How many zones can the MC-30E control?
The MC-30E supports 6 zones standard. You can expand to up to 12 zones by adding an optional slave module.
What power supply does the controller need?

Can I connect a rain sensor to the MC-30E?
Yes, the MC-30E has a rain sensor input. Connect a normally open or normally closed sensor to the terminals. Enable the sensor in the controller settings.
Why isn't my controller responding to button presses?
Check if the backlight is off; press any button to wake it. If it remains unresponsive, ensure the power cord is connected and the circuit breaker is on. Try resetting by unplugging for 10 seconds.
How do I clear all programming and start fresh?
Press and hold SET and ENTER simultaneously for 3 seconds. The display will show 'CLEAR?' Press ENTER to confirm. This resets all programs to factory defaults.
What does 'OVERRIDE' mean on the display?

How often should I replace the backup battery?
Replace the 9V alkaline battery annually or when the low battery icon appears on the display. Use a fresh battery to maintain time and program memory during power outages.
Can I use the MC-30E outdoors?
The controller is designed for indoor use but can be installed outdoors when placed in an weatherproof enclosure (sold separately). Avoid direct sunlight and rain.
