• This controller automatically adapts to dual-voltage DC power input systems of 12V and 24V. For 12V DC systems, the maximum input voltage is 17V; for 24V systems, the maximum input voltage is 31.5V.
• The controller operates within an ambient temperature range not exceeding 50°C. If the controller housing temperature becomes excessively high, the compressor will stop to activate over-temperature protection (Recommendation: When ambient temperatures are high, implement forced air cooling for the controller).
• The controller's power input wires connect directly to the battery's positive and negative terminals. The controller's (-) terminal connects to the battery's negative terminal; the controller's (+) terminal connects to the battery's positive terminal. Failure to do so will prevent the controller from functioning properly. The controller features reverse polarity protection.
• The temperature switch is connected to the C and T terminals of the controller. If no resistor is connected between them, the compressor operates at 2000 rpm when the temperature switch closes.
• External Fan: A 12V DC fan can be connected between the controller's (F+) and (F-) terminals. The fan's positive terminal connects to the controller's (F+) terminal, and the negative terminal connects to the controller's (F-) terminal. When the controller's input voltage exceeds 12V, the output voltage between terminals (F+) and (F-) always remains at 12V. Regardless of whether the input voltage system is 12V or 24V, the fan must be a 12V DC fan.
