Tab. 3-1 (1/2)
3.1 Overview of the main operating parameters
It is imperative that you check the settings after the initial startup
Pos.
Parameter
Description / Explanation
RoCon HP
1.
Outdoor type
Set size of outdoor unit (even if it is not yet installed).
Read power (xx kW) from rating plate and set.
Ch. 5.2.1, Tab.5-1
2.
Indoor Unit
Set type of indoor unit.
Read type XXX from rating plate and set.
3.
Function
Heating Rod
When using an Heating Rod (electronic heating element) to
support the heat pump, please set to 1.
4.
Equilibrium Func
When activated, the electronic heating element for heating support
is first triggered below the external temperature set in the
parameter "Equilibrium Func".
5.
Room thermostat
When using a room thermostat (RT), you must set the parameter to
"On"; only the RT contacts on the circuit board (Connection J16)
also be evaluated (Interlinc fct). As soon as the parameter is
activated, the system runs only when the RT contact is closed in
heating-/cooling mode / frost protection function.
6.
Interlinc fct
Flow target temperature is adjusted when the second RT contact
(cooling contact, Connection J16) is closed to the value set in
parameter “T-Flow CH adj" or “T-Flow Cooling adj”
( RoCon HP, Ch. 5.2.2, Tab. 5-2).
7.
Max Perform
Pump
Defines maximum pump output
8.
Min Perform
Pump
Defines minimum pump output
9.
Power DHW
In order to expedite the heating process without an outdoor unit
and ensures the highest warm water comfort, set this parameter to
6 kW, or the maximum value of the built-in electronic heating
element.
Ch. 5.2.2, Tab.5-2
10.
BUH s1 / s2
power
Defines the output of the installed electronic heating element,
which is connected at the respective stage, and limits the output
that is taken for the heating support of the storage tank through the
mixing valve. If, during heating support with the electronic heating
element, the storage becomes too warm or cools off too much, a
sensor drift can occur. This can be counteracted by adjusting the
set parameter value according to Tab. 3-4.
11.
Insulation
Depending on the building insulation, the external temperature is
averaged over a specific time. Thus, it can happen that the heat
pump does not switch on immediately when the external
temperature falls below the parameter value "T-Outside lim day".
The averaged external temperature can be seen in the Info level
under info value “T-Outside".
Ch. 5.2.3, Tab.5-3
12.
T-Outside
lim day
If the averaged external temperature falls below this temperature, a
heating operation of the system is enabled (summer shutdown).
13.
Heat-Slope
Heat curve must be adapted for the respective house.
14.
Room Influence
When a room controller EHS157034 is used and a room
temperature-driven control is desired, this parameter should be
selected >0.
15.
1x Hot Water
After the target value is reached, this parameter MUST be
deactivated; otherwise, the storage is always kept at 37°C.
Recommendation: Always let this parameter be deactivated
(Setting 0)!
Ch.5.3, Tab.5-5
