Turning the domestic hot water adjustment knob to the symbol
activates the pre-heating function. Bring the domestic hot water
temperature adjustment knob back to the required position. This

Heating Temperature Control function (C.T.R.)
Turn the heating water temperature selector into sector highlighted with
white markers to activate the H.T.C. self-adjusting system: based on the
temperature set on the ambient thermostat and the time employed to
reach it, the boiler varies automatically the heating water temperature
reducing the operating time, allowing great operation comfort and
energy saving.
C.T.R. FUNCTION
Unblock function
To restore operation, turn the function selector to

4.3 Checks during and after commissioning
After commissioning, ensure that the START boiler runs the start-up
and subsequent shutdown procedure correctly using the:
- function selector
- calibration of the heating water temperature selector and DHW
temperature selector
- required room temperature (adjusting the room thermostat or timer).
Check operation in DHW mode by opening a hot water tap with the
function selector set to Summer mode and to Winter mode.
Check that the boiler stops completely when turning the main system
switch to "OFF".
Operate the appliance continuously for a few minutes by turning the
main switch to "ON", setting the function selector to Summer and
keeping the DHW utility tap on. The processing binders and residue
evaporate and the following can be checked:
- supply gas pressure
- combustion.
Supply gas pressure check
- Turn the main system switch to "OFF".
- Unscrew the case screws (A).
