Setting The Operating Mode - Daikin EHS157034 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 after the operating data overview 
(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 installation instructions of the Daikin
Altherma EHS(X/H), chapter "Inspection and Maintenance").
The pressure limits for the safety switch-off and the set
pressure can be adjusted in the parameter settings in
level "System ".
