SCHNEIDER ELECTRIC 6921 Pneumatic Room Thermostat, Two-Pipe, Reverse Acting Cooling, 55 Degree to 85 Degree F Dial Range, 15 or 20 psi Supply Air Pressure

SINGLE SETPOINT PROPORTIONAL THERMO

The SCHNEIDER ELECTRIC 6921 is a Single Setpoint Proportional Thermo. This device operates by virtue of an orifice for sensing purposes and proportional control with a standard damper actuator.

A single setpoint proportional thermostat for cooling applications where a trigger is not required. Up to 15 psi air supply and 20 psi supply pressure. RTD sensor for superior control over non-contacting sensors. Equipped with a power failure transfer switch to preserve settings during power outages.

So many improvements, one thermostat. The 6921 is a proportional thermostat that lets you set just one setpoint and proportionally adds or shuts down system power to maintain the desired room temperature.

The 6921 is a single setpoint one piece, reverse-acting heating/cooling thermostat with proportional control. A quiet, high-impact plastic base is included. The 6921 has both NEMA 3 and 4X protection on the front face.

Smart Set Proportional thermostats provide superior performance and energy efficiency to control air conditioning, heating and domestic hot water distribution systems. The Smart Set family of digital programmable set point and proportional thermostats are designed for system balancing, occupant comfort and energy conservation with settings that can be customized using the web-based interface.

The 6921 series room thermostats are small, lightweight and simple to install. They have two single setpoint ports; 15/20 psi supply air pressure; a two-pipe design; and can be used with or without an auxiliary heat source (heat anticipator, timer).

Right temperature, right setting. The Low-Lead 6921 thermostat is an ideal replacement for two-pipe, proportional thermostat systems commonly used to automate industrial cooling applications. It provides wide range control from 55°F to 85°F (12°C to 29°C), and a 15/20 psi supply/return air pressure. With Schneider Electric's selection of communication options and a variety of mounting styles, the 6921 thermostat is designed to be uniquely yours.
