In calculating the lengths of the pipes, the
maximum length “L” must also take into
consideration the values for the exhaust/air
intake end terminals, as well as 90° elbows for
coaxial systems.
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.
Note: A frost thermostat is built-in to the appliance.
For connection to control systems with zone valves
for hot water cylinders see section 3.
