The Thermistor for Smart DewHeater Controllers is required for automatic

“smart control” of a non-Celestron heating band or heating strip with the

Celestron Smart DewHeater Controllers. The thermistor allows the controller

to detect how much heat the heating band is applying to the telescope.

Along with the controller’s integrated environmental sensor, the thermistor

helps determine how much power the heating band needs to keep the

optics free from dew. This system provides the most efﬁcient power usage

for dew prevention, greatly extending battery life. If you choose not to use

the thermistor, you can only set the heating band power manually. If you are

using a Celestron Dew Heater Ring, this thermistor assembly is not required,

as the ring already has a built-in thermistor.

If you are using another manufacturer’s heating band or strip, it needs an

RCA-type plug to connect to the controller’s heater output ports. Connect

the heating band to the telescope and connect its plug to one of the

controller’s dew heater ports. Then, place the tip of the probe thermistor

under the heating band (Figure 1). We suggest using tape to secure it ﬁrmly

in place.
