2.2 Function Display
The function indicator of the Macon ZMC - ES (all around view) allows identifying the operating condition (valve open or
closed) at a glance. It is also possible to feel the current operating state when it’s dark.
• In case of the NC version, an extended function display
shows opening of the valve.
2.3 “First Open” function (for NC only)
In its delivery condition, the Macon ZMC - ES is kept open when de-energized due to the First-Open function. This enables
heating operation during the construction phase even when the electric wiring of the individual room control is not yet com-
plete. During the later electrical start-up, the First Open function is automatically unlocked by applying the operating voltage
for more than 6 minutes. The valve drive is now fully operable.
