Grounding
Unscrew the control panel cover to have access to the connection terminals in the interior.
Connect the main electrical supply to the terminals 1, 2, 3 as indicated. The burner is
connected to the terminals 9, 10, 11 and the pump to the terminals 4, 5, 6. Connect the
burner command of stage 1 and of stage 2 to the terminals 12,13 and 14,15 respectively.
Between the terminals 7, 8 there is a jumper. If you want to connect a room thermostat,
remove the jumper and connect it to these two terminals.
Attention: The room thermostat must be a simple contact interrupter. It is not
allowed to connect a digital thermostat with an electrical signal output!
