Fourtech Temperature Controller Manual [patched] Official

Universal input supporting Thermocouples (K, J, E, T, R, S, B) and RTDs (Pt100, Cu50).

Connect the AC live (L) and neutral (N) wires to the designated power terminals (typically terminals 1 and 2). Ensure the voltage matches the device rating. Sensor Input: fourtech temperature controller manual

Connect your external contactor loop across Terminal 3 (Normally Open) and Terminal 4 (Common) .

The manual walked Tom through the process of connecting the controller to his brew tanks and setting the desired temperature ranges. For example, the manual instructed him to set the temperature range for fermentation to between 18°C and 20°C (64°F to 68°F), and for conditioning to between 10°C and 15°C (50°F to 59°F). Tom was able to easily navigate the menu-driven interface and set the temperature setpoints for each tank. Universal input supporting Thermocouples (K, J, E, T,

Connect Terminal 5 (+) and Terminal 10 (-) directly to the DC input terminals of your external SSR. Initial Configuration and Parameter Settings

With the controller properly configured, Tom was able to monitor and adjust the temperature of his brew tanks remotely using the built-in RS485 communication port. He connected the controller to his computer and downloaded the Fourtech software, which allowed him to monitor the temperature of his tanks in real-time and receive alerts if the temperature went outside the set range. Ensure the voltage matches the device rating

If controlling a high-power heater, use a contactor. Do not rely solely on the internal relay for high current loads.

Regardless of the specific brand, "Fourtech" style controllers typically follow these setup steps:

For precise control and energy savings, you can connect a room thermostat. The installation instructions clearly outline how to do this:
