4. Operazione
4.1 Power-Up iniziale
Once wired, apply power to the controller. The display will illuminate, showing the current process value (PV) and set value (SV).

Figure 3: CHBMSS TC4M-N4N Display Example
4.2 Setting the Temperature (SV)
- Press u MODE button briefly to enter the set value adjustment mode. The SV display will flash.
- Aduprà u Su (▲) è Giù (▼) i buttoni freccia per aghjustà a temperatura desiderata.
- Aduprà u Left (◀) arrow button to shift the cursor for faster adjustment of individual digits.
- Press u MODE button again to confirm the setting and exit adjustment mode.
4.3 Impostazioni di i parametri (Avanzate)
To access advanced parameters (e.g., control mode, alarm settings, calibration), press and hold the MODE button for several seconds until the parameter menu appears. Navigate using the arrow buttons and confirm with MODE.
- Modu di Raffreddamentu / Riscaldamentu: Select between cooling (output active when temperature is above SV) or heating (output active when temperature is below SV).
- Calibrazione di a temperatura: Adjust the sensor reading to match a known reference temperature.
- Impostazioni d'alarme: Configure alarm thresholds (AL1, AL2) and alarm types.
- Max/Min Temperature Limits: Set upper and lower bounds for the adjustable temperature range to prevent accidental over/under-setting.
5. Mantenimentu
The CHBMSS TC4M-N4N Temperature Controller requires minimal maintenance to ensure long-term reliable operation.
- Pulizia: Pulite periodicamente u display è casincù un pannu dolce è asciuttu. Ùn aduprate micca detergenti abrasivi o solventi.
- Ispezione: Regularly check wiring connections for tightness and signs of wear or corrosion.
- Ambiente: Assicuratevi chì l'ambiente operativu resti in i limiti di temperatura è umidità specificati.
6. Risoluzione di prublemi
If you encounter issues with your temperature controller, refer to the following common problems and solutions:
| Prublemu | Causa Possibile | Soluzione |
|---|---|---|
| A visualizazione hè in biancu | Nisuna alimentazione o cablaggio sbagliatu. | Verificate i cunnessione di l'alimentazione è assicuratevi di u vulume currettutage. |
| A lettura di a temperatura hè imprecisa | Sensor faulty, incorrect sensor type selected, or calibration needed. | Verify sensor connection, check sensor type setting, perform temperature calibration. |
| Output not activating | Wiring error, control mode incorrect, or temperature not reaching set point. | Check output wiring, verify cooling/heating mode, ensure SV is appropriately set. |
| Allarme sempre attivu | Alarm set point too close to PV, or sensor issue. | Adjust alarm thresholds, check sensor accuracy. |
If the problem persists after attempting these solutions, please contact CHBMSS customer support for further assistance.
