The TrolMaster DSP-1 program device module (timer module) works like a multi-function irrigation timer. The timers for the DSP-1 can be set to activate at specific times of the day or night, as well as configured to function as a recycling timer with or without a maximum number of cycles setting. The DSP-1 can also be used as a “master pump” controller on the Aqua-x. A master pump would be plugged into the DSP-1. When connected to the Aqua-x 24vac module, the DSP-1 will automatically turn on the pump when any of the 24vac irrigation zones are activated.

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.
