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

The condensation control switch HYGRASREG® KW with housing made from impact- resistant plastic 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.

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)

General notes

• This device must only be used in non-precipitating air without above-atmospheric or below-atmospheric pressure at the sensor element.
• On outdoor and duct sensors, the sinter filter of the senor element protects the humidity sensor against potential dust exposure. In case of pollution/contamination, this filter should be cleaned on a regular basis.
• Dust and pollution falsify measurement results and are to be avoided. Slight pollution and dust sediments can be removed by using compressed air.
• Touching the humidity element is under any circumstances to be avoided, as that would result in considerable mismeasurements.
• In case of pollution, we recommend cleaning and recalibration in the
• In any case, the sensor must not get in contact with chemicals or other cleaning agents.
• The relative humidity of 0…100% is indicated by an output signal of 0 -10 V or 4 … 20
• The device operating range covers0…99.9% r. I-I. Beyond that range, mismeasurements or increased deviations may occur.
• When several sensors (0.10 V) are connected to one voltage supply of 24V AC, correct polarity must be regarded as otherwise the alternating voltage source may be short-circuited.
• The voltage outputs are short-circuit proof. Applying overvoltage or voltage supply to the voltage output will destroy the device.
• If this device is operated beyond the specified range, all warranty claims are

Our “General Terms and Conditions for Business” together with the “General Conditions for the Supply of Products and Services of the Electrical and Electronics Industry” (ZVEI conditions) including supplementary clause “Extended Retention of Title” apply as the exclusive terms and conditions.

Notes on commissioning: This device was calibrated, adjusted and tested under standardised conditions. When operating under deviating conditions, we recommend performing an initial manual adjustment on-site during commissioning and subsequently at regular intervals.

Commissioning is mandatory and may only be performed by qualified personnel!
These instructions must be read before installation and commissioning and all notes provided therein are to be regarded!

SUPPLY VOLTAGE:
For operating voltage reverse polarity protection, a one-way rectifier or reverse polarity protection diode is integrated in this device variant. This internal one-way rectifier also allows operating 0 -10 V devices on AC supply voltage.
The output signal is to be tapped by a measuring instrument. Output volt­age is measured against zero potential (0 V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage input UB+ is to be used for 15…36 V DC supply and UB— or GND for ground wire!
When several devices are supplied by one 24V AC voltage supply, it is to be ensured that all ‘positive operating voltage input terminals (+) of the field devices are connected with each other and all ‘negative operating voltage input terminals (—) f= reference potential) are connected together fin-phase connection of field devices). All outputs of field devices must be referenced to the same potential!
In case of reversed polarity at one field device, a supply voltage short- circuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
