DewBuster™ Controller Configurations
On the order form you may select from several configurations listed, or you may select "Custom Output Configuration" and specify what you would like in the comments section of the order form. Here are a few configurations with recommendations:
1 Left TC + 1 Right TC + 6 MP + 2 PWR
This "default" configuration works well in many situations. Each Temp Controlled output has an input for a Temperature Sensor so the main scope can be run on whichever side is more convenient. The opposite side's Temp Controlled output can be used as an extra Medium Power output (no sensor plugged in) or as a Temperature Controlled output (sensor plugged in). The 6 Medium Power outputs should be enough for most scopes (if you need more then select 1 Left TC + 1 Right TC + 8 MP) and the two 12V Power jacks can power accessories.
1 Left TC + 1 Right TC + 4 MP + 4 PWR
This configuration is similar to above but provides more 12V outputs. If only one sensor is used then the opposite Temp Controlled output switches to Medium Power allowing a total of 5 heaters to be run at Medium Power.
2 Left TC + 2 Right TC
These configurations are useful in two special situations:
  • 14" or larger SCT's, large Mak's, or large refractors may need two heater strips on one lens. One Temperature Sensor can control both heaters plugged into that side of controller. The sensor is placed on the heater strip closest to the lens being heated. The combination provides extra power to warm the lens and once the proper temperature is reached it uses no more power than a single heater strip.
  • Large refractor with smaller refractor guide scope of similar construction. With properly sized heaters on each, the smaller scope should require the same power level from controller as the larger scope. So a single Temperature Sensor fitted to the main scope's objective lens heater (the most critical) can control both heaters plugged into that side of controller. Note that low power finder scopes should be run on Medium Power outputs.
Custom Configuration
Your DewBuster™ Controller may be customized to suit your needs. Just select the closest configuration on the order form then contact me to request a Custom Output Configuration and specifying which jacks are different. The default arrangement is shown above. When I process your order I will e-mail you a diagram similar to the one above showing the custom output jack arrangement so you can verify it is exactly what you want.

I recommended leaving L1 and R1 unchanged because they are associated with the Left and Right Temp Controlled LED's and Sensor input jacks. However if you really need these relocated it can be done.

Please note that custom configurations only change how the output jacks are wired. Custom configurations do not change the internal components or the type of jack (RCA only). It is not possible to have more than the two Temperature Sensor inputs already provided. I can add additional "Temp Controlled" jacks but they will be wired in with the Temp Controlled jacks on that side. There is seldom however any need for additional Temperature Sensors as only large heaters or heaters on primary optics will benefit from temperature control.

Please note that 12V POWER JACKS  are un-switched, meaning they will remain powered when the controller is turned off or when the Battery warning light is on and the heaters have been shut off. The 12V POWER JACKS are not voltage regulated so the output voltage will be that of the power source feeding the DewBuster™ Controller. The 12V POWER JACKS are fused by the DewBusterâ„¢ Controller's main fuse (16 Amp on HD Power Cord models, 10 Amp on Newtonian models) but if your accessory device requires a smaller fuse then it is your responsibility to add one.

Do not hesitate to contact me if you need assistance configuring your controller.
