The thermostat is recommended for control of electric heating devices or on/off valve actuator used in water-based system.

User Operation

• Power Key: Press the On / Off key to turn the system on or off.
• M Mode Key: You can select “period control mode” or “manual mode” by this key.
• Δ ∇ Up / Down key: Press the Up and Down keys to set the temperature and adjust system parameters. And press Up and Down simultaneously and hold for 5 seconds to enter lock key function.
• Clock key: You can adjust the time and the week by this key.
• Manual mode: Set the temperature manually by this key.
• Automatic mode: Adjust to the automatic mode, the thermostat will work cyclically by week programming.

Anti-frozen function

In the state of shutdown, the thermostat will turn on the heating device automatically When the room temperature is below 5°C. when the room temperature is above 7°C, the thermostat will turn off the heating device automatically.

Mounting Location Recommended

The heating thermostat should be mounted on the wall with air flowing freely around. Warning: The mounting location should not be influenced by other heat source (e.g., sunlight), air flow through doors& windows or temperature of outer wall.

Common failure handling

1. Check whether the battery is reversed.
2. Check if the power button is working.

LCD display garbled| he shell is deformed after installation, can be reinstalled.

1.  Check whether the wiring between the MPU and the power board is damaged.
2. Check whether the null line of live line is connected wrong.

Remote failure| Check if the remote-control battery has enough power, if not replace the battery.
Temperature display error| Adjust the panel temperature display by the first option in the Advanced tab.

MK71C DIGITAL DISPLAY PROGRAMMING HEATING THERMOSTAT

Attention: THIS THERMOSTAT IS SUITABLE FOR GAS BOILER. The temperature controller is using microchip real-time detection room temperature and target temperature contrast, control the wall-mounted furnace start or stop work, has achieved the purpose of constant temperature control. Weekly cycle, you can set 6 periods of programming run, each period with the corresponding preset temperature. You can select Cycle control mode or Manual mode as required.
