HYGRASREG TW
Patented quality product (pro-dynamic cross convection patent no. DE 10 2012 015 726.6)
The dew point control switch HYGRASREG
by means of its humidity and temperature sensor (no conductivity measurement) and, thanks to its patented measuring method, pro-dynamic cross
convection, yields an exact measurement result (with LED status display), with ⁄ without display. Dew point temperature is that temperature at
which air reaches the state of saturation and water vapour starts to condensate. Facilitated by the continuous measuring range from 0...100 % r.H.
of the TW-U and the adjustable switchpoint for the TW-W of 75...100 % r.H., it is possible to operate cooling ceilings, for example, so that the
switching output of the dew point control switch, the DDC, is activated and then triggers a heater or other control elements, thereby preventing the
formation of dew on pipes or cooling ceilings or on the property to be monitored.

IP 65 (according to EN 60 529) Housing tested, TÜV SÜD, Report No. 713139052 (Tyr 1)
CE conformity, electromagnetic compatibility according to EN 61 326, EMC directive 2014 ⁄ 30 ⁄ EU
two-line display with illumination, cutout approx. 36 x15 mm (W x H),
for displaying actual humidity and the switching status of the relay
The relay output is triggered (contact 13 -11 closed)
if the pre-set switchpoint (factory setting 75 % r.H.)
is not reached and opens (contact 12 -11 closed) in the event of an error (power failure, condensation).
LED short pulses =
relay active → switchpoint not reached
ACTUAL humidity < pre-set switchpoint (no condensation)
LED long pulses =
relay inactive → switchpoint exceeded
ACTUAL humidity > pre-set switchpoint (condensation)
