MI 08 Set return

temperature

Conguration

km 01 = 7

The return temperature is permanently monitored. If the return

temperature falls too low, all mixers will be forced to raise the

return temperature.

Falling return temperature:

RL_ist < RL_Set + hysteresis, return temperature ⇒ all mixers

towards "CLOSE"

RL_ist < RL_Set ⇒ mixer towards "CLOSE" and all heating circuit

and cylinder primary pumps "OFF"

Rising return temperature:

RL_ist < RL_Set + 2 K ⇒ all mixers towards "CLOSE"

RL_ist < RL_Set + hysteresis, return temperature + 4 K ⇒ no

forced output

Hysteresis, return temperature = 8 K

MI 07 Mixer circuit

proportional range

Subject to application, the mixer circuit controller can be congured

for the mixer circuit in the heating ow or for the mixer circuit

for return temperature raising. The mixer circuit temperature is

regulated to the set value by means of the mixer circuit sensor /

return temperature sensor (mixer circuit in the heating ow / mixer

circuit for raising the return temperature) via terminal VF and a

motorised mixer. The output of the mixer controller for regulating

the mixer motor features P characteristics. The P range can be

adjusted for each parameter "Proportional range, mixer".

The impulse duration (= activation of mixer motor) is directly

proportional to the mixer ow deviation (∆T = Set - Actual).

Parameter

MI 07 determines the temperature deviation, for which

the pulse duration is 100%. Outside this range the mixer is either

not regulated at all (∆T < 1 K) or is regulated constantly (∆T > as

setting for par. MI 07) headed for. Within the temperature range,

the system exerts constant control. Adjust the proportional range

so that stable regulation is ensured. This depends on the runtime

of the mixer motor. For mixer motors with a short runtime, select

a wide proportional range and vice versa for mixer motors with

longer runtimes, select a narrower proportional range.

Setting information: These settings are only approximate

guidelines.

Change factory settings only where required.

MI 06 Mixer circuit pump

run-on time

switched OFF.
