Setting The Operating Mode - Daikin EHSX04P30A Operating Instructions Manual

Displaying the water pressure
On the Controller RoCon HP, when it is switched on, you can
display the system pressure (water pressure) in the internal
circuit (direct heating circuit). The water pressure is available as
the first info parameter (see fig. 3-6).
The permissible range of water pressure during operation de-
pends on the Daikin Altherma EHS(X/H) and the heating system.
The set values and threshold values must only be changed by the
heating technician. If the water pressure falls below the minimum
value (set parameter value), it must be increased by topping up
the system (see chapter on "Inspection and Maintenance").

CAUTION!
A heating system that is not frost-protected can freeze
in cold weather and may be damaged.
● Drain the water out of the heating system if there is
a risk 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".
