Frequently Asked Questions - TH 10 Maico

How to install the TH 10 thermostat?

Installation must be carried out by a qualified electrician. First disconnect the power supply. Attach the lower part of the housing to the wall, connect the cables according to the wiring diagram, then replace the cover and rotary knob.

What is the difference between terminals 3 and 4?

Terminal 3 is used for Cooling mode (switching on temperature rise), terminal 4 for Heating mode (switching on temperature drop). The plug-in bridge allows selecting the mode.

How to set the setpoint temperature?

Turn the rotary knob [11] to set the desired temperature between -10 °C and +30 °C. The LED [2] indicates the relay switching status.

What is the purpose of the switching differential potentiometer?

The potentiometer [8] adjusts the difference between the activation and deactivation temperature (0.2 to 5 K). A smaller difference results in more frequent switching.

How to choose between heating and cooling mode?

Use the plug-in bridge [3] to select the mode: position H (Heating) or K (Cooling). By default, the device is set to Heating.

What does the LED on the device indicate?

The LED [2] is lit when the relay is energized (terminals 4 and 5 closed). It indicates that the thermostat is controlling the fan.

Where to place the temperature sensor?

Place the sensor in a representative location, away from drafts, direct solar radiation, and heat/cold sources (stove, radiator, window). Avoid mounting near heat-generating devices.

How to clean the thermostat?

Regularly clean the housing and sensor with a dry cloth. Do not use aggressive products or water.

What to do in case of malfunction?

Troubleshooting must be carried out by an electrician. First check the LED status and wiring. Do not attempt to repair yourself.

How to dispose of the thermostat at end of life?

Do not dispose of the device with household waste. Take it to an environmentally friendly collection point for electrical waste, in accordance with local regulations.
