My boyfriend works for the local county government but not in an office or anything like that. He works for the building service department since he is a certified electrician by trade. His task is make sure that any electrical problems are resolved–that includes maintaining the Heating and A/C system. Located in the basement of the town hall, it is fully electric and is monitored in a control room. At least they have invested in a programmable method that can be monitored from one central location. An alarm in the main room will let him believe that there is a problem, even if the heat shuts off at a building across town. He can then run tests from his location and seldom had to travel to the actual site. He can adjust the temperature in each location from there too. He simply has to reprogram the ipad to change the settings.. These type of automated systems work good for the most part. He must spend hours tracing it down when they do have a serious concern, sporadically by individual circuits, to find the concern and fix it. He gets frustrated at times, but typically solves the concern in the end. He does depend on the comprehension of local Heating and AC dealers too at times and they are truly helpful. When the method was first designed, they contracted with them so there are no individual charges to utilize these services. Plus it is typically helpful to be in contact with the professionals that understand the method inside and out. My boyfriend is truly wonderful at his task and understands the electrical parts of the method but some of the programing can be taxing to figure out.
