Our equipment does not include batteries, so replacing them is not needed. The power is supplied to them as follows:
A. Equipment in electrical center get their supply from there.
B. Temperature sensors need a small amount of power to transmit the measurement value with WiFi technology. We have manufactured sensors with batteries, but our customers have not been happy with changing batteries. Today our sensors are simply connected to a normal wall 220 V power outlet.
Do I have to change batteries to the equipment?
