3. Appliance description

The appliance is responsible for the processes that control and

regulate the heat pump. The appliance allows remote monitoring

and heating system control via the internet.

If multiple heat demands exist simultaneously, the appliance

switches back and forth between the demands. If a booster heater

is activated, DHW heating can run at the same time as the heating

mode and swimming pool heating.

3.1 Accessories

The following accessories can be installed for additional control

of the heat pump.

5.3 Network connection

Note

 Please note that, for example, ﬁrewalls and faulty

connections may cause problems that prevent full

functionality.

 If problems occur, contact your internet provider or

network administrator.

The appliance can be used to monitor the heating system via the

internet. For monitoring, you will need an internet connection,

a router and the Internet Service Gateway (ISG). Refer to the ISG

operating and installation instructions. Use of the ISG is only pos-

sible in conjunction with dynamic assignment of the IP address.

5.3.1 Connecting to the internet

 Connect a patch cable to the RJ45 connector (see chapter

“Commissioning / Connecting to the internet” in the operat-

ing and installation instructions for the heat pump).

5.3.2 Network settings

Note

 If multiple heat pumps are installed, the network

settings must be entered separately for each heat

pump.

Note

 If settings are required on a router or other network

component, contact the network administrator.

The connection can be established via DHCP or a static IP address.

Ensure that you select the same connection for all heat pumps.

 Press the button on the start screen to open the main

menu.

 Press the button.

 Select the “System settings” menu.

 Select the “Network settings” menu.

Connection via DHCP

Note

 Use dynamic assignment of the network address if

the heat pump is integrated in a network.

 Slide the switch to the corresponding position.

Connection via a static IP address

Note

 Use static assignment of the network address if the

heat pump is not integrated in a network.

Note

The router is only needed for setup via an external net-

work connection and for multiple secondary heat pumps.

Note

 Do not change the setting in the network mask

(255.255.255.0).

 Slide the switch to the corresponding position.

pump in the heating system.

5.4.1 Setting up the primary and secondary heat pump

Note

When connecting heat pumps of a different series, ob-

serve the instructions regarding the “SETTINGS”/ “Cas-

cade control” menu.

 Press the button on the start screen to open the main

menu.

 Press the button.

 Tap the button to access the “Cascade control” menu.

 Adjust the necessary settings.

 Confirm the selection.

 Select the “Cascade control” menu on the secondary

heat pump.

 Set the DIP switch to “Slave=0”.

 Assign a heat pump ID ≥1 to the secondary heat

pump. Assign IDs in chronological order for further

secondary heat pumps.

 Adjust the necessary settings.

 Confirm the selection.

 Follow the same sequence for additional secondary

heat pumps.

either

 Press the button to return to the higher ranking

menu.

 Press the button to return to the main menu.

 Press the button.

 Restart the primary heat pump.

 Restart the secondary heat pumps.

If there is communication between the primary and secondary

heat pump, the heat pump ID is displayed on the secondary heat

pump screen.

Example: Without external network connection (for cascades

with only one secondary heat pump)

Note

Monitoring via the internet is not possible.

 If you want to set up monitoring via the internet,

refer to the example “With external network con-

nection (for cascades with one or more secondary

heat pumps)”.

 Use an Ethernet cable (Standard Cat 5 network cable, RJ45

connector).

 Connect the heat pumps via the connection on the program-

ming unit. Observe chapter “Installation/ Removing the cas-

ing parts” in the operating and installation instructions for

the heat pump.

 Set the temperature up to which the booster heater will sup-

port the heat pump.

 Buffer cylinder conﬁguration

Start at heating curve demand

 Activate or deactivate the function.

When the function is activated, the contents of the buffer cylinder

are heated based on the heating curve.

Start at ﬁxed temperature offset

 Activate or deactivate the function.

When the function is activated, the contents of the buffer cylinder

are heated when the set temperature deviation is reached.

 Heat pump start offset

Can only be adjusted if the “Start at ﬁxed temperature offset”

function is activated.

 Set the temperature deviation at which the heat pump should

cover the heat demand.

 Booster heater start offset

Can only be adjusted if the “Start at ﬁxed temperature offset”

function is activated.

 Set the temperature deviation at which the booster heater

will support the heat pump with the heat demand.

 Summer mode permissible

Can only be adjusted if the “Start at ﬁxed temperature offset”

function is activated.

 Activate or deactivate the function.

If this function is activated, the heat pump is switched off when the

outside temperature falls in line with the set outside temperature

(see chapter “Further menus/ Heating settings”).

 Alarm control/central alarm

 Class

 External alarm input

 Class

 Choose which error categories are displayed and which trig-

ger the differential relay.

 External alarm input

 Activate or deactivate the function.

When this function is activated, an external error is registered.

Feedback %

 Activate system circulation pump

 Activate or deactivate the function.

 Circulation pump (HP) speed control

 Activate or deactivate the function.

When the function is activated, the pump runs within the deﬁned

speed range.

 Condenser pump continuous operation

 Activate or deactivate the function.

When the function is activated, the pump runs permanently. If

the compressor is not operating, the pump rate is dictated by the

settings under “Standby circulation pump (HP)”.

 Min. speed

Can only be adjusted if the function “Circulation pump (HP) speed

control” is activated.

 Set the minimum output at which the pump should run.

 Max. speed

 Set the maximum output at which the pump should run.
