192 S Single Setpoint
Pneumatic Room Thermostats
Features
• Single setpoint dial available in Fa.hrenheit or Celsius scales.
• Direct or reverse acting models
• Sensitive bimetallic element
responds to temperature
changes .
• Integral, adjustable limit stops.
• Wall mounting plate included for
easy connection to rough-in
boxes.
Applications
Designed for heating and cooling
applications for control of pneumatic valves and damper actuators, the
192 S Single Setpoint Pneumatic Room Thermostat is excellent for
commercial and institutional facilities.
These are available with both 1-pipe and 2-pipe configurations.
1-pipe: Use when limited output air capacity is required to operate a
single valve and/or actuator; requires external restrictor, 20 scim (5.4
ml/s) air supply.
2-pipe: Use for high output capacity for control of multiple valves and
actuators, used with or without high/low limiting controls.

192 HC Heating/Cooling
Pneumatic Room Thermostat
Features
• Dual setpoint dials available in Fahrenheit or Celsius scales.
• Direct or reverse acting models.
• Sensitive bimetallic element
responds to temperature
changes .
• Integral, adjustable limit stops.
• Adjustable changeover pressure.
• Large volume air capacity rela.y
Applications
Designed for temperature control of
heating and cooling applications, the
192 HC Heating/Cooling Pneumatic Room Thermostat controls valves
and damper actuators in cooling equipment. Providing energy
management and occupant comfort, the thermostat automatically
adjusts to seasonal changes from heating setpoint to cooling setpoint in
commercial and institutional facilities. It is available in a 2-pipe
configuration.

192 DN/DNV Day/Night/Vent
Pneumatic Room Thermostats
Features
• Dual setpoint dials available in Fahrenheit or Celsius scales.
• Direct or reverse acting models.
• Sensitive bimetallic element
responds to temperature
changes .
• Manual override selector for off-
hour occupant comfort.
• Adjustable changeover pressure.
Applications
The 192 DN/DNV Pneumatic Room
Thermostat controls valves and
damper actuators in cooling equipment, automatically performing
setback changes from day to night. The 192 DNV also performs a purge
sequence at night to bring in “vent” outside air to cool the building. A
manual override selector switch allows individual room or zone “day”
control locally during the night cycle. During the night control cycle, the
192 DNV models provide a separate output signal (full air supply)
allowing ventilation control. Periodic resetting to the “night” control
mode during evening or weekend periods using time clocks ensures
optimal energy management.

193 HC Free Energy Band Heating/Cooling
Pneumatic Room Thermostats
Features
• Dual setpoint dials available in Fahrenheit or Celsius scales.
• Integral, adjustable limit stops.
• Sensitive bimetallic element
responds to temperature
changes .
• Adjustable Free Energy Band.
• Wall mounting plate included for
easy connection to rough-in
boxes.
Applications
Designed for buildings with early morning heat requirements and mid-
morning to afternoon cooling requirements, the 193 HC Free Energy
Band Pneumatic Room Thermostat two temperature thermostat
controls valves, damper actuators and mechanical heating and cooling
equipment. Providing energy management and occupant comfort, the
thermostat automatically reduces heating load and increases cooling
load.
2-pipe (dual 1-pipe): Use when a limited air capacity is required to
operate a single valve and/or actuator.
3-pipe (dual 2-pipe): Use for multiple valves and actuators with or
without high/low limiting controls which require higher air capacities.
