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.
DD2 shall be synchronized with the controller only after
all the temperature sensors have been connected.
The signal cable length between the DD2 and the controller must not exceed 50 metres.

DD2 description
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 sensor as well as remote activation via telephone.

This command does not affect the program and service settings.
Battery replacement
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 replacement, 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).
The batteries should be replaced within 20 seconds. Otherwise, the
accurate time will have to be adjusted again.

Mounting location
The choice of the mounting location is essential for a proper DD2
operation. Suitable locations are inner walls which aren’t exposed
to direct sunlight, local heat sources and draught. The mounting
height should be approximately 150 cm above the floor (Figure 24).
Figure 24
Wall plate mounting
Remove the DD2 from the
wall plate by the following
procedure: hold the DD2 in
the height of keys with one
hand and the wall plate with
the other. Now pull both
parts apart (Figure 25).

INSTALLATION MANUAL
The DD2 room unit is intended for wall mounting. In case that no
connection box is installed, use the drilling template and mark drilling holes. Use enclosed screws to fasten the wall plate on the wall
(Figure 26). After the wires have been connected (see chapters
Wiring connections and Connecting the DD2 to a heating control-
ler), put DD2 back onto its base by sticking it on top of the wall
plate and pushing it with its bottom towards the wall plate (cf. Figure 17- CLOSE).

Wiring connections
WARNING: Mounting and wiring connections must be carried out
by a skilled heating engineer or an authorized company. Local
regulations or VDE 0100 and EN IEC 60364 regulations for electrical installations must be considered when the wiring connections
are carried out.
Bring the wires through the opening in the wall plate bottom (Figure
26- position A). Connect the terminals 1 and 2 on the room unit with
the controller terminals GND and COM (Figure 28). Use signal cables IY(St)Y 2×0,6 or LiCy 2×0,5 for connection.
After the wires have been connected, put the DD2 back on the wall
plate. A rectangular frame appears on the display (Figure 27). If
the rectangular frame doesn't appear on the display, the
communication between the room unit and the controller hasn't
been established. For troubleshooting refer to the chapter DD2
troubleshooting, page 32).

Behaviour with solid fuels
The DD2 signalizes by means of a beep that the solid fuel has
burned down—applies only for schemes 408 through 413 (S3 =
OFF, S7 = ON). The sound signal only functions when the day
heating mode is on ad the heating is active.
Necess ary DD2 setting:
- the beeper must not be turned off (P1.9 = - - -)
Adaptive algorhythm
The adaptive algorhythm automatically adapts the controller to the
controlled object by correcting the heat curve slope and a parallel
heat curve shift. The adaptation is carried out in accordance with
the average room temperature deviation and other data.

DD2 troubleshooting
The room unit automatically detects eventual malfunctions during
operation and displays them on the display. These errors are:
Er1, Er2, Er3 and Er4.
- temperature sensor defect
If appears on the display (Figure 30), it means that the builtin temperature sensor is defective. Send the room unit to the
nearest authorised service or dealer.
Figure 30
- defect of one or more sensors connected to
the controller
If appears on the display (Figure 31), it means that one or
more temperature sensors connected to the heating controller are
defective. Check the resistance and connection of the sensors to
eliminate the defect.
DD2 signalizes error also when the DD2 isn’t syn-
i
chronised with the controller (refer to the chapter Room unit
synchronisation on page 3).

INSTALLATION MANUAL
Figure 31
- defect in communication link with the controller
If appears on the display (Figure 32), the communication link
between room unit and controller hasn’t been established at all or
hasn’t been established properly.
Possible causes are:
- connection between the room unit and the controller is
interrupted. The rectangular frame does not appear on the
display (Figure 33). Check the connection between the room
unit and the controller.
- inappropriate communication speed between the room unit and
the controller. To eliminate this malfunction, set the parameter 6
in service group S2 (page 24) to the appropriate value 1.
