Instructions for use:
The thermostat allows setting the temperatures T1 and T2 for two independent circuits, i.e. 2× T1 and T2, where T1 is the temperature at which the thermostat switches on and T2 is the temperature at which the thermostat switches off. The thermostat tripping is indicated by the OUT1 and OUT2 LEDs.

To set the T1 temperature, long hold ^1 or ^2 depending on the setting of the desired circuit 1 or 2. As soon as the display starts flashing, the arrow keys can be used to adjust the switching temperature setting (preset 25°C). To set the T2 temperature, long hold ˇ1 or ˇ2. As soon as the display starts flashing, the arrow keys can be used to adjust the switching temperature setting (preset 40°C).

By simultaneously pressing ^1 and ^2 in the setup mode, you can further adjust the delay time for turning on circuit 1 (P0 on the display) or circuit 2 (P1 on the display) in the interval 0-60min (preset 0min) and the high temperature (P2) or low temperature (P3) audible alarm. The audible high and low temperature alarm is factory set to the thermostat limits, i.e. -55°C/+120°C. Simultaneously press ^1 and ^2 for 3sec. to restore the factory parameters.

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

Working modes:
The two circuits can also be set inversely when T1 > T2. By combining the two circuits, it is possible to obtain many control methods, e.g. to switch on heating in a certain temperature range and to switch on cooling in another temperature range.

-Heating mode(T1 < T2): when the device is switched on, the thermostat output is switched on until the measured temperature reaches the T2 level. As soon as the measured falls to the T1 level, the output is activated again.
-Cooling mode (T1 > T2): when the device is switched on, the output is inactive until the measured temperature reaches the T1 level. Then the output is activated until the measured temperature reaches the T2 level.
