Description of work:
The regulation reads on the upper sensor accumulation tank temperature, minimum accumulation tank
temperature and accumulation tank difference. At the bottom sensor, regulation reads the accumulation tank

works until the temperature on the lower sensor (T accumulation tank - T accumulation tank shutdown
difference) is reached. The boiler will turn ON again when accumulation tank upper temperature (upper
sensor) reach the (T accumulation tank - T accumulation tank difference).
