KW - SD
with snap-on lid is installed on cooling ceilings, on cooling ⁄cold-water piping or on cooled surfaces and is designed to
prevent the formation of condensation.
It reliably detects formation of dew by means of its humidity and temperature sensor (no conductivity measurement) and, thanks to its measuring
method,
pro-dynamic cross convection
, yields an exact measurement result (with LED status indicator).
Dew point temperature is that temperature at which air reaches the state of saturation and water vapour starts to condensate. The KW condensation
control switch can be operated as a monitor on cooling ceilings or pipes so that the switching output is activated when dew builds up on the cooling
ceilings of the property to be monitored and e.g. a heating system is started, or other actuators are initiated.

FUNCTION
The relay output is triggered (contact 13 -11 closed)
if the
switchpoint (93 % r.H.)
is not reached
and opens (contact 12 -11 closed) in the event of a fault (power failure, condensation).
LED short pulses =
relay active → switchpoint not reached
ACTUAL humidity
< 93 % r.H. (no condensation)
LED long pulses =
relay inactive → switchpoint exceeded
ACTUAL humidity
> 93 % r.H. (condensation)
