Nibe Heat Pump - allow the integration to work with a heat pump with modbus set to read-only

The problem I'm trying to add the Nibe Heat Pump integration with a Modbus TCP URL and get the error 'error on write request to pump' when adding the integration for a heat pump with modbus set to read-only. I tried the URL without and with Modbus TCP port 502. Is this a bug or a missing feature? The documentation doesn't say anything about the integration only working with a writable Modbus configuration. The source code looks like it's an undocumented limitation. My use case: I would like to use the integration just to gather statistics, i.e. only read information and not write anything / control the heat pump in any way. Modbus TCP is enabled on the Nibe heat pump and set to read-only. The heat pump IP is pingable from the Home Assistant Terminal extension.
