Digital dual thermostat STC-3008 range -55~120°C, 230V AC

Product detailed description

Digital dual thermostat - STC-3008 range -55°C~120°C, 230V AC. The thermostat allows the setting of T1 and T2 temperatures for two independent circuits, i.e. 2 × T1 and T2, where T1 is the temperature at which the thermostat turns on and T2 is the temperature at which the thermostat turns off. The thermostat tripping is indicated by the OUT1 and OUT2 LEDs.

Instructions for use:

To set the T1 temperature, long hold ^1 or ^2 depending on the setting of the desired circuit 1 or 2. Once the display starts flashing, the arrow keys can be used to adjust the switching temperature setting (preset 25 °C). To set the T2 temperature, hold 1 or2 for a long time. Once 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, the delay time for turning on circuit 1 (P0on display) or circuit 2 (P1on display) can be adjusted in the interval of 0-60min (preset 0min) and the high temperature (P2) or low temperature (P3) audible alarm can be sounded. The audible high and low temperature alarm is factory set to the thermostat limits, i.e. -55°C/+120°C. Simultaneously pressing ^1 and ^2 for 3sec. will reset the factory parameters.
Connect the supply voltage to the red (+) and black (-) wires, 12V appliances to the yellow and black wires.

Working modes:
- both circuits can also be set inversely, when T1> T2. Thus, by combining the circuits, many control methods can be obtained, e.g., in a certain temperature range to switch on heating and in another temperature range to switch on cooling.
- heating mode (T1- 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.

The product is not a separately functional unit, it requires professional assembly.
