Macon Controls has a solution that upgrades an existing thermostatic control operator while the heating system is functioning. 
There is no need to shut off or drain the system with the Macon UA. Just identify the existing thermostatic operator, select the 
Macon UA, add a Macon thermostat and your valve is upgraded to the Macon Controls standard of quality!
