Im wondering what the return on investment would be on a progrmable thermostat. Its for a business with about 3000 sq feet of office space. There are 3 thermostats and I believe they are always set at about 70. The building is used from 7-530 monday-friday so I imagine the savings will be higher than it would be in a resendital since it is often vaccant. Since it is a business we would probably hire an electrican which makes our upfront cost higher, and our electricty rate is low (.059/kwh). I just wanted to get a decent idea on ROI before I bring up the idea. How hot/ cold can a building get. I assume letting the building hit 100 in the summer and 50 degrees in the winter wont hurt anything?

Do it. In the long run you'll end up saving money. Since there's so many variables, such as insulation R value, efficiency of heating and cooling units, and how much people are opening and closing doors.... there's no way to really "do the math" here. More than likely you'll realize a savings.

Look into a honeywell 8000 series commercial thermostat
There might be federal or state incentives to install them as well. Basically you want a commercial thermostat for the occupied/unoccupied and lockout feature I would think your ROI would be just a few months. I personally would only throttle it back 4-6 degrees during the week and maybe 10 at the most on the weekend. |

If you let it get too far away from the regular temp the recovery is time consuming and the units run for so long that it becomes a wash. You shouldn't need an electrician just match up the colors to the letters they came from. Grove |
