The TrolMaster DST-2 Temperature control modules allow the user to easily connect and control standard heating or cooling devices to the Hydro-x. Any heating or cooling device that is 10-amps @ 240 volts or less can be controlled by the DST-2.

<sub>LED status:
* Blinking green FAST: If the LED is blinking quickly, that means the module has not been addressed to the controller OR that module does not have a good connection to the controller. *Pressing the small button on the module will address/link the module when first installed.
* Blinking green SLOW: If you see a slowly blinking green LED, that means the module is addressed and connected to the controller, and the module is currently turned OFF.
* SOLID green: If you see the LED is on solid (no blinking) that means the modules are addressed, connected and currently turned ON.
* Blinking red: If you see the LED change to blinking red, that means the module has been overloaded. To reset the overload unplug the module from the power.</sub>
