Condensation sensor
Art. No. : BTS01
Operating instructions
1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled
persons.
Serious injuries, fire or property damage possible. Please read and follow manual fully.
Danger of electric shock. During installation and cable routing, comply with the
regulations and standards which apply for SELV circuits.
These instructions are an integral part of the product, and must remain with the end
customer.

3 Function
Intended use
- Detection of water condensation on coolant lines in residential or functional buildings
- Connection to KNX pushbutton interfaces or similar binary inputs
- Fitting on the coolant line
Condensation sensor function
The device monitors the electrical conductivity between the conductive coatings on the sensor
surface. If it is dampened with water, the device detects the change and signals it.

iThe sensor surface can be damaged if it comes into contact with aggressive media (e.g.
detergent solutions, scrubbing brines or acidic condensation from condensing boilers).
Check the sensor area (3) after every alarm. In case of significant damage from corrosion
replace the device.
Cleaning instructions
Contaminations on the outer surface of the sensor can affect sensor function.
Contaminations that have become wet can retain moisture, so reports can exist for a long time,
as long as the condensation persists.
4 Information for electrically skilled persons
4.1 Fitting and electrical connection
Selecting installation location
The installation location should be the position that is most likely to have condensation. That
can be the coldest spot within a pipeline circuit.
For proper function, the sensor surface (5) must be ventilated so that condensation can form on
it.
When fitted in the vicinity of mixer valves, place the device on the colder inflow.
Fitting the condensation sensor

(7) Cable tie
(8) Thermally conducting pad
oClean the outer surface of the pipe. Remove any existing remaining paint.
oRemove the protective film from the enclosed thermally conducting pad.
oPut the self-sticking thermally conducting pad in the recession for the thermally conducting
pad (4) and slightly press on.
The thermally conducting pad adheres to the recession on the bottom side of the device.
oPlace the bottom side of the device directly on the pipe that is to be monitored.
oFit the device to the pipe with the accompanying cable ties (7).
oLock the connection cable into position.
