Malfunctions and Maintenance

If the mains voltage is switched on and the controller still does not function or display anything, then the internal device fuse 
may be defective. In that case, open the device as described under C, remove the old fuse and check it. Exchange the defecti-
ve fuse for a new one, locate the external source of the error (e.g. pump) and exchange it. Then 

fi

 rst recommission the control-

ler and check the function of the switch outputs in manual mode as described under  „3.2. - Manual“ on page 14

Danger

Danger

Repairs and maintenance may only be performed by a specialist. Before working on the unit, switch off the 
power supply and secure it against being switched on again! Check for the absence of power!

Only use the supplied spare fuses or fuses of the same design with the following speci

fi

 cations: T2A / 250V .

Z.2   Replacing the fuse

Z.2.1  

Performing maintenance:
- Check the date and time

 (see „6.24. - Time and date“ on page 34)

- Assess/check plausibility of analyses

 (see „2. - Statistics“ on page 13)

- Check the error memory

 (see „2.4. - Message log“ on page 13)

- Verify/check plausibility of the current measurement values

 (see „1. - Measurement values“ on page 13)

- Check the switch outputs/consumers in manual mode

 (see „3.2. - Manual“ on page 14)

- Possibly optimise the parameter settings

Z.3   Maintenance

Caution

In the course of the general annual maintenance of your heating system you should also have the func-
tions of the controller checked by a specialist and have the settings optimised if necessary.
