Functional description
Only visible if Control type = External opt. (Optimized outdoor
reset control) is selected:
This is the supply temperature requested at the outdoor design
temperature (see setting Min.outs.temp). The control range
depends on the heating system selected.
Only visible if Control type = External simple (simple outdoor
reset control) is selected:
This is the supply temperature at fixed outside temperature of
68 °F (20 °C). The range is limited by the setting of the End
point.
Only visible if Control type = External simple (simple outdoor
reset control) is selected:
This is the supply temperature requested at the outdoor design
temperature (see setting Min.outs.temp). The range is limited
by the setting of the Base point.
Maximum supply temperature; the control range depends on
the heating system selected.
Control characteristics (only visible when room temperature-
dependent control is selected):
Fast: Fast (2k P range), older home, loose construction, limited
insulation
Medium: Average (3k P range), Minimum building
requirements, medium construction
Slow: Slow (4k P range), newer home, tight construction, well
insulated
YES: Optimized pump operation active: The heating pump runs
as little as possible on the basis of the supply temperature
(available only with supply temperature control). This saves
energy but may also reduce comfort.
NO: If the system has more than one heat source installed (e. g.
a hybrid system) or a buffer storage tank is installed, this
function must be deactivated.
