Description

Condensation control switch HYGRASREG® KW
Patented quality product (pro-dynamic cross-convection, patent no. DE 10 2012 015 726.6)
The sensor device is installed on cooling ceilings, cooling or cold-water pipes and cooled surfaces, and has been designed to prevent the formation of condensation. It reliably detects the formation of dew by means of its humidity and temperature sensor (no conductivity measurement). Thanks to its measuring method of pro-dynamic cross-convection it yields precise measuring results (with LED status indicator). Dew point temperature is the temperature at which the 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 e.g. to start a heating system or initiate other actuators when dew builds up on the cooling ceilings of the property to be monitored.

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)
