2.1.2 Solar support

The Daikin Altherma EHS(X/H) is prepared for integration into a
Daikin solar system.
The pressureless Daikin Solar-System
the case of Daikin Altherma EHS(X/H)B type systems the Daikin
Solar-Pressure system can be used.
The high performance flat collectors are highly effective in con-
verting solar radiation into heat, which is transferred via the solar
circuit into the integrated storage tank of the Daikin Altherma
EHS(X/H).
The heat that is fed in is transferred to the hot water circuit. If
there are sufficiently high temperatures in the hot water tank the
solar heat is also used for heating support. The RoCon HP
control unit controls this heat distribution fully automatically.

2.1.3 Safety management

The total security management of the Daikin heat pump system
is assumed by the electronic control integrated in the Daikin Al-
therma EHS(X/H). In the event of a water shortage, loss of refrig-
erant or undefined operating states, a safety switch-off is per-
formed. A corresponding fault signal provides an engineer with all
the necessary information for troubleshooting.

2.1.4 Electronic control

Depending on the heating unit, the RoCon HP electronic digital
controller automatically controls all the heating, cooling and hot
water functions for a direct heating circuit, a storage tank
charging circuit and, using optionally connected mixer modules,
additional heating circuits as well.
All function settings for the Daikin Altherma EHS(X/H) and the op-
tional equipment (terminal function) connected via the data bus
are performed by the operating elements of the RoCon B1 inte-
grated into the controls and are displayed in clear text on a col-
oured backlit ground.
The display and operation of a connected Daikin solar system are
performed by the associated controller for this component (e.g.,
Control and Pump Unit EKSRPS3B).
