The Aestiva S2011-2 controller comes with Smart Heat Management (SHM) mode. The SHM reduces overheating/stagnation
During the summer, the solar storage tank can reach top out temperatures during the day causing the collectors to enter stagnation condition, generating steam and unnecessary stress to the solar system. This can result in thermal shock which produces a loud hammering noise from the tank. When the SHM mode is activated, the Aestiva controller detects this condition and activates reverse differential solar control during night time to cool down the bottom half of the tank. The bottom tank water will start cooling in 2nd day and prevents stagnation from occurring. The top half tank is unaffected, as the circulation only happens at the lower half of the tank, so hot water usage during the morning is no issue. The SHM mode can be set using Program Mode by the end-user. This is handy during the holiday season, when you may be away from home for an extended period of time.
