Calling Climate: Set target temperature resets DST settings

The problem

I am using the NuHeat integration on HA 2024.5. When I call the service "climate.set_temperature":

service: climate.set_temperature
target:
  entity_id:
    - climate.master_bath
data:
  temperature: 60

The "Use Daylight Savings" setting on the NuHeat Signature thermostat becomes unchecked, and the time resets back to Standard Time. This causes a problem because the thermostat thinks it is an hour earlier and the program doesn't run at the correct time.

What version of Home Assistant Core has the issue?

core-2024.5.3

Further testing reveals this is entirely on NuHeat; using their app to change the target temperature also causes the DST setting to disappear. I'll open a ticket with them.

I'll add a comment/solution here in case anyone else has this issue. So far, it appears that not using the DST setting and turning off network time sync allows the temperature and hold/run settings to work without changing the time. You'll need to change the time on the thermostat(s) for every switch to/from DST, but at least the clock won't change on you unexpectedly.
