3 Tips on economical heating

Here are a few tips on how to heat economically, without sacrificing

comfort, using your RC30:

z Only heat if you need warmth. Use the heating programs preset

in the RC30 or those which you have tailored to your personal

needs.

z Ventilate correctly during the cold season: Open the windows

wide three to four times per day for approx. five minutes.

Having the window slightly open all the time does not provide

fresh air changes and wastes valuable energy.

z Close the thermostatic radiator valves when the room is being

ventilated.

z Windows and doors are places where a lot of heat is lost. So

check that the doors and windows are correctly sealed. At

night, close your shutters and blinds (if installed).

z Heat in an energy-conscious manner during in spring and

autumn, and make use of the summer/winter changeover

function (see Chapter 9.10 "Setting summer/winter

changeover", page 72). In summer mode the heating is

switched off and only DHW is heated. In winter mode the

heating and DHW are activated.

z Never position large objects such as a sofa or a desk

immediately in front of the radiators (maintain a clearance of at

least 50 cm). Otherwise the heated air cannot circulate and

heat the room adequately.

z In those rooms which you occupy during the day, you can set

a room temperature of 21 °C, for example, whilst 17 °C may be

sufficient at night. You can do this using day and night modes

(see Chapter 7 "Basic functions", page 20).

z Never overheat rooms. Overheated rooms are unhealthy and

cost energy and money. If you reduce the daytime room

temperature, from 21 °C to 20 °C, for example, you will save

around six percent on your heating bill.
