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 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. Fig- ure 17- CLOSE).

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.
Coding switch There is a 4-pole coding switch on the DD2 backside. The meaning of the switches in particular is: Adaptive algorhythm activation. For reference see the chapter Adaptive algorithm (page 29). DD2 influences the direct heating circuit. DD2 influences the indirect heating circuit.
Check the resistance and connection of the sensors to eliminate the defect. DD2 signalizes error also when the DD2 isn’t syn- chronised with the controller (refer to the chapter Room unit synchronisation on page 3). INSTALLATION MANUAL...
