External temperature sensors vs. wall-mounted thermostats?
To avoid excessive cycling of mini-splits, there has been a lot of discussion of using wall-mounted thermostats. For example:
What about using external temperature sensors instead?
Seems like they would be a less expensive option to address the cycling issues (provided wiring is available from remote locations to wall-mount mini-split heads). Handheld remotes could still be used for control functions such as settings and scheduling.
For Mitsubishi, for example, see:
Remote M-Series Ductless Temperature Sensor
Remote Blank Plate wall mounted temperature sensor. Replaces the Return Air Temp Sensor and plugs into the respective connector on the indoor unit control board.
The Flush Mount Remote Temperature Sensor (PAC-USSEN001-FM-1) is used to discretely measure space temperature from 100 feet away from Mitsubishi Electric Equipment. Production: 2018 – Current
The PAC-USSEN001-FM-1 is new and particularly interesting, because it can be essentially invisible. Unfortunately, for some reason, it doesn’t seem to be compatible with FH mini-splits. Maybe a new version will be forthcoming.
Anyone have experience or insights regarding use of such external temperature sensors?
