TrolMaster revolutionized environmental controller technology when it introduced the Hydro-X. The Hydro-X Pro continues the revolution with a 10’ touch-screen and a web-based software. The Hydro-X Pro is backwards compatible with all current Hydro-X control / device modules. It also provides greater flexibility and allows any plug-in module to be addressed to be whatever the user wants. The user can also set up each plug-in module to have multiple “conditions” that will activate the module, allowing for almost unlimited control options.
