These setpoints become active depending on the selected operating mode, thus producing different temperature levels in the rooms.
Heating curve displacement Heating curve adaption Parallel displacement of the heating curve is used to change the flow temperature evenly across the entire outside temperature range or, in other words, if the room temperature is always too high or too low, a readjustment must be made with the help of the parallel displacement. Adaptation of the heating curve is used by the controller to automatically adapt the heating curve to the prevailing conditions.

Operating line 908 909 Flow setpoint at outside temperature of 25°C Flow setpoint at outside temperature of 35°C The controller determines the required flow temperature at a specific composite outside temperature. The cooling curve is determined by defining two fixed points (the flow temperature setpoint at 25°C and 35°C). The programmed cooling curve is based on a room setpoint of 25°C.
Start of summer compensation at OT Summer compensation starts to take effect at the outside temperature set here. If the outside temperature continues to rise, the comfort setpoint is raised in parallel. End of summer compensation at OT Summer compensation takes full effect at this outside temperature (920). The comfort setpoint is not affected by any further increase in the outdoor temperature.

Excess heat draw Excess heat draw can be triggered by the following functions: − Inputs H1, H2, H3 or EX2 − Storage tank recooling − Solid fuel boiler excess heat draw When dissipation of excess heat is activated, it can be drawn by space heating. This can be adjusted separately for each heating circuit. With buffer storage tank If there is a buffer storage tank, this defines whether the H1/H2/H3 circuit can draw heat from it.
If the swimming pool is enabled via one Hx input, the swimming pool priority is equivalent to the parameter setting. Solar heating must now be enabled via the Hx input. If two Hx inputs are used to enable the swimming pool, the swimming pool takes priority when both Hx inputs are enabled. If only one Hx input is enabled, the swimming pool priority is determined by the parameter setting. If none of the Hx inputs are enabled, solar heating of the swimming pool is deactivated. Plant hydraulics Line no.
In normal operation, minimum limitation of the boiler temperature is the lower limit value of the controlled boiler temperature setpoint, depending on the boiler’s operating mode. In normal operation, maximum limitation of the boiler temperature is the upper limit value of the controlled boiler temperature setpoint and, at the same time, setpoint of the electronic limit thermostat (TR).

Also, the actuator running time is to be set. • Neutral zone For control operation, a neutral zone is used which is at +/- 1K about the current boiler temperature setpoint.
2 x 1 cascade The 2x1 cascade is a special configuration of the basic unit, where the 2-stage boiler is operated as 2 cascaded 1-stage boilers. T 2 QX4 B2 1 T2 QX2 (Q1) QX1 (Q1) Due to the temperature differential between boiler temperature setpoint and boiler temperature sensor B2 (common, mandatory cascade flow temperature sensor), switching on / off of the lag boiler (release and reset integral) takes place according to the control of a 2-stage burner.

Bypass pump Q12 The connected pump serves as a boiler bypass pump for maintaining the boiler return temperature.
Heat gen shutoff valve Y4 If the buffer storage tank holds a sufficient amount of heat, the consumers can draw their heat from it, and the heat sources need not be put into operation. Automatic heat generation lock locks the heat sources and hydraulically disconnects them from the rest of the plant with the help of heat source shutoff valve Y4. This means that the heat consumers draw their energy from the buffer storage tank and wrong circulation through the heat sources will be eliminated.
