Many factors involved here; brand of tstat, branch pressure (depending what the tstat is actuating) DA?, RA?, day/night combination stat? ....... which one do you have?

If a thermostat is not working properly, you cannot calibrate it. It must be replaced.
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.
Johnson controls makes an amazing solenoid valve for this type of application
There are two ways to do this. Fist is there is a small nut located behind the heater coil on the thermostat. It takes a special wrench to turn this nut. You can get them where you buy your thermostat. The second way is to back off the screws that hold the backer plate to the wall and check it for level. Once it is level tighten the screws and connect the thermostat back to the backer plate.

A pneumatic thermostat is one that controls the air handling system by using an air-filled control tube to send signals. Pneumatic thermostats typically use a bi-metallic strip that responds to temperature changes, and correspondingly increases or decreases the air pressure in the control tube. Separate components within the air handling system respond to the pressure changes in the control tube to activate heating or cooling to occur through the ductwork.http://www.dr-fix-it.com/pneum1.html

how we calibrate the level switch
Pneumatic - as in pneumatic drill or pneumatic cannon is the correct spelling
What is the Pneumatic Railway
Pneumatic. Pneu = Air. Hydra = liquid
Pneumatic is a type of gas!
