two cables with control signal (see the figure).
When the electric heater is used together with a DUPLEXVENT unit with built-in control, this control ensures that all
conditions for the safe operation of the heater are met.
When the electric heater is used together with a DUPLEXVENT unit without built-in control, its operation is allowed only
