All Thermal Technology heating system can be controlled by an ambient sensor that controls the heating element directly through a relay. The PCU has a program that constantly analyzes the actual consumption of electricity and, on the basis of the usage rate of the whole heating system, limits the total power intake and does not allow the exceeding of the limits set by the electric meter.
This translates in lower operational costs. The PCU can control up to 14 zones and is connected to the thermostat or temperature sensor which regulates each single zone (it is advisable the use of one thermostat or temperature sensor for each room) and modulates the on/off of the heating elements. In addition, some zones can be used to operate and control other appliances (washer, dishwasher, oven etc.) to monitor and disconnect in case of overload. PCU replaced the CU if present in the radiant panel which would then be supplied with an ON/OFF switch.
