4 Electrical accessories Electric heater batteries The heater battery operation must be enslaving to the fan operation. The installation must include a switch to switch off the electric heater battery supplies in case of fan failure. E-SCT Electric heater batteries with built-in electronic temperature control. - uto-resetting thermal protector 55ºC. - Manual resetting thermal protector 7ºC. - uilt-in electronic temperature control. - Conduit temperature probe and potentiometer. - Pressure switch (optional). Electronic control Electronic control E Electric heater batteries Functions: - Defrosting operation: To heat the outside fresh air before going through the heat recovery unit to avoid frost accumulation ans sealing of the heat exchanger. - Post heating operation: To increase the temperature of the supply air, after the heat exchanger.
