2.10ROOM THERMOSTAT CONNECTION

To connect a room thermostat and/or time clock, it is necessary to:

1. - Open the control panel as indicated in section 4.3;

2.- Remove screws “A” and remove the inspection cover from the reverse of the control panel;

3.- For the room-thermostat connect the thermostat switching wires to the position 5 and 6 and remove the wire link (for three-wire thermostats connect the neutral to terminal N);

4.- For the time clock connect the clock switching wires to the positions 3 and 4 and connect the clock motor electrical supply to the terminals marked L and N.
