●
Place the rotary switch in the
"Operating Mode"
position.
An overview is displayed.
●
Select the desired operating mode with the rotary switch.
●
Confirm the changes with a brief push of the rotary switch.
Daikin Altherma EHS(X/H) operates in accordance with
the set operating mode.
The current operating mode is indicated by an appropriate
symbol in the standard display.
Operating mode Standby (Stand-by)
CAUTION!
A heating system that is not frost-protected can freeze
in cold weather and be damaged.
●
Drain the water out of the heating system if there is
a danger of frost.
●
If the heating system is not drained and there is a
risk of frost, the power supplies must be secured
and the external main switch must remain switched
on.
In this mode, the Daikin Altherma EHS(X/H) is shifted to the
stand-by mode. The
frost-protection function
(see section 3.6.5) remains in place. In order to maintain this
function, the system must not be disconnected from the mains!
All controllers integrated into the RoCon-system via the CAN bus
are also switched at a higher level to the operating mode
"Standby".
