it should show a closed circuit

Can I use this wheel for both heating and cooling cycles

making it compatible with most HVAC controllers and legacy Siemens systems

Repeated tripping of the HH18HA497 is typically caused by restricted airflow

provided it meets local code requirements

Siemens Building Technology GDE131.1U Actuator 319852-301 it should show a closedThe Siemens GDE131. 1U OpenAir damper actuator is a robust, non spring return (NSR) solution designed for high performance control in building automation systems. Delivering 44 lb in (5 Nm) torque, this rotary actuator is specifically engineered for floating control (3 position) applications, making it a staple for managing airflow in small to medium sized dampers and VAV boxes. Working on a 24 VAC supply, it maintains a low power consumption of just
