1.
Take off the cover.
2.
Install the base. In case of wall mounting, fix the base to the wall with 2
Ø 4 mm screws and corresponding dowels based on the quality of the wall.
In case of installation on a mounting bracket, use a TS 35/7.5 bracket.
3. Make the electric connection.
4. Install the cover.
The control direction is set with jumper 1:
NO operation:
Jumper 1 = ON
NC operation:
Jumper 1 = OFF
The fixed follow-up time of 2 minutes of the pump or
the boiler can be increased by an additional 5, 10 or
15 minutes using jumper 2 and 3:
Only use a dry and solvent-free, soft cloth for cleaning.
• De-energise the complete installation.
•
Remove the wiring to all externally connected components.
•
Remove the base and dispose of it properly, if necessary.
WARNING! Electrical voltage! Danger to life!
• Always disconnect the base from the mains network and secure
against unintended activation before opening.
• Disconnect external voltages and secure against unintended activation.

For the connection of the voltage supply, the cable sections must be 1.5 mm² for 230 V. Depending on the voltage version of the base, it is possible to take L1 or
L and L2 or N, as well as the protective conductor, from the base. A temperature limiter/dew point sensor can be connected to the contact TB/%H in NC operation;
this contact cannot be used in NO operation. If no temperature limiter is connected, the connection TB/%H must be bridged (provided for at the factory). The bridge
must be removed as soon as a temperature limiter is connected. The temperature limiter must be a normally closed contact.
