How to Set Up
- Connect 220V AC to power input terminals
- Wire load to relay output (COM/NO/NC)
- Power on and select HUM or DEH mode
- Set desired humidity level using UP/DOWN buttons
- Adjust hysteresis if needed (default 3% RH)
Default hysteresis is 3% RH to prevent rapid cycling
For critical applications, set to 1% for tighter control
Use qualified electrician for installation
Modes Explained
HUM Mode: Relay activates when humidity falls below setpoint (humidifier runs)
DEH Mode: Relay activates when humidity rises above setpoint (dehumidifier runs)
Important Settings
| Parameter | Range | Default |
|---|
| Setpoint (H/S) | 0-99% RH | 50% |
| Mode (COD) | HUM/DEH | HUM |
| Hysteresis (DIF) | 0.1-9.9% | 3.0% |
| Calibration (CAL) | ±9.9% | 0.0% |
= Calibration Instructions =
Press and hold SET for 5 seconds to enter menu, navigate to CAL parameter, adjust offset to match reference hygrometer, press SET to save.
Positive offset (+) increases displayed reading
Negative offset (-) decreases displayed reading
Calibrate annually or when accuracy issues arise

Safety Precautions
Installation by qualified electrician only
Disconnect power before wiring connections
Do not exceed 10A current rating
Keep away from water splashes and direct sunlight
Do not use in explosive or flammable environments
Ensure proper ventilation around controller
Do not attempt to open or modify the unit
For loads exceeding 10A, use an external contactor or relay
Install at least 2 meters above floor level for best sensor performance
Avoid installing in areas with chemical vapors or condensation
Troubleshooting Common Issues
"ERR" or "-" display - Sensor connection issue or sensor failure
Relay not switching - Check power supply and wiring connections
Inaccurate reading - Perform CAL adjustment or relocate sensor
Blank display - Check power input and fuse
Relay clicking rapidly - Increase hysteresis (DIF) setting
Cannot change settings - Press and hold SET for 5 seconds
For "ERR" error, try resetting by power cycling the unit
If problems persist, contact manufacturer for support
