Ambient Room Temperature Error

In order to make sure the reading is the most accurate the measuring device should be kept in the shade in the middle height of the room and in a well ventilated space that allows the air to circulate freely.

Ambient room temperature error. Refrigerant leakage detection. Both the indoor and outdoor units emit white mist possible causes. Another cause for a thermostat to be reading the wrong temperature in your home is a faulty temperature sensor. Overload current protection.

The graph above shows what happens when we took four different ir thermometers from normal room temperature into a space that was 50ºf lower. The cmm manufacturer will specify and ambient and with a nominal deviation a typical statement would be 68 degrees f plus or minus 2 degrees some machines will allow a larger spread such as 4 degrees or tighter spread such as 1 degree. A bad temperature sensor. In humid regions a large temperature difference between the room s air and the conditioned air can cause white mist.

H3 and e8 errors can occur when units are operating in high humidity high temperature environments. Also be sure to check and verify that filters exhaust ports and air inlets are clean and free from obstruction. Please check ambient temperature and ensure that temperature is below 90 f. If the ir thermometer is allowed to acclimate to the new temperature before being used it will provide fairly accurate readings.

However this one can be difficult to troubleshoot aside. E20 e50 general internal malfunction. Adjust room temperature or device location. When the unit restarts in heat mode after defrosting white mist may be emitted due to moisture generated from the defrosting process.

E0 0 e9 9 temperature module malfunction. The balance captures changes in room temperature that affect sensitivity and automatically starts calibration using built in weights. Evaporator coil temperature sensor t2 open circuit or short circuit. This ensures that sensitivity is constant at all times allowing the operator to concentrate on measurement tasks without having to worry about sensitivity calibration.

Controlled room temperature 20 c 25 c excursions between 15 c and 30 c are allowed ambient temperature 15 c 25 c or 30 c depending on climatic conditions. Temperature prevailing in a work area. Ambient temperature is the general room temperature that the machine is occupying. Condenser coil temperature sensor t3 open circuit or short.

Outdoor ambient temperature sensor t4 open circuit or short circuit. For technical questions inside the u s please call welch allyn at 800 535 6663.
