Novelan Luxtronic heat pump binding

Documentation of the Novelan/Luxtronic heat pump binding Bundle

Introduction

For installation of the binding, please see Wiki page Bindings.

This binding was originally created for the Novelan heat pump. Since the Novelan control unit is based on the Luxtronic 2 contol unit of Alpha Innotec, this binding should work with all heat pumps that use this typ of controller.

Disclaimer

The whole functionality was reverse engineered via tcpdump, so use it at your own risk. 

Precondition

The heat pump bundle connects to your heat pump via network. Make sure your heat pump is connected to your network and the network settings are configured. To excess the network settings go in the heat pump Service menu -> system control -> IP address.

Generic Item Binding Configuration

openhab.cfg file (in the folder '${openhab_home}/configurations').

######################## Novelan/Luxtronic heat pump binding ###########################
# IP address of the heat pump to connect to
novelanheatpump:ip=

# refresh inverval in milliseconds (optional, defaults to 60000)
#novelanheatpump:refresh=

# port number of the heat pump to connect to (optional, defaults to 8888)
#novelanheatpump:port=

Please be aware that from firmware version 1.73, Alpha Innotec has changed the port to 8889!

Set parameters

These parameters can be changed:

• Heating operation mode
• Warm water operation mode
• Cooling operation mode
• Offset of the heating curve
• Target temperature for warm water

Sitemap example:

Switch item=heatPump_heating_operation_mode  mappings=[0="Auto", 1="Zuheizer", 2="Party", 3="Ferien", 4="Aus"]
