Basic Heating Technology Know-How

With the Vitotrol remote control the following adjustments can be made:

� “normal room temperature“

� “reduced room temperature“

� domestic hot water temperature

� operating and holiday mode

� heating cycles for space heating, domestic hot water production and the DHW

recirculation pump (if applicable)

� date and time

Except for “normal room temperature” adjustments, all adjustments are transferred

from the Vitotrol remote control to the Vitotronic control unit and vice versa.

Your latest adjustments are effective for your heating circuit.

For the adjustment of the domestic hot water temperature, your heating contractor

can alter codings accordingly - please contact your heating contractor.

The timer of the remote control will automatically switch between “normal room

temperature” and “reduced room temperature” at the preselected times.

1. Normal room temperature

for a comfortably warm living

environment (e.g. 68 ºF / 20 ºC).

2. Reduced room temperature

at nighttime or for the times you

spend away from home. To save

energy this room temperature is set

lower than the “normal room

temperature”.

At the time of delivery “frost

protection” is set to 37 ºF / 3 ºC.

You can select the time and duration of

the room temperature on your

programming unit.

The desired room temperature can be

selected for both “normal room

temperature” and for “reduced room

temperature”.

The timer of the remote control activates and deactivates domestic hot water

production at selected times (only for boiler with domestic hot water tank).

1. Domestic hot water production takes

place when you are at home and

require domestic hot water for your

everyday use (e.g. showering).

2. Domestic hot water production does

not take place

e.g. at nighttime

You can select the time and duration of

the room temperature on your

programming unit.

Desired temperature for domestic hot

water is adjustable up to 140 ºF / 60 ºC.

The domestic hot water recirculation

pump (if applicable) ensures short-term

availability of domestic hot water at

different draw-down locations.

heating cycle 1 is set for every day of the week from 06:00 to 22:00 hrs., which

means that during this time period space heating takes place according to the

selected “normal room temperature”.

The following options are available to you to set the heating cycles to your liking:

� By selecting the corresponding heating cycle, space heating can alternate up to

four times a day between “normal room temperature” and “reduced room

temperature”.

� You can select the same heating cycle or individual heating cycles for each day

of the week.

When setting the heating phases please pay attention to the reaction time of your

heating system. Please select beginning and end of each cycle accordingly.

How to Save Energy

.... by heating properly.

Aside from using the benefits of a modern heating system, you can increase your

energy savings with your own habits.

The following list may assists you:

� Ventilate properly

� Do not overheat

� Close all window shutters (if installed)

at dusk.

� Adjust thermostatic valves properly.

� Do not obstruct radiators and

thermostatic valves .

�Make use of the adjustment facilities of

the control unit .

� Adjust DHW temperature of the DHW

tank at the control unit .

� Controlled use of domestic hot water

Open window for a short period

completely with all thermostatic

valves closed.

Aim for a room temperature of 68 ºF /

20 ºC, each degree saves up to 6 %

heating costs.

E.g. alternating “normal room

temperature” with “reduced room

temperature”.

A shower typically requires less

energy than a tub bath.

... by performing maintenance regularly.

A regular maintenance check of your heating system by your heating contractor

ensures economical and environmentally friendly heating operation.

.... with effective insulation.

If you would like to make use of other energy-saving possibilities beyond the above

listed, check the insulation:

� of the heating system and DHW

piping.

� of your outside walls and roof.

� between heated and non-heated

rooms.

� of your windows.
