1.
Determine the optimum bypass position during commissioning in a trial-and-error
process.
When the slot of the bypass screw
is in a vertical position, the bypass
is closed (normal operation).
When the slot of the bypass screw
is in a horizontal position, the
bypass is completely open.
This allows the highest possible flow
rate from the return to the flow line.
This adjustment may be necessary
for radiant floors requiring a very
high flow rate. The flow temperature
is low and the control may be
negatively affected.
2.
Check the bypass position during operation. Make sure that the flow rate is sufficient
and that the desired temperature is reached.
