For mounting, a protection pocket is provided; the controller is inserted and snaps on.
The controller is supplied complete with Mounting and Installation Instructions.
Ensure that the local safety regulations are complied with.
Suitable mounting locations are the following, depending on the application:
• Flow temperature control:
In the heating flow; immediately after the pump if the pump is mounted in the flow
−
In the heating flow; approximately 1.5 to 2 m after the mixing point if the pump is
−
mounted in the return
• Minimum limitation of the boiler return temperature and maximum limitation of the
flow temperature:
1.5 to 2 m after the mixing point
• DHW temperature control:
1.5 to 2 m after the mixing point
• Heat exchanger control:
As close as possible to the heat exchanger while observing the maximum
permissible ambient temperature
To mount the protection pocket, a threaded sleeve must be fitted into the pipe. The
immersion rod should face the direction of flow. The maximum permissible ambient
temperature must be observed.
Warning!
No internal line protection for supply lines to external consumers.
Risk of fire and injury due to short-circuits!
• Adapt the line diameters as per local regulations to the rated value of the installed
overcurrent protection device.
• The AC 230 V mains supply line must have an external circuit breaker with a rated
current of no more than 10 A.
To check the control wiring, the controller can be switched into test mode so that the
response of the actuating device can be checked.
In case of instability of the control loop, the P-band is to be increased, and/or the
integral action time selection. If the response of the system is too slow, these values
are to be reduced.
The devices are considered electronics devices for disposal in terms of European
Directive 2012/19/EU and may not be disposed of as domestic waste.
• Dispose of the device via the channels provided for this purpose.
• Comply with all local and currently applicable laws and regulations.
