Configure Climate states for Tuya TVRs

I have a number of Tuya TVRs on my radiator.
In Home Assistant, there are three HVAC states “Heat/Cool”, “Heat/Cool” again and Off
However, the logs show that other states are being passed:
2022-12-06 17:02:14.497 WARNING (MainThread) [homeassistant.components.tuya] Unknown HVAC mode ‘holiday’ for device Upstairs radiator; assuming it as off
2022-12-06 17:02:14.510 WARNING (MainThread) [homeassistant.components.tuya] Unknown HVAC mode ‘eco’ for device Upstairs radiator; assuming it as off

How can I change the device to read and set all HVAC modes?
I appear to have a lot more control of the devices from the Tuya app than from Home Assistant (e.g. battery levels, setting schedules etc…) - can any of these be accessed?
