"Heating water buffer cyl."
Set temperature of heating water buffer cylinder (20
to 90 °C)
Note
If the set temperature has been specified by a higher
ranking system, the field only functions as a display.
■
"Maintaining set val"
Set temperature for high temperature maintenance
(20 to 90 °C)
The input range is determined by the application lim-
its.
Note
The lower the set value for high temperature mainte-
nance, the better the COP
Note
If the set temperature has been specified by a higher
ranking system, the field only functions as a display.

"Htg limit"
If the average outside temperature (averaging over
24 hours) is lower than this value, the heating func-
tion for the heating water buffer cylinder is enabled.

The achievable flow temperature in the secondary cir-
cuit is dependent on the temperature of the heat
source.
Example:
If the flow temperature in the primary circuit is 0 °C, the
maximum flow temperature in the secondary circuit is
73 °C.
