Accuracy, measurement range, electrical outputs, probe length and installation environment depend on variant and current revision. Check manufacturer data prior to equipment specification.
LFH10 indoor climate control
For indoor HVAC demand control, the LFH10 needs representative room airflow, isolation from direct heat sources and a stable electrical interface to the BMS. Confirm whether temperature and humidity are transmitted on separate outputs or over a shared protocol for the specified suffix. The model-name family does not establish exact sensor precision, calibration interval or protection against wet-process condensation.
LFH10 — room, duct or split RH/transmitter variants
| Humidity | 0–100% RH; accuracy ±3% RH at 20°C and 20–80% RH, ≤10 s response in slow air. |
|---|---|
| Temperature | 0–50°C or −20 to +60°C selectable; digital ±0.3°C over 0–60°C, resistive ±0.2–0.4°C typical at 25°C. |
| Interfaces | 4–20 mA, 0–10 V or Modbus RS485, order-code dependent. |
| Installation | Wall, duct or remote probe versions; IP65 rating with correctly installed seals. |
| Environment | −20 to +60°C, 5–95% RH non-condensing; ABS housing. |
Engineering note: The RH accuracy figure applies under the given reference climate rather than 0–100% RH. Supply wiring and a backlit display depend on analog/RS485 output choice; do not assume a 4–20 mA two-wire device has display backlighting.
