Congratulations on purchasing the Celestron Smart DewHeater
and Power Controller 4x. This controller delivers “smart” and
efficient power usage for up to four of your telescope system’s dew
heaters and up to four 12V DC devices while also providing cable
management for your setup. Plug all your dew heaters, power cables,
and USB cables into the controller. Then you can use one cable to
connect them all to your power source and another to connect them
to your PC, if desired.
If you prefer not to connect to a PC, simply plug your dew heaters
into the controller and power it on. The controller will automatically
monitor the ambient temperature and humidity using its integrated
environmental sensor. The thermistor port monitors the corrector
lens’ temperature and provides only enough power to prevent dew. If
you’re using battery power, this “smart” system significantly reduces
the heaters’ power consumption, extending battery life. If you would
like to manually adjust settings or monitor data, connect to a PC or
your Celestron mount’s hand control.
Please read through this entire manual before attempting to use the
Smart DewHeater and Power Controller 4x.
