I installed the BES system for a month, I like it very much as it is so convenient to control by Apps and even you are away from home. Of course, it also saves energy through the easy control mode. The digital sensors also can display the exact temperature instead of the traditional I-V temperature level. It’s worthwhile to install this BES system from a environmental friendly perspective besides economical benefit. The remote support from the Vendor is also much appreciated. I highly recommend to other people.
