Product Overview
The AC8078 RF wireless digital thermostat is equipped with a high-precision internal NTC sensor to accurately detect room temperature. Communicating via a stable 868 MHz wireless frequency, it signals the dedicated receiver unit to automatically turn your heating device ON or OFF to maintain your desired comfortable indoor environment. By separating the temperature sensor from the hardwired boiler connection, the AC8078 provides the ultimate flexibility in placing the thermostat exactly where you spend your time.

Product Features
❄️ Anti-Frozen Function
When the room temperature drops to your set safety value (default 5°C), the thermostat forcibly turns on the heating device to prevent freezing pipes. Once the temperature is 2°C higher than the set point, it automatically turns off.
🚸 Child Lock Protection
Secure the thermostat interface via the parameter settings to lock all buttons, preventing unintended temperature adjustments or program changes by children.
✋ Manual Receiver Control
Press the ‘M/A’ button on the receiver for 3 seconds to enter manual mode (Green LED ON). This allows the connected boiler to be turned on or off manually using the Pairing button, bypassing the thermostat completely.
