Heating Water Buffer Cylinder; Selecting The Operating Program - Viessmann VITOLIGNO 300-H Operating Instructions For The System User

Selecting the operating program

There are 3 operating programs availa-
ble for controlling the heating water tem-
peratures in the heating water buffer cyl-
inder:
■ "Automatic"
In automatic mode, the average set
temperature of the heating water buf-
fer cylinder is determined automati-
cally via the selected heating curve of
the heating water buffer cylinder. A set
value is determined subject to the out-
side temperature and the selected val-
ues for level and slope.
■ "Manual"
In manual mode, you can specify a
fixed value for the average set tem-
perature of the heating water buffer
cylinder. You can enter this set value
in the "Buffer" menu when manual
mode is selected.
■ "Off"
In this operating program, the heating
water buffer cylinder is heated by the
boiler. However, the heating water
temperature has no influence on the
boiler operation.
