1. Pressing the
key decreases the temperature.
2. Pressing the key increases the temperature.
3. The temperature adjustment field of the domestic hot water
ranges from a minimum of 35 °C to a maximum of 60 °C.
6.3.7 OFF mode
In this operating mode the boiler no longer provides heating
and DHW, but the antifreeze and pump anti-lock systems remain
active.
To switch the boiler to the OFF operating mode, press the
key; the fixed symbol will appear on the display, indi-
cating that the function has been activated.
If the boiler was previously in operation, it is switched off and

If you decide to shut down the boiler for a long period of time,
secure it by operating in one of the following two ways:
1. Call the TAC that will empty the water system, where there
is no provision for the use of antifreeze, and disconnect the
power supply, water and gas.
2. Leave the boiler in the OFF operating mode, keeping the
power and gas supply active, so that the antifreeze function
and the pump anti-lock function can be activated.

7 MAINTENANCE
Correct maintenance prevents problems, assures effi-
ciency and keeps running costs low.
Maintenance operations described herein may exclu-
sively be performed by the TAC or skilled maintenance
technician.
Any operation on internal components may exclusively

carried out each year:
▶
Combustion circuit functionality and heat exchange control:
„ Burner and flue exhaust duct inspection
„
Cleaning of burner and water/flue exchanger (if applica-
ble)
„
Flame ignition/detection system control
▶
Hydraulic circuit and internal components functionality
check:
„
