About the Crestron GLXX-CTRL
Within a GLPX panel, the GLXX-CTRL controls the relay modules and communicates with the Crestron control system over Cresnet, handling up to 56 loads in total. Local controls allow testing and verification at the panel, override is available both locally and remotely, and the module has non-volatile power failure memory.
The module is designed for the GLXX-SW8 and GLXX-SW16 relay modules and the GLXX-HDSW8 and GLXX-HDSW16 heavy duty switch modules. When replacing a GLXX-CTRL, check which of these relay modules are in the panel and that the total number of controlled loads stays within 56.

Questions about the Crestron GLXX-CTRL
What is the Crestron GLXX-CTRL?
It is a Cresnet control module for Crestron's Green Light Express range. It controls GLXX-SW8, GLXX-SW16, GLXX-HDSW8 and GLXX-HDSW16 relay modules, handles up to 56 loads and forms part of a complete, Crestron engineered GLPX Green Light Express panel.
How many loads can the GLXX-CTRL control?
Crestron rates it to control up to 56 loads. Those loads are switched by the GLXX-SW8, GLXX-SW16, GLXX-HDSW8 and GLXX-HDSW16 relay modules that it controls within a GLPX Green Light Express panel.
Which relay modules work with the GLXX-CTRL?
Crestron lists four relay modules: the GLXX-SW8, GLXX-SW16, GLXX-HDSW8 and GLXX-HDSW16. The heavy duty GLXX-HDSW8 and GLXX-HDSW16 take GLR-HD-1P single pole or GLR-HD-2P double pole heavy duty relays. Together, the modules controlled by one GLXX-CTRL can switch up to 56 loads.
Does the GLXX-CTRL support override?
Yes. The GLXX-CTRL has both local and remote override capability. It also includes local controls for testing and verification, and non-volatile power failure memory, alongside its Cresnet link to the control system.
How does the module connect to the control system?
It uses Cresnet communications to link the Green Light Express panel to the Crestron control system. Within the panel it controls the GLXX-SW8, GLXX-SW16, GLXX-HDSW8 and GLXX-HDSW16 relay modules, up to a total of 56 loads.
How much is the Crestron GLXX-CTRL?
Crestron asks its dealers to give the price of the GLXX-CTRL directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.
Can 1Install supply, install and programme the GLXX-CTRL?
Yes. 1Install is an authorised Crestron Elite Partner with offices in Skerries, Co. Dublin and Cork. We can supply the GLXX-CTRL on its own, or install, set up and programme it as part of your system. Installation visits are €440 for 4 hours or €880 for a full day, plus VAT and travel.
Does the GLXX-CTRL come with a warranty?
Yes. Everything we supply is new, genuine Crestron with Crestron's standard warranty. If the GLXX-CTRL develops a fault, contact us and we will handle the claim with Crestron. If we installed it, our workmanship is guaranteed for the lifetime of the system.
Is the GLXX-CTRL in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the GLXX-CTRL without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
