I have 7 M1ZTS installed on M1G input zones 1-7. All are set for #33 temp, fast loop response and global loop response set for 40ms. Only zone 1 is available (default display when in temp sensors) for selection/viewing on the keypad, no others can be selected. I have validated M1ZTS’s are receiving over 13vdc of power, all have the same led indicator flashes. When I observe in RP current status, all 7 zones have an open voltage of approx 13.7vdc and cycle between shorted .6vdc and back to open voltage reading. What am I missing?
