Waterkotte ECO Touch Ai1 Geo

Installation

1. 1Connect the ModbusCloud gateway (MCG or MLP series) to the same local network as the Waterkotte ECO Touch Ai1 Geo heat pump.
2. 2Verify that Modbus TCP is enabled on the heat pump controller and note the IP address and TCP port (default is 502).
3. 3In the ModbusCloud portal, add a new device and import the Waterkotte ECO Touch Ai1 Geo template from the template library.
4. 4Enter the heat pump IP address and port in the gateway connection settings and confirm communication is established.
5. 5Check that all 37 registers return plausible values on the live data view, paying attention to temperature and pressure scaling.
6. 6Save the configuration and optionally set up alerts or dashboard widgets for the data points you want to track.

Things to watch for

01

The gateway cannot reach the heat pump over Modbus TCP. What should I check?

Ensure the gateway and the heat pump are on the same subnet or that routing is configured. Verify Modbus TCP is enabled in the ECO Touch controller settings. Confirm the correct IP address and TCP port (typically 502).

02

Temperature values appear to be 10x too high or too low. Why?

Temperature registers are int16 values in degrees Celsius, but some firmware versions apply a scale factor of 10 (0.1 degree resolution). Check a known temperature against the raw register value and adjust the scaling in the template if needed.

03

Can I change setpoints or switch operating modes through this template?

No. All 37 registers in this template are read-only. The Waterkotte Modbus interface does not expose writable registers in this configuration.

04

Will this template work with other Waterkotte ECO Touch models outside the 5005.5 to 5010.5 range?

It may work with other Ai1 Geo variants using the same controller, but this has not been confirmed. Test by importing the template and verifying that register values are plausible.
