Frequently Asked Questions - RD1200-MOD-R Irritrol
How do I set the current time and date on the RD1200-MOD-R controller?
Press the "Time" button, then use the or keys to adjust the hour and minutes. Press "Time" again to switch to the date. Use the arrows to set the current month, day, and year. Finally press "Enter" to save. The controller will use this information for watering schedules.
How many stations can I connect to this controller?
The RD1200-MOD-R supports up to 12 stations. Each station represents a zone in your irrigation system. The modular design allows you to expand from a smaller number of stations to the full capacity as your system grows.
Can I connect a rain sensor?
Yes, the controller has a dedicated rain sensor input. Connect a normally closed rain sensor (e.g., Irritrol RS500) to the two terminals labeled SENSOR. Once installed, the controller will automatically stop watering when sufficient rain has fallen, and resume after the rainfall has ended.
How do I run a manual watering cycle?
Turn the dial to the "Manual" position. Use the or keys to select the station number you wish to water. Then set the watering duration using the arrows. Press "Start" to begin watering. The controller will water that station for the selected time and then return to Automatic mode.
What type of irrigation valves are compatible?
This controller is compatible with standard 24 V AC irrigation valves from most manufacturers. Each valve should have a solenoid rated at 24 V AC, with a maximum load of 1 A per station. Ensure the total load of all active zones does not exceed the maximum capacity of the transformer.
How do I reset the controller to factory defaults?
To perform a factory reset, turn off the power to the controller, then remove the backup battery if present. Wait 10 seconds, then reconnect the battery and restore power. This erases all programmed schedules and returns the settings to the original default values.
Is the RD1200-MOD-R suitable for outdoor use?
Yes, the controller is housed in a weatherproof enclosure rated IP56, making it suitable for outdoor mounting. However, to ensure longevity, it is recommended to install it in a sheltered location or use an optional protective cover.
Does the controller retain its programs during a power outage?
Yes, it features a backup battery terminal that accepts a standard 9 V alkaline battery (not included). This battery preserves the time, date, and program data during a power interruption. The battery is not used to operate the valves.
Can I expand the number of stations later?
Absolutely. The RD1200-MOD-R is designed with a modular architecture. You can start with a basic configuration and add expansion modules to increase the station capacity up to 12 zones. Each expansion module connects easily to the main unit without special tools.
How do I troubleshoot a zone that is not turning on?
First, check that the zone is properly programmed and that the station wire is securely connected. Use a multimeter to verify that the valve solenoid receives 24 V AC when the station is activated. Inspect the solenoid and valve for clogs or debris. If the voltage is present but the valve does not open, the solenoid may need replacement.
