Servicing The Thermostat Thermometer Adjustment The thermometer has been accurately calibrated at the factory and should only need adjustment if it has been dropped or mishandled. If the setpoint lever and the thermostat reading do not agree, follow the procedure below. Remove thermostat cover and open the flipup cover. Set the thermostat cover on a table near thermometer of known accuracy. Allow at least five minutes for cover thermometer to sense area temperature, then compare the readings. Be careful not to touch thermometer or breathe on it. If the readings are the same, replace cover and put the system into operation. If the readings are different, insert a small screwdriver in the thermometer slot, shown in Fig. 6, and turn it until both thermometers read the same. Replace thermostat cover and put the system into operation. THERMOMETER SLOT BACKSIDE OF FLIP-UP COVER INSERT AND TURN SCREWDRIVER M1810 Fig. 6-Thermometer adjustment. 21 69-0563-2
