Winter-Water Heating Mode
The stove operates controlling both thermostats, but in this case the priority input (ING1) works in
the opposite way to the situations described previously. When both thermostats are satisfied, the
stove shuts down after a delay of 15 minutes.
Status of input ING1:
• Closed contact satisfied (t1 on display D2 is flashing)
• Open contact to be satisfied (accompanied by the message SANITARY on display D1:
in this case, the pump turns continuously, ignoring the minimum water temperature
threshold)
Status of input ING2:
• Closed contact to be satisfied
• Open contact satisfied (t2 on display D2 flashing)

9.1 External thermostat operation in STBY/TOFF mode (to be used also for
remote actuator)
The Standby function is used for further reducing fuel consumption, switching off the stove when
the desired temperature is reached.
1. Connect an external thermostat to contacts 1 and 2 of the board.
2. When the mechanical thermostat reaches the desired temperature, the stove goes into
“STBY-TOFF” phase, automatically switching off (external contact closed) without any
delay.
3. When the external contact opens again, the stove will switch back on in automatic mode.
N.B. If the user wishes to use this function, it is necessary to leave the jumpers in the
rear part of the stove connected in inputs ING1 and ING2.
