CONTROL PANEL E-PILOT E-PILOT CONTROL PANEL The control panels fitted to ESSENCIO boiler incorporate an electronic control system used to adapt heating output to the actual needs of the installation according to the outside temperature (sensor provided). With ESSENCIO, it can be used to manage a single direct circuit, which may be a radiator circuit. With ESSENCIO, it can also be used to manage an additional circuit with a 3-way mixing valve by adding PCB MY440 available as accessory. The control can also be used to manage domestic hot water.
