Is Your Thermostat Placement Right Or Wrong?

If your thermostat is not mounted near the heat source, you risk the chance of getting false readings. No one wants that! That can lead to service calls or an application not working properly.

As far as bulb and capillary thermostats go, if you want accuracy, the bulb and the first two inches of the capillary tube must be inserted into the media. This applies to surface, ambient and liquid sensing.

If there is no bulb, the first 6 inches of the capillary tube must be near the point to be sensed.

Other important key factors to consider are:

• According to UL standards, the rate of temperature rise is at a rate of 1°F (0.5°C) per minute
• Do the volts and amps fall within the component specification?
• Are there any sharp bends or kinks in the capillary tube?
• Any unusual environmental conditions? High temperatures, low temperatures, fans blowing?

Make sure it is mounted properly and you are getting the readings you expect.
