15.1 MANAGING THE ELECTRIC HEATER
The units with Moducontrol offer the possibility to manage an electric heater; this heater can be managed in different ways:
— Supplementary (the simultaneous use of the heat pump and the electric heater);
— Anti-freeze or replacement (the heat pump compressor is switched off and the electric heater alone is activated);
The operational specifications of both modes are shown in the diagrams below.
The choice of supplementary or replacement mode depends on the external air temperature, and in case this falls below the
threshold indicated in the relative diagram.
