6. Impostazione
After installation and battery insertion, perform the initial setup:
- Accensione: Press the power button (if available) or ensure batteries are correctly inserted. The display will illuminate.
- Selezione dell'unità di temperatura: The thermostat typically defaults to Celsius. If Fahrenheit is desired, consult the detailed installation guide for specific button combinations to change this setting.
- Temperature Calibration (P02): If the displayed temperature does not match a known accurate thermometer, you can calibrate it. Access the calibration menu (often labeled P02 in advanced settings, refer to the full manual for access method) and adjust the offset. Confirm the change to save.
7. Istruzioni per l'uso
The CH112 thermostat offers simple operation for managing your indoor climate.
7.1. Setting Temperature Levels
The thermostat allows you to set three main temperature levels: Comfort, Economy, and Antifreeze.
- Temperatura di comfort: This is your desired daytime or active period temperature. Use the Up/Down arrow buttons to set the Comfort temperature. The display will show the set temperature, and the sun symbol will be active.
- Economy Temperature: This is your desired nighttime or inactive period temperature, typically lower than Comfort to save energy. Press the Comfort/Economy button (sun/moon symbol) to switch to Economy mode. Use the Up/Down arrow buttons to set the Economy temperature. The moon symbol will be active.
- Antifreeze Temperature: This is a minimum temperature setting (typically 5°C) to prevent pipes from freezing when the system is off or in a very low-temperature setting. This feature is usually automatic and activates when the ambient temperature drops below the preset antifreeze threshold.
7.2. Modalità di commutazione
- Comfort/Economy Toggle: Press the Comfort/Economy button (sun/moon symbol) to switch between your preset Comfort and Economy temperatures.
- Disattivazione: Press the OFF button to turn off the thermostat. The system will cease to regulate temperature, but the antifreeze protection may remain active depending on the model.
The thermostat regulates temperature with a precision of 0.1°C.
8. Manutenzione
8.1. Sostituzione della batteria
When the battery symbol on the display indicates low power, replace the batteries promptly to ensure continuous operation. The CH112 uses two AAA batteries.
- Open the battery compartment, usually located on the top or back of the thermostat.
- Rimuovere le vecchie batterie.
- Insert two new AAA batteries, observing correct polarity (+/-).
- Chiudere bene il vano batterie.
8.2. Pulizia
To clean the thermostat, gently wipe the surface with a soft, dry cloth. Do not use liquid cleaners, sprays, or abrasive materials, as these can damage the unit or interfere with its sensors.
9. Risoluzione Dei Problemi
- Il display è vuoto: Check if batteries are correctly inserted and have sufficient charge. Replace batteries if necessary.
- Thermostat not controlling heating/cooling: Ensure the thermostat is powered on and in the correct mode (Comfort or Economy). Verify wiring connections.
- Lettura della temperatura imprecisa: Ensure the thermostat is not exposed to direct sunlight, drafts, or heat sources. If the discrepancy persists, perform temperature calibration (refer to Section 6.3).
- System not turning off: Check the OFF button functionality. Ensure no other settings are overriding the command.
If issues persist after following these steps, consult a qualified technician.
