Operation
– continued –
Stand-by operation with the steam boiler disconnected
Use an external switch to enable the stand-by
mode of the conductivity control.
After switching off the burner of the steam boiler
you can deactivate the control of the continuous
and intermittent blowdown valves in order to avoid
loss of boiler water (stand-by operation).
After returning to normal operation the continuous
blowdown valve moves into the control position
and an intermittent blowdown pulse is given
(if activated).
Please take the wiring diagram of the
installation manual for the LRR 1-40 into
consideration.
