- switch on circulation pump again; now, first the flow pipe and then the return pipe will heat up.
Selecting the measuring position in the flow pipe:
If the sensor is fitted closer to the hot-water storage tank, the water quantity required for activating the
circulation pump will be smaller. However, the temperature changes in the storage tank itself will also
have a greater impact. In particular with continuous copper pipes, it is advisable to position the sensor at a
sufficiently large distance from the tank. If there is a mixer valve in the circuit, install the flow sensor
between the valve and the storage tank. Practical experience has shown that distances to the storage tank
of about 20 to 40 cm are appropriate. With copper pipes, a somewhat greater distance, and with plastic
pipes, a somewhat smaller distance should be chosen.
For systems including different materials, the following applies: Prefer metal to plastics and thin-walled to
thick-walled parts for fitting the sensors.(Further useful hints can be found at www.dr-clauss.de/circon).
The measuring point in the return pipe is not critical, but it should be located as far away as possible from
the hot-water storage tank.
Important:
If you have changed the locations at which the sensors have been mounted, you have to
newly start CIRCON. (Pull device out of socket outlet for a few seconds.)
Attaching and connecting the temperature sensors
Fasten sensors by means of adhesive fabric tape (included in scope of supply) longitudinally relative to the
pipe so that the silicone sheath is uniformly pressed over its entire length with its concave contact surface
onto the surface of the pipe. Make sure that no adhesive tape or other foreign matter comes to be placed
between the sheath and the pipe and that the ends of the sensors are not bent.
