the R38999D018 ensures a precise fit and seamless integration with compatible furnace models

Belimo ZG-R03 Resistor Kit 318172-701 Automatic Reset Logic: The 40°FThe Belimo ZG R03 is a critical resistor kit designed specifically for field integrating MFT95 actuators into legacy 0 135 Ohm control applications. As a veteran technician knows, matching modern Multi Function Technology with older 135 ohm proportional controllers requires precise impedance matching to ensure stable signal response. This 135 ohm resistor bridges the gap between the high input impedance of MFT actuators and the specific current
