For Keystone F784 AS-I modules.
Our new unit specially designed for replacing the Keystone F784 Mastermind, with all the functionality of the original.
Thanks to its simple design it allows fast replacement without the need for any changes on either the valve or its mounting slot. Just take out the old unit and reconnect the new one, and your good to go with the same controller for many years.
Made to run on AS-Interface 3.0 this allows for easy reintegration in the AS-Interface network.
