Instructions for use:
The thermostat allows setting the temperatures T1 and T2 for two independent circuits, ie. 2 × T1 and T2, where T1 is the temperature at which the thermostat closes and T2 is the temperature at which the thermostat turns off. The thermostat is closed by the OUT1 and OUT2 LEDs.

To set the temperature:

- hold T1 (^ 1 or ^ 2) for a long time, depending on the setting of the required circuit 1 or 2. As soon as the display starts flashing, the arrows can be used to adjust the switching temperature setting (default setting 25 ° C). Hold down ˇ1 or ˇ2 to set the temperature T2. As soon as the display starts flashing, the arrows can be used to adjust the switch-off temperature setting (preset 40 ° C).
- by simultaneously pressing ^ 1 and ^ 2 in the setting mode it is possible to further adjust the delay time of circuit 1 (P0 on the display) or circuit 2 (P1 on the display) in the interval 0–60min (default 0min) and the high temperature audible alarm (P2) or low temperatures (P3). The high and low temperature audible alarm is factory set to the thermostat limits, ie. –55 ° C / + 120 ° C. - by simultaneously pressing ^ 1 and ^ 2 for 3 sec. the factory parameters are restored.
- the offset of the measuring channel can be set by simultaneously pressing ^ 1 and 1v.

Connect the supply voltage to the red (+) and black (-) wires, the 12V appliances to the yellow and black wires.

Operating modes:
Both circuits can also be set inversely when T1> T2. This makes it possible to obtain many control methods by combining the two circuits, eg to switch on the heating in a certain temperature range and to switch on cooling in a different temperature range.

- heating mode (T1 - cooling mode (T1> T2): After switching on the device, the output is inactive until the measured temperature reaches the T1 level. Then the output is activated until the measured temperature reaches level T2.
- when you press and hold the up arrow, the display flashes and the setting of the appliance switching temperature is activated.
- after pressing and holding the down arrow, the display flashes and thus the opening temperature setting is activated.
- if the switching temperature is higher than the opening temperature, the thermostat is set to cooling, otherwise the thermostat will be set to heating.

The product is not a stand-alone unit, it requires professional installation.
