Can I clean the dual rod sensor instead of replacing it

The V47AE-13 is a direct-acting valve

then those pairs in parallel) to maintain the required 10k ohm resistance for the thermostat logic

The ZoneFirst RDP-12 is a professional-grade 12 inch round damper engineered for precision airflow management in residential and light commercial HVAC zoning systems

Siemens Building Technology QAC22 Sensor 326058-758 Airflow Optimization: Aerodynamic venturi designThe Siemens Building Technology QAC22 Sensor is a precision passive outdoor temperature sensor engineered for weather compensated control in high performance HVACR systems. Utilizing an LG Ni 1000 ohm sensing element (Ni RTD, 1k Ohm @ 32F), this unit provides a highly stable output signal across a wide operating range of 58 F to 158 F ( 50 C to 70 C). Designed for standard building automation systems, it accurately monitors outdoor air temperature
