Menu Setting House Parameters
(
Installer/Settings/Setting house paramt
)
The house’s heating requirement (the heating curve) is set in this menu. It is
important that this basic setting is correct for your house. Incorrectly set values
can result in insufficient heating, or that unnecessarily high levels of energy are
used to heat your house. Particularly great emphasis should be focussed on
determining the “Inclination” and “Adjustment” values.
Max Prim fl.°C
55
Maximum permitted temperature of the water supplied to the radiators. This
functions as an “electronic” lock to protect floor circuits in floor heating
systems.
Min Prim fl.°C
Off
Adjustable from15–65. If, in the summer months, you want cellar or floor circuits
(e.g. bathrooms) to have a specific level of background heating, a minimum
permitted temperature can be set here. Other sections of the house should be
shut off using thermostat valves or shut off valves.
Heating off°C
16
Outdoor temperature at which the house no longer requires heating.
The radiator pump stops and the mixing valve valve remains closed. The
radiator pump is exercised daily for a short period so that it does not jam. The
system starts automatically when heating is required.
Heating curve
Collective name for the house’s heating curve. The house graph consists of an
“
inclination
” and an “
adjustment
”, which together define the temperature the
house requires at different outdoor temperatures.
Inclination
°C
50
This value is the temperature of the water supplied to the radiators at an out-
door
temperature of –15°C. A lower value is set for radiator systems with larger
radiator surface areas (a low temperature system).
Floor heating systems
require
much lower temperatures. An even lower value should therefore be selected.
The value is increased for high temperature systems, so that sufficient indoor
temperatures are achieved.
High temperature systems
are not optimised for heat
pump operation and savings will therefore be lower.
Adjustment
°C
The
inclination
defines how much the temperature of the water supplied to the
radiators should be increased where outdoor temperatures fall. The
adjustment
specifies that the temperature level can be raised or be lowered at a specific
outdoor temperature.
Example:
Inclination 50 specifies that the temperature of the water supplied to
the radiators is 50°C when the outdoor temperature is –15°C,
if the adjustment
is set to 0
. If the adjustment is set to +5, the temperature is 55°C. The graph is
increased by 5°C at all outdoor temperatures, i.e. the graph is parallel displaced
by 5°C.
