Specifications & selection.
- Temperature setting 0–60 °C.
- Humidity setting range depends on the published specification variant.
- Heating demand is indicated when either temperature or humidity condition is active.

| Housing | Gray ABS; source specifies UL94 V-0 material |
| Operation / storage | 0–60 °C / −20 to +80 °C |
| Humidity / protection | ≤90% RH, no condensation or icing / IP20 |
| Condition | Published behavior |
|---|---|
| Temperature below lower threshold | Temperature indicator on |
| Temperature above upper threshold | Temperature indicator off |
| Humidity above upper threshold | Humidity indicator on |
| Humidity below lower threshold | Humidity indicator off |
| Either or both indicators on | Heating output demand on |
| Both indicators off | Heating output demand off |
Selection & installation notes
- The page contains incompatible supply, humidity-range and output-current specifications. Request the exact ETH11 variant datasheet before ordering; do not assume a universal 16 A load rating.
- The source does not define the parenthesized load categories in the detailed image. Confirm AC/DC and inductive-load limits, inrush and any required contactor.
- One relay combines the two demand conditions; this is not two independently wired control outputs. Confirm hysteresis, supply pinout and contact diagram on the supplied unit.
- Install in representative cabinet air and isolate both operating and load supplies before wiring. No variant suffixes have been invented for the listed supply choices.
Based on the official Chinese product page and selection charts ↗. Checked 2026-09-15. Confirm the current specification for the exact model when ordering.
