Frequently Asked Questions
Q1: How does the 4-parameter quick start menu simplify commissioning for electronic valve controllers?
A1: Setup requires configuring only four core parameters—refrigerant type, valve mode, pressure probe type, and application type—allowing rapid commissioning without complex manual calibration.
Q2: Can the EVD0000E20 driver connect to shared pressure sensors across multiple cooling circuits?
A2: Yes, the driver supports 4 to 20 mA low-power ratiometric pressure transducers whose output signals can be shared across multiple drivers to reduce sensor installation costs.
Q3: What safety mechanisms does the controller activate during abnormal operating conditions?
A3: The controller features built-in protection logic for low superheat, low suction pressure (LOP), and high condensing pressure (MOP) to prevent liquid floodback and compressor burnout.
Q4: What standard warranty applies to Ruifujie electronic control modules?
A4: All products across our entire catalog are backed by a standard 1-year comprehensive warranty.
Q5: What is the dispatch lead time for sample evaluations and mass production orders?
A5: Standard in-stock samples ship within 3 working days, while complete batch orders are fulfilled in 10 to 15 working days.
