• Type of ON/OFF thermostatic control
1) on motor = poles 1 to ON and 2 to ON
2) on one valve (2-tube installations) = poles 1 to OFF and 2 to ON
3) on two valves (4-tube installations) = poles 1 to OFF and 2 to OFF
4) temperature control on the walves and the motor = pole 9 to ON
temperature control on the walves and the continuous motor speed = pole 9 to OFF
• MWT minimum temperature sensor
(positioned between the fins of the coil) prevents the motor operating with water temperatures of below 38°C
1) fitted = pole 3 to ON
2) not fitted = pole 3 to OFF
• Summer/winter switching
1) can be selected using the control unit keypad = pole 4 to ON
2) remote switching = pole 4 to OFF
3) automatic summer/winter switching with dead zone for 2-valve installations only poles 1 to OFF , 2 to OFF , 4 to OFF and 6 to ON
• Complementary electrical resistor
1) if it's present, pole n° 10 to ON
2) complementary electrical resistor mounted = pole 5 to OFF
• Selecting IN2 remote input
1) if wired = pole 7 to ON
2) supplying voltage to input IN2 varies the night time set point ( -3°C in winter and +3°C in summer) = pole 8 to ON
3) supplying voltage to input IN2 turns the instrument off and thus shuts the fan coil down - pole 8 to OFF
