Function
K33MAX - constant value control circuit
with 3-way mixing valve and bypass 0-50%
The flow temperature of the heating circuit
is controlled by the integrated mixing valve.
Hot water from the boiler and cold return water
are mixed to obtain the desired constant flow
temperature of the heating circuit.
The thermal control valve is integrated in the
mixing valve and prevents the flow temperature
from rising above the maximum temperature set.
At the rotary knob of the mixing valve, the
maximum temperature can be set between
35 °C and 55 °C depending on the installation.
Application example: Radiant panel heating
systems operate on low temperature levels with
small temperature differences and high flow
rates. It is therefore sufficient to "inject" a small
amount of hot water into the "warm" return water.
Application range:
•
Consumer circuits with a considerably
lower flow temperature than the boiler
flow temperature
•
Small heating circuits with low output
and low control requirements
•
Can be used instead of the K32 if the
existing controller cannot actuate an
additional mixing valve.
