In order to ensure that the fault has not been caused by 
incorrect setting, set all the parameters back to the 
factory settings before possible replacement of compo-
nents (see chapter 3.6.12).

If you are unable to determine the cause of failure 
yourself, Daikinplease consult a service technician.

Have the significant equipment data to hand 

(see fig. 7-4 for the procedure):

– Type and manufacturer number of the Daikin 

Altherma EHS(X/H)s (see heat pump identifica-
tion plate).

– Software versions (see fig. 7-4) of:

a: Control unit RoCon B1 [Sw Nr B1/U1]

b: Circuit board RoCon BM1 [Sw Nr Controller]

c: RTX-AL4 circuit board [Sw Nr RTX RT]

– On optional RoCon system components:

Emergency operation

In the case of incorrect setting in the electronic control system or 
malfunction of the 3-way diverter valves, emergency heating op-
eration can be maintained by activating the 

special "Manual Op-

eration" function

 on the control unit (see chapter 3.5.1 and the 

supplementary instructions in the installation and mainte-
nance manual

 of the Daikin Altherma EHS(X/H).
