It operates on 24 Vac supply voltage (plus or minus 20%) at 60 Hz and accepts floating or SPDT control signals, making it compatible with a wide range of building automation systems and thermostats. The actuator delivers a 90-degree rotational stroke with mechanical adjustment available at 45 or 60 degrees in either clockwise or counterclockwise direction. Licensed HVAC technicians performing balancing, controls, and air-side work are the primary installers of this device.\u003c\/p\u003e\n\u003cp\u003eThis actuator is designed for use in variable air volume (VAV) terminal units and for mounting on ball valves in HVAC applications. It suits both residential and commercial HVAC control systems where reliable, non-spring return operation is required. The unit accommodates damper shafts ranging from 3\/8 to 1\/2 inch square or round profiles and can be wired to set the direction of rotation on opening. It operates within an ambient temperature range of 20 degrees F to 125 degrees F and a storage temperature range of 20 degrees F to 130 degrees F, covering a broad range of mechanical room and field installation environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-spring return design with 35 lb-in rated torque and 70 lb-in maximum stall torque\u003c\/li\u003e\n  \u003cli\u003eAccepts floating or SPDT control signals for compatibility with thermostats and building automation controls\u003c\/li\u003e\n  \u003cli\u003eMechanical stroke adjustment to 45 or 60 degrees in clockwise or counterclockwise directions\u003c\/li\u003e\n  \u003cli\u003eDirect-coupled aluminum hub with two set screws fits 3\/8 to 1\/2 inch square or round damper shafts\u003c\/li\u003e\n  \u003cli\u003eDeclutch mechanism allows manual operation without tools for commissioning or emergency use\u003c\/li\u003e\n  \u003cli\u003eExternal auxiliary switch capability available via accessory model 201052B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for direct coupling to damper shafts from 3\/8 to 1\/2 inch square or round profiles; suitable for use with SPDT or floating thermostats and building automation controls in VAV terminal unit and ball valve mounting applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage control wiring and air-side system controls. De-energize the control circuit and lock out the air handling unit before mounting or wiring the actuator. Confirm shaft diameter and profile compatibility before securing the aluminum hub set screws.
