10 Energy saving tips
With outdoor reset controls, the supply
•
temperature is controlled in accordance with
the set heating curve: The colder the outdoor
temperature the higher the supply
temperature.
Save energy: Set the heating curve as low as
possible in accordance with the building's
insulation and the system conditions
( section 8.3 from page 67).
Radiant floor heating:
•
Do not set the supply temperature higher than
the maximum supply temperature
recommended by the manufacturer (e.g.
140 °F (60 °C)).
Make effective use of the temperature levels
•
and switch points by setting them to suit the
preferences of the occupants.
– Comfort = Comfortable living
environment
– Economy = Active living environment
– Frost = Away from home or asleep.
Set the thermostat valves in all rooms so that
•
the required room temperatures can be
achieved. Only increase the temperature
levels if the temperature has not reached after
some time ( section 6.2.2 on page 41).
Much energy can be saved by reducing the
•
room temperature via economy phases:
Reducing the room temperature by 1.8 °F
(1 °C): up to 5% energy can be saved.
Not recommended: To let the room
temperature fall below 60 °F (+15 °C) during
the daytime, otherwise the cooler walls
continue to radiate cold, the boiler works
harder to raise the rooms to the desired
temperature, leading to higher energy
consumption than if a constant heat supply
had been applied.
With well insulated buildings it can be the
•
case that the room temperature remains
6 720 643 256 (2010/05)
above the temperature set for Economy.
Nevertheless energy is being saved as the
heating system stays off. In this case, you can
set the switch point for Economy earlier.
Don't keep windows cracked for ventilation.
•
This way, heat is always drawn out of the room
without noticeably improving the room air.
Vent briefly but intensively (open window
•
fully).
When ventilating, turn off the thermostatic
•
valve or set the mode selector to Frost.
Make effective use of the temperature levels
•
and switch points for the hot water by setting
them to suit the preferences of the occupants.
Solar optimization
Activate the DHW optimization by setting a value
between 1.8 °F to 36 °F (1 °C to 20 °C)
( section 6.5 on page 50).
If the influence of the DHW optimization is too
great, reduce the setting a small amount at a
time.
Activate the Heating circuit optimization by
setting a value between 1.8 °F to 9 °F (1 °C to
5 °C) ( section 6.5 on page 50).
If the influence of the Heating circuit
optimization is too great, reduce the setting a
small amount at a time.
