White-Rodgers 1A16-51 Vstat

The White-Rodgers 1A16-51 is a heavy duty line voltage thermostat designed for high-capacity heating and cooling applications, including baseboard heaters and large electric fan-forced systems. This SPDT line voltage control provides reliable Single Pole Double Throw action, allowing it to manage either heating or cooling loads up to 25 amps at 120VAC or 22 amps at 240VAC. The temperature range of 36°F to 90°F makes it suitable for both standard comfort control and freeze protection in warehouse environments. Built with a rugged hydraulic action element, the heavy duty thermostat ensures precise temperature regulation even in demanding mechanical rooms. Its universal design replaces several competitive models, making it a staple for service technicians requiring a durable industrial HVAC control. The mechanical dial provides straightforward adjustment, while the robust switching mechanism handles the high inductive loads often encountered in commercial space heating installations.

• High-Current Capacity: Rated for up to 25A, making it ideal for direct control of high-wattage electric heaters without secondary contactors.
• SPDT Switching: Versatile terminal configuration supports both 'heat' and 'cool' modes for year-round application flexibility.
• Extreme Durability: The hydraulic action sensing element provides consistent performance in environments with high vibration or temperature fluctuations.
• Easy Installation: Standard vertical mounting and clearly marked terminals streamline replacement for the 1A11 series and other common industrial stats.

How do I wire the White-Rodgers 1A16-51 for heating applications?
For standard heating, wire the line to the common terminal and the load to the terminal that closes on temperature fall. Ensure the total amperage does not exceed the 25A rating for 120V circuits.

Can this thermostat be used for cooling or ventilation control?
Yes, because it is an SPDT control, you can use the terminals that close on a temperature rise to activate exhaust fans or cooling equipment when the setpoint is exceeded.

What makes the 1A16-51 different from standard residential line volt stats?
The heavy-duty construction and higher amperage rating allow it to handle significantly larger loads than standard units, which is critical for industrial electric heating equipment.
