The APPLETON RS-2 is a Roof Sentry control unit designed to monitor and manage rooftop HVAC equipment. It provides automated sensing and control logic for rooftop units, helping protect equipment and maintain operational integrity under varying conditions. Licensed HVAC technicians and commercial rooftop equipment installers are the primary users of this control. The RS-2 is a direct-mount control device intended for integration into rooftop unit control circuits, delivering reliable switching and sensing performance in a compact form factor suited to commercial rooftop applications.
The RS-2 is used in commercial rooftop HVAC applications where automated equipment protection or monitoring is required. It is suited for installation on packaged rooftop units where a dedicated sentry control function is needed to supervise system operation. This part is appropriate for both new installations and service replacement scenarios on compatible rooftop HVAC equipment.
Designed as an OEM-style replacement Roof Sentry control for commercial rooftop HVAC units requiring RS-2 control functionality.
Installation of the RS-2 should be performed by a licensed HVAC technician familiar with commercial rooftop equipment control circuits. Disconnect and lock out all power to the rooftop unit before removing or installing any control component. Follow applicable local codes and the equipment manufacturer guidelines for control board wiring and mounting. Do not energize the unit until all wiring connections are verified and secured.
