This means the module initiates the spark ignition sequence immediately when the thermostat or controller closes the 24V circuit

it provides superior resistance to vibration-induced stress and corrosion

once the signal rises above the set point

Signs of failure include visible cracks in the silicone insulation

While cleaning with a very fine abrasive (like a Scotch-Brite pad) can temporarily restore a microamp signal

Sporlan 168801 TXV 320788-702 This means the module initiatesThe Sporlan 168801, designated as model ERZE 12. 5 GA, is a high performance externally equalized thermostatic expansion valve engineered for precise refrigerant metering. This balanced port TXV is purpose built to maintain stable superheat across a broad range of operating conditions, making it ideal for systems with varying head pressures or high pressure drops across the distributor. With a 12. 5 ton capacity and optimized for R 410A refrigerant,
