Measured temperature and relative humidity are recomputed to following humidity expression: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy. Type Temperature Humidity Computed value H5021 H5024 H6020 The device is equipped with two relay outputs for alarming or controlling of external devices.
H5021 4. Device connection Notice: SP003 cable for setting of the regulator parameters via the PC's USB port does not provide the power supply. The regulator must be powered from an external source via terminals + U and GND. IE-HGS-H5(6)0XX-01...
5. Description of device function and setting 5.1. Device setting from the manufacturer Value assigned to Relay1 and Relay2: none Password for setting through keys: 0000 LCD display: value shown at first LCD line: temperature / CO - by device type value shown at second LCD line: relative humidity / dew point temp.
5.4. Actual regulator preset It is possible to display actual regulator preset on its LCD display by pressing of „“ key. LCD shows information about Relay1 and then Relay2 setting step by step. Information about Relay1 are indicated with symbol „ “, for Relay2 with symbol „...
Low limit „Lo“ – the relay closes when measured value falls below preset „low limit” for longer time than preset „delay time“. Relay goes open when measured value exceeds „low limit“ value plus the „hysteresis” value. See example. Low limit „Lo“ Delay [s] Hysteresis 5.5.
changed to its maximum / minimum value – for possible range see chapter „Technical parameters“ at page 16. Value can be changed with using „“ and „“ keys. Edited value is switched in “round” -9, -8, -7, …-2, -1, 0, 1, 2, …8, 9. To edit next number digit press „SET“ key, for moving back to previous digit press „ESC“...

Acoustic alarm deactivation activated acoustic alarm is possible to acoustic alarm is still activated for all time and deactivate by pressing „ESC“ key it is impossible to deactivate it Relay response for error Regulator continuously checks its state during operation. In case error of assigned value measurement is found then output relay: stays unchanged (in previous status) Relay1 switch OFF...

don’t show value on LCD show value on LCD Show computed value at LCD display This item provides to choice if actual computed value may be displayed at LCD display or not. There is shown the name of computed value on the top LCD line – see “Computed value selection“ below.
5.6. Restore to „Factory default“ – measurement part This item provides regulator restoring to factory setting. Press „SET“ key, select „YES“ and confirm it by pressing of „SET“ key. It reset regulator parameters to following values: Value assigned to relay 1 and relay 2: none Password for setting through keys (PASS): 0000 display:...
If specific enthalpy is selected, there is shown only value (number) without corresponding unit 8. Preventive maintenance and calibration Pay heed to recommended calibration interval. Do not subject the device to mechanical stress. Recommended calibration intervals: H5021 5 years (CO H5024 5 years (CO...
