Function
K33 - controlled circuit with constant value 20-50 °C
with 3-way mixing valve and bypass 0-50%
The flow temperature of the HeatBloC
®
is controlled
by the integrated mixing valve. Hot water from the
boiler and cold return water are mixed to obtain the
desired flow temperature. The HeatBloC
®
flow
temperature is adjusted with a mixing head and a flow
sensor.
The rate of premixing is adjusted at the mixing valve
bypass and a certain amount of cold return water is
mixed to the flow water. The three-way actuator can
work over the whole adjustment range (0-100%).
Example: Radiant floors or walls are operated
with a low temperature level and low temperature
differences, but high flow rates. It is therefore
sufficient to "inject" a small amount of hot water
into the warm return water.
Application ranges:
•
Consumer circuits with considerably lower flow
temperatures than the boiler flow temperature
•
Small heating circuits with low power output
and low requirements regarding the control
•
Can be used instead of the K34 if the
controller cannot operate another mixing
valve.
