with cover.

TECH TIPto calibrate any pneumatic thermostat, perform the following:

1. Remove the cover.2. Measure the ambient temperature.3. Set the setpoint dial to the ambient temperature.4. Measure the controller output pressure (branch pressure).5. Turn the calibration screw(s) until the branch pressure equals the midpoint of the control span

[usually 8 psi (55 kPa)].6. Replace the cover.

ApplicationsThe134PneumaticHighandLowTemperatureDetectionThermostats are used on pneumatic heating and cooling systems in areas protected from the weather.

On a typical high limit application, the thermostat shuts down air conditioning or ventilating fans when the duct temperature becomes excessively high. A normally closed switch opens at setpoint.

On a typical low temperature application, the thermostat stops the fan or closes a damper when the temperature drops to the setpoint at any one foot (30.5 cm) or more of the sensing element.
