- Now connect the connecting cable of the thermostat to a 230V mains socket.
- Position the end of the sensor cable at the most suitable point for temperature control.
Room temperature control
The sensor should be installed at half room height and should be freely suspended. The room temperature can only be optimally controlled when the sensor is not influenced by draughts, solar radiation or other heat or cold sources.
Cultivation of plants and seeds
Position the sensor in the soil close to the roots. The sensor must be surrounded by soil. In large plant pots, the sensor should be located in the middle of the pot.
Water temperature control
For water temperature control (e.g. in an aquarium), the sensor should be positioned in the central layers of water. Here, too, the sensor must be surrounded by water.
Operation
When installing, check that the unit or mains cable is not damaged. Also, make sure that the sensor cable has not become sharply kinked, as this may impair operation.
Switching on/off
As soon as the unit has been connected to the supply voltage, it can be switched on by means of the “ON/OFF” button. To do this, the button must be pressed for 3 seconds. Immediately after switching on the unit determines the ambient temperature of the sensor and indicates it on the display. To switch off, again press the “ON/OFF” button for 3 seconds.
Heat/Cool mode
It is possible to alternate between the heat and cool modes by pressing the “C/H” button. Keep the “C/H” button pressed for 3 seconds to change mode. On the display, “H” appears for 4 seconds for heating and “C” for cooling. At the same time, you can detect the mode that has been set by means of the LEDs. The red LED stands for heating and the green LED for cooling.
Setting the required temperature
Press the
button briefly to switch to the setting mode. The already set temperature now flashes in the display. Using the buttons, you can change the temperature in 1 °C steps. (Setting range: -50°C to +99 °C). After you have set a new temperature, it is saved automatically, and the menu closes after 3 seconds. Now the display again shows the current ambient temperature.
Operating modes
It is indicated by the yellow LED whether the heat or cool mode is active.
