Lambda Heating & Cooling

This template allows you to control your Lambda Air-Water Heatpump without Gateway over Modbus TCP or RTU. There are three different ways how to connect Lambda with Loxone:

- Direct to the Heatpump without Gateway using Modbus TCP - Direct to the Heatpump without Gateway using Modbus RTU with Loxone Modbus Extension - Direct to the Heatpump without Gateway using Modbus RTU and Loxone Modbus Air.

Depending on variation of your project you can choose between Miniserver, Miniserver Go or Miniserver Compact.

The choice of paring Lambda Heatpumps with Loxone offers the possibility of:

- Integrating demand-based heating and cooling depending on e.g. presence or the protection of open windows - Active integration in interaction with e.g. PV- systems in a Loxone Energy Management - Using flexible electricity tariffs with the Spot Price Optimizer. - Use statistics or individual notifications - Create your own individual schematics - Reduce cycles and operating hours of your Lambda heatpump - Combining hybrid solutions e.g. Heatpump and PV- Heating element in your Hot Water Storage - Create e.g. yearly operation goals like certain annual runtime forces for hybrid systems e.g. (Heatpump 65% amount of energy, Gas heater 35% amount of energy) to fulfill the requirements of your local government. - Grid management according to §14a ENWG in Germany - In addition to the electrical power, the current and total thermal energy can also be visualized via the Loxone Energy Flow Monitor. To the compact overview for e.g. contractors. - Influence on the hot water circulation pump by controlling via the presence detectors. - Increased security through leakage detection or activation of IP cameras in the plant room.

With our step by step manual for collecting the heating or cooling demand and forwarding it to the Lambda Heatpump, we enable the interaction of the individual room control with the central heating/cooling system of Lambda.

Example UseCase: Residential building with Heating & Cooling Buffer, Hot Water Storage and two mixed heating circuits.

- Lambda Air-Water Heatpump EU13L - Heat/Cool Buffer storage - Hot Water Storage --> Controlled by Loxone - Mixing Circuit Heating (e.g. underfloor)--> Controlled by Loxone - Mixing Circuit Heating/Cooling (e-.g. ceiling) --> Controlled by Loxone
