7.2.17.3Indirect return increase

Function Indirect return increase is realised by means of the mixed heating circuit valves in the heating circuits. It only works for systems without a bypass pump and without controlled flow mixing.

When this function is active, two values are calculated independently for regulating each mixed heating circuit. The first value is the control variable for the flow setpoint of the heating circuit; the second is the control variable for the return setpoint.

The control variable used for mixed heating circuit control (mixed heating circuit control variable) results from the superimposition of both values. In this the adjustment of the return temperature is treated with priority.

Indirect return control is only active with mixed heating circuits that are in heating operation as well. It does not affect a heating circuit in reduced operation.

To avoid excessive pulsing, we recommend enabling the connected consumers (heating and hot-water circuits) with staggered switch-on times.

This function does not affect direct heating circuits.

NOTE Indirect return control is only feasible for systems without bypass pumps and without controlled flow mixing.

7.3.1General heating circuit functions

7.3.1.1Heating curve

The prerequisite for a constant room temperature is the exact setting of the heating curve of the relevant heating circuit as well as a correct design of the heating system on the part of the heating technician according to the heat demand calculation.

If adjustments are necessary, they should be made in small steps at a distance of a few hours to assure that a steady condition is obtained.
