LFH16 — wall, duct and remote-probe models

The LFH16 family contains LFH161 wall, LFH162 duct and LFH163 separated-probe variations; they are not the same mounting style simply because their electronics are related. Representative location, condensation exposure and probe lead routing control the usefulness of the humidity and temperature values. Compare the manufacturer’s ±3% RH normal-range specification with its wider-environment performance limits, and pair either 4–20 mA, 0–10 V or Modbus variant with the proper supply and BMS points.
