4.3 Room thermostat (optional)
The boiler/thermostove Ungaro has an inlet
for a room thermostat with a clean contact.
Once the room reaches the set temperatu-
re, the thermostat regulates the boiler on
minimal power, without switching off. The
automatic regulation is possible only if the
thermostove is on. If the appliance is
OFF
,
any comand from the room thermostat
cannot reach the stove.
Do not connect 220V-powered room
thermostats, they can damage mo-
therboard.
When set temperature reached, on display
D2
appears “
TOff
”.
How to wire a room thermostat:
• Turn off the boiler/thermostove main
switch;
• Remove the by-pass on the back of
the boiler/thermostove (fig. 14);
• Connect the wires following the ther-
mostat diagram.
