After the wiring connection, the DD2 shall be synchronized
with the controller. To synchronize the DD2, hold the key for
30 seconds. Release the key after two successive beeps . The
DD2 synchronization is now in progress. After another beep, the
DD2 is synchronized and the work can continue.
The signal cable length between the DD2 and the con-
troller must not exceed 50 metres.
DD2 shall be synchronized with the controller only after
all the temperature sensors have been connected.

Press and release key.
Press key to increase or decrease value.
The DD2 room unit is a modern designed and efficient device for
remote central heating control. It has the following features:
- selection of preset programs for room heating and domestic
hot water warming,
- operating mode selection,
- desired room temperature setting, and
- customer time programs for room heating and d. h. w. warming.
All measured temperatures and settings can be viewed on the
LCD display and modified. With the Party and Eco keys, the day
or economic temperature mode can be selected. The DD2 room
unit also enables the connection of an auxiliary temperature sen-
sor as well as remote activation via telephone.

Low batteries are indicated by the
symbol on the display. The batteries
should be replaced every 2 years. The
DD2 uses two 1.5 V type AAA alkaline
batteries as its power supply. The battery
socket is inside the ST1. To remove the
room unit from the wall plate, the room
unit shall be gripped in the height of the
keys and pulled off the wall plate (Figure
17 - OPEN). After the battery replace-
ment, put the DD2 back to the wall plate
by sticking it on top and pushing it with
its bottom towards the wall plate (Figure
17 - CLOSE).
Battery replacement
Command to quick save and quit (Escape)
Every time when the set-up mode has to be quit quickly, hold the
key and press the key. Release both keys after a beep.
