Changeover of operating mode
• Heating circuits
The operating mode of the respective heating circuit(s) is switched to Protection via
terminal Hx (e.g. by means of a remote telephone switch).
• DHW
DHW heating is locked only when using setting 1 (HCs+DHW) All temperature
requests made by the heating circuits and by DHW are ignored. Frost protection is
maintained.
Error / alarm message
When input H1 closes, a controller-internal error message is triggered.
If the alarm output (relay outputs QX1 – QX6, 5890 – 5896) is appropriately configured,
the error is forwarded or indicated by closing an additional contact (by an external lamp
or horn).
