8.4 Monitoring and configuration DIP Switch

WARNING!
Touching live parts can result in an
electric shock and lead to potentially
fatal injuries and burns.
Before beginning work on live parts,
disconnect all of the systems circuits
from the power supply (switch off
main switch, disconnect fuse) and
secure against unintentional restart.
Means with contact separation in all
poles that provide full disconnection
must be incorporated in the fixed
wiring in accordance with the wiring
rules.

8.5 Emergency operation

In the case of incorrect setting in the electronic control system,
emergency heating operation can be maintained by activating the
special "Manual Operation" function on the control unit (see op-
erating manual for the control unit).
If the 3-way valves are intact, the Daikin Altherma EHS(X/H)
switches to Heating mode. The necessary flow temperature can
be adjusted with the rotary switch.
Disconnect the system from the power supply.
Open the control housing and remove the RoCon BM1 board
(see chapter 4.5.7).
Check the DIP switch setting on the A1P circuit board of the
Daikin Altherma EHS(X/H), adjust where necessary
(see tab. 8-4).
The factory preset may only be changed if e.g. an
optional accessory was connected.
Replace the RoCon BM1 switch board, close the control
housing and reconnect the power supply.
DIP switch settings are not recognised until a brief inter-
ruption to the power supply.
