit the ntc to fool it into thinking it's too cold
