Digital thermostat STC-3018, range -55°C~120°C, 230VAC

Product detailed description

STC-3018 is a dual digital thermostat that detects temperature using an external probe and switches one circuit via the output relay. You can regulate temperature in the full range of –55 °C ~ 120 °C; up to 99.9 °C it operates with a resolution of 0.1 °C, in the range of 100–120 °C with a resolution of 1 °C.

It includes a dual display, the red part of which flashes during setup. You can switch the thermostat between heating and cooling, set upper and lower acoustic alarms, and calibrate it according to the actual temperature. The sensors are waterproof. This is not a standalone device, so we recommend leaving its installation to a qualified technician.

Control and parameters P0 to P5:

• hold the RST button for 3 s – the thermostat will enter operating mode; holding it again for 3 s will turn it off (thus, pressing and holding RST turns it on and off), it turns on automatically after power is applied
• hold the S button for 3 s to enter setup mode; pressing it again will cause the red display to flash and you can use the arrows to select the desired value
• P0 – operating mode H/C (heating/cooling), factory setting heating
• P1 – hysteresis 1 °C ~ 10 °C, factory setting 2 °C
• P2 – upper acoustic alarm –55~120 °C, factory setting 80 °C
• P3 – lower acoustic alarm –55~120 °C, factory setting –55 °C
• P4 – temperature calibration (comparison with actual temperature and possible adjustment) –10 °C ~ 10 °C, factory setting 0 °C
• P5 – time delay 0~60 minutes, factory setting 0 minutes
