3.7 When the thermostat is functioning normally, a faint click is heard when the load is
switched on and off.
3.8 Ventilation mode: when thermostat notices a major decreasing in room
temperature (room is being ventilated) the load is automatically connected off for 15
minutes. After this the functioning of the thermostat becomes normal.
3.9 Self diagnostics: when the fl oor sensor is used the thermostat recognizes if the
sensor is short-circuited, cut off or missing. The fault is indicated by blinking the red
(B) and blue (C) signal lights in turn.
