Inquiry (采购产品): in wall timer I am looking for a digital or mechanical in wall timer that would go to a maximum of 2-4 hours. The walls are poured concrete. Here is the problem, I have a studio apartment in St Thomas USVI that is rented out. Since I am paying the electric bill the A/C runs 24/7... I need a timer that will automatically shut off. Currently there is just a single wall switch in the box to turn it on/off. It is 220V. (Once the maid went in turned it on and it ran for 2 weeks straight with no one in it.) It should also be tamper resistant. What do you have to solve this problem? There are approx 100 units in our development that could use this product. I'm sure there are other developments on the island that would be interested in a product that could solve this problem. (Their electricity is not cheap...)
