Z.3   Maintenance

In the course of the general annual maintenance of your heating system 

you should also have the functions of the controller checked by a speci-

alist and have the settings optimised if necessary.

Performing maintenance:

- Assess/check plausibility of analyses (see Chap. 6.11)

- Assess/check plausibility of analyses (see Chap. 2)

- Check the error log (see Chap. 2.4.)

- Verify/check plausibility of the current measurement values (see Chap. 1)

- Check the switch outputs/consumers in manual mode (see Chap. 3.2)

- Possibly optimise the parameter settings

   Caution
