Good evening, every time the power goes out, the L4448 THERMOSTAT is positioned in program P1. We use it only in manual mode and therefore if we are not at home and there is a power failure, the boiler turns on and brings the temperature to 22 degrees as set to P1 as max temperature. Is there a battery inside? Thanks for your kind response. Carlo Mercogliano 335 410292

"Operating status of the output" What do you need this sometimes black dot on the thermostat?

Does the 4448 thermostat have an internal battery? It no longer holds the programs, the M button doesn't store and the heating goes on even if I set the temperature to 15 degrees

We have this thermostat of the BTicino L4448 practically 20 years. We have always used the P3 program. If I wanted to do it manually and turn the heating on and off from the thermostat, can't I do it? The manual programming only says that I can set the ideal temperature and that's it, but by doing so the heating does not risk staying on all the time. I have never been able to solve this doubt. Thank you. I await your reply.

it's very simple, go to the MAN program and set the temperature like 18 degrees, the boiler turns on and off when the room reaches 18 degrees, then to switch off put the temperature at 10 degrees and you have solved

With manual setting you can set the minimum temperature at which the thermostat activates the boiler and the maximum temperature which, once reached, turns the boiler off. Good day

I have 2 L4448 thermostats, one for the attic and one for the ground floor. The one in the attic works and has the output operating status with an "empty" circle, while downstairs it doesn't work and the circle is all black and the radiators don't turn on. How do I solve the pb? I can't live in the attic.

What is the dead zone of a thermostat? Verified

Many modern thermostats have a dead zone. If the temperature deviates less than 4°C from the set temperature, the system will not heat or cool. This so called dead zone of the thermostat prevents the system from turning on and off too often, saving energy.

What is the best place to mount a thermostat? Verified

The best place for a thermostat is approximately 1,5 meter above the ground. Never place the thermostat nead a radiator or other heat emitting equipment or in direct sunlight. Choose a room that is used often. In most cases this is the living room.
