INP1. When input INP2 must be satis ed the display shows DHW.
only when both thermostats are satis ed, the boiler switches o after a 15 minute delay showing “TOFF”
on the display.

Electrical features applicable external devices:
Max. voltage: 230 V
Frequency: 50 Hz
Max. power per channel: 250 W
SAFETY ZONE
This function activates if the water temperature inside the boiler exceeds 85°C: even if there is no
request for heat, the electro-thermal pump/control relating to OUT4 and OUT3 is enabled.
The stopping of the electro-thermal pump/controls will happen when the temperature decreases.
It is fundamental that the installer foresees the presence of an important heating area in the
home, in which at least one radiator is never closed.
The lack of a venting area can lead to boiler overheating with consequent activation of the
mechanical safety devices. The outputs performed by the Extra ame after-sales service in order to
release these safety devices are under the customer’s responsibility.
