Reverse Acting Unit Vent Thermostat

Description

The 2298 Series Unit Ventilator Thermostat has been
designed for the proportional control of pneumatic devices
and actuators in environmental control systems. These
devices are designed primarily as return air controllers in
induction units, fan coil units, and unit ventilators. The 2298
Series will also replace the obsolete 2264 Series Unit
Ventilator Temperature Controllers.
These two-pipe controllers incorporate a receiver controller
which when coupled with the highly-sensitive remote bimetal
sensor system, provides accuracy and stability over the
entire operating range. Models are available in direct or
reverse acting only, or dual pressure summer/winter models
for heating and cooling applications. (See Ordering Data.)
Set point adjustment is accomplished by means of a serrated
“thumb wheel”. A “cooler/warmer” cover with graduated
marks representing 5°F increments from 65 to 85°F is
provided with each controller.
