Special mixing circuit functions (district heating control devices only)

Return limit By setting an additional return sensor in the mixed heating circuit, the return temperature can be limited using this function. This is a maximum temperature limit.

With some applications, an excessively high return temperature causes problems (e.g. district heating or condensing applications). They can occur if heat is not being extracted in the occupied room (e.g. thermostat valve closed).

If the return temperature exceeds the set maximum value, the mixed heating circuit valve is adjusted to this maximum temperature. The flow temperature then remains ignored.

7.3.4.10.1.1Proportional part Xp

The proportional band Xp defines how a step change of the setpoint effects a change of the corresponding actuator according to the selected setting.

Example:

Consider an actuator moving though an angle of 90°C in an action time of two minutes. When a sudden flow temperature control deviation of 10 K occurs (e.g. when the system switches from reduced to daytime operation) and the P-part setting is 5%/K, the actuator has to open by 50% (5%/K x 10 K). Consequently, the duration of the actuation pulse is one minute (= 50% of the actuator runtime).
