KW-W-SD

HYGRASREG® KW-W-SD

Item No. 1202-1075-0001-020
EAN 4 251325 611662

Patented quality product (pro-dynamic cross convection patent no. DE 10 2012 015 726.6)

The condensation control switch HYGRASREG® KW with terminal box housing made of impact-resistant plastic and with an housing cover with quick-locking screws or the cost-effective HYGRASREG® 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.

Protection class III (according to EN 60 730)
Protection type IP 43 (according to EN 60 529)
Standards CE conformity,
electromagnetic compatibility according to EN 61326,
according to EMC Directive 2014/ 30/ EU
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)
