Ranco C12-5010 Temperature Control

The Ranco C12-5010 Temperature Control is a heavy-duty, single-stage SPDT mechanical thermostat designed for precision cycling in PTAC units, through-the-wall air conditioners, and packaged terminal systems. Engineered to replace a wide variety of OEM room air conditioner controls, this unit facilitates reliable on/off compressor regulation across a 60°F to 98°F temperature range. It features a 36-inch capillary tube with a 3/8" x 9" sensing bulb, utilizing a laser-welded stainless steel element for maximum sensitivity and response. With a 3°F fixed differential, the C12-5010 ensures tight environmental control, preventing short-cycling while maintaining consistent comfort levels. Built for versatile field installation, this line voltage thermostat handles up to 20A at 240V AC, making it a robust choice for technicians servicing residential and commercial HVAC units. Whether you are performing a retro-fit or a direct component swap, this Ranco heat/cool control provides the electrical switching reliability required for high-demand compressor duty.

• Universal Compatibility: Expertly designed to replace many hard-to-find OEM PTAC thermostat controls in older and modern units.
• Precision Sensing: Equipped with a 36" capillary and stainless steel sensing element for accurate remote temperature monitoring.
• High Electrical Rating: Rated for up to 20A at 240V and 16A at 277V, ensuring heavy-duty compressor switching performance.
• Flexible Application: The SPDT switch action allows for use in both cooling-only and heat/cool configurations with an external changeover switch.

• What is the primary application for the C12-5010? It is specifically matched for through-the-wall units and packaged terminal air conditioners (PTAC) to govern compressor cycles.
• Can this replace a different Ranco C-series control? Yes, it is common to use the C12-5010 as a replacement for various single-stage Robertshaw and Ranco models with similar capillary lengths.
• Does this include a mounting bracket? This control is typically used as a direct internal component replacement; refer to existing chassis hardware for mounting.
