Block that implements a room automation control function for sunblind control; from VDI 3813 [1].
Block calculated the setpoints for energy modes protection, economy, precomfort and comfort, heating and cooling respectively. Setpoint shifts may be induced from outside through the operator (T_BMS) or manually by the user (T_SETPT). Parameter of heating and cooling protection serve as boundaries and my not be crossed. Also a setpoint might not cross another setpoint, e.g. the setpoint for heating precomfort may not be larger than the setpoint from heating comfort. Setpoint shifts affect all setpoints equally. Setpoints comfort and precomfort are shiftable from the user and the operator. Setpoints for economy mode may be shifted only by the operator. Additionally setpoint for energy modes cooling comfort and precomfort may be shifted through the outdoor air temperature (T_OUT) termed "summer compensation".
