For an optimum utilisation of the advantage offered by the circulation controller, do not turn on any hot-
water tap unless you do not want to wait for the hot water to come (e.g. if you just wish to briefly wash
your hands). To remind the users of this, the scope of supply also includes stickers.
Installation
Important ! Read and observe safety hints before starting the installation !
Selecting the temperature measuring positions
The appropriate selection of the installation position and correct attachment of the temperature
sensors is of decisive importance for the proper functioning of the device.
Identifying the appropriate pipes on the hot-water storage tank:
1)
All pipes directly connecting the hot-water storage tank to the heating and hot-water boiler or heating
circuit should not come up for closer consideration.
2)
Characteristic features of the flow pipe (riser):
- is usually not connected to the top side of the hot-water storage tank
- is not directly connected to the cold-water pipe
- is not fitted with a pump
- in most cases, a three-way mixer valve (thickened T-piece) is installed
3)
Characteristic features of the return pipe (circulation line):
- may be connected to the hot-water storage tank from the side or from the top
- has often a smaller cross-section than the flow pipe
- is fitted with the circulation pump
4)
To be on the safe side:
- feel the temperature on the pipes coming into question with the circulation pump running
- switch off circulation pump for about 30 min; do not withdraw hot water during this time (the two
pipes of the hot-water circuit will now slowly cool down).
