Load control

The heat output of mixing valve control can be reduced by functions of higher priority
(e.g. by return temperature limitation) or by functions of other plants (boiler, DHW
heating). This is accomplished via load control.

Load reduction can be triggered by one of the following functions:
• Protective boiler startup
• Limitation of the return temperature
• DHW heating with shifting priority
• DHW heating with absolute priority
From the consumer's point of view, a load increase can be effected in the form of pump
and / or mixing valve overrun. In principle, this means load maintenance.
