Return control If the actual return temperature falls below the set return tem perature then the mixer bypass is opened further by switching the mixer enabling a greater amount of heating water to flow through the mixer bypass If the actual return temperature rises above the set return temperature then the mixer bypass is closed further by switch ing the mixer restricting the amount of heating water to flow through the mixer bypass Indirect return temperature raising with configuration MOS 7 Configuration 7 includes an indirect return temperature raising to regulate the mixer circuit The indirect return temperature raising is always active when at least one heating or cylinder circuit is active When the actual return temperature drops with indirect return temperature raising the actual return temperature is forced higher for all heating and cylinder circuits through enforcing a higher output This forced higher output has two stages At stage 1 all system mixers are switched to move towards Close and in addition in stage 2 all heating and primary pumps at stage 1 are switched off Falling return temperature RL act lt RL set hysteresis return temperature mixer towards CLOSE RL act lt RL set gt mixer towards CLOSE and all heating circuit pumps OFF Rising return temperature RL act gt RL set t 2 K mixer towards CLOSE RL act lt RL set hysteresis return temperature 4 K no forced actuat
