Product Description

The DAYTON Line Volt Mechanical Tstat (SKU 2NNR7) is an indoor single-stage control with a fixed 3°F differential and a temperature control range of -30° to 90°F. It features an SPDT switch action (open/close on rise), operates at 120V/240V/277V AC, and includes an 8 ft capillary with a 5 in x 1/4 in bulb. The steel enclosure houses this mechanical thermostat, which is designed for line-voltage applications.

Frequently Asked Questions

What is the DAYTON line volt mechanical thermostat used for?

The DAYTON line volt mechanical thermostat (2NNR7) is used for indoor single-stage temperature control in industrial HVAC and process applications. It directly switches line-voltage circuits (120V/240V/277V AC) to maintain setpoint temperatures between -30° and 90°F, making it suitable for heating or cooling systems in plant environments.

What are the specifications of the DAYTON 2NNR7 thermostat?

The DAYTON 2NNR7 thermostat has a fixed 3°F differential, SPDT switch action (open/close on rise), and operates at 120V/240V/277V AC. It includes an 8 ft capillary with a 5 in x 1/4 in bulb, a steel enclosure, and a temperature control range of -30° to 90°F. It is a mechanical line-voltage control for indoor use.
