Revotec Retroswitch Air Conditioning Fan Switch - Rolls Royce / Bentley

The Revotec Retroswitch Air Conditioning Fan Switch controls your air conditioning system by managing the auxiliary fan operation and AC flap engagement based on engine temperature. It is designed to replace the original 'Otter' switch, activating the system only when coolant temperature reaches 44°C to prevent premature operation.Explore the key features of this replacement switch and how each function contributes to consistent air conditioning control:Direct Replacement for UE43063: Manufactured to replace the obsolete Rolls Royce and Bentley part number UE43063, this switch offers straightforward compatibility with no modifications required, allowing you to restore full function to the original fan and flap control system.Built-In 44°C Activation Threshold: Calibrated to engage only once engine coolant reaches 44°C, this temperature setpoint delays activation of auxiliary electric fans and the air conditioning flap, which reduces load during cold starts and promotes optimal engine warm-up.Internal Switching Mechanism: The internal contact design maintains consistent electrical control over the fan and AC flap circuit, ensuring reliable operation when the threshold temperature is met and helping avoid unnecessary fan cycling that could lead to wear or power inefficiency.This switch ensures your air conditioning system responds correctly to engine temperature, maintaining original operation characteristics across Rolls Royce and Bentley models. It s a smart choice to include in your climate control system restoration, providing reliable fan and flap activation control without altering the vehicle s electrical setup. A useful addition for keeping your cooling and AC systems functioning as originally designed.
