Heating Division DIVATECH D SOLAR CIRCUIT INTEGRATION DIVATECH D boasts an electronic that simplifies the integration with thermal solar sytems, both natural and forced circulation. The microprocessor monitors water temperature coming from solar circuit through the DHW sensor and ignites the burner only in case it is necessary. In such a case the boiler releases only the necessary heat to DHW which had already pre-heated by collectors, in order to reach the setpoint required by the user, allowing at the same time considerable savings even during cooler seasons. FUNCTION M FUNCTIONS ANTIFREEZE Also in standby-mode, in case the temperature in the boiler drops to 5 C (temperature detected by CH or DHW sensor), the burner is automatically ignited at the minimum output and pump is also switched on. Thereby the appliance is protected against damages caused by frost. This function is active when the boiler is gas and power supplied. ANTI-BLOCK FUNCTION Pump is automatically switched on approximately for 5 seconds, after 24 hours of inactivity. This protection schedule is applied also for diverting valve. Such precaution avoids block of the mentioned devices in case of long inactivity. POST-CIRCULATION This function permits to recover all heat stocked for thermal intertia in the central heating exchanger and transfer it to the heating system, and as a consequence to the rooms. It is a timed function (with customisable span) and is active after burner switches off in heating mode. EVOLVED COMBUSTION SYSTEM Innovative combustion control which ensures the best operation at the different conditions of thermal load and draught ( F forced flue model). The combustion set has been carefully designed as a synergic group, in order the components interact together, under the supervision of the control board. 5
