Dbx Zone Pro 640 Troubleshooting

[Eberardo Topher]

Hi, I have a Rachio 3, 16-zone controller I purchased and installed in 2019. Worked great last year. This year, I had the system turned on for the summer, irrigation guys were able to test using manual controls a couple of weeks ago when turning on the system. Now, I cannot power on any zone either manually at the controller, through app or via app timer. Rachio says the zone is watering but nothing actually happens.

If the first step checks out OK, then with the app thinking a zone is running, check that terminal against common for around 24VAC. Do for each zone. Also you can check and make sure there is no voltage on the zone terminals that you are NOT running according to the app. If you get strange readings, disconnect the control wires and check again (to double check it is the controller and not the wires/valves), may need to insert small wires into the terminals to assist in the measurement.

If the terminals are all checking good, then go downstream. Go to the valve box(es). With the zone not running, check the control wire for that valve for resistance to common. With the zone running in the app, check for 24VAC. Do that for every valve.

@TSGarp007 - clarifying what I meant manually - using the controls/buttons on the Rachio device vs. the app. I did not try playing with any valves yet, but will attempt to do so as you and @DLane have suggested. I will also check for power and shorts as you recommended and report back with findings. Thanks!

I know that I am not @Sujay, but thought I would jump in here. I would suggest first manually turning on each valve manually from the valve itself. This is usually done by turning the solenoid 1/4 turn counterclockwise. If the water turns on for each zone, then I would check out the common wire connections. If nothing, the water might seem to be off. We look forward to hearing back.

In an irrigation system using a Rachio controller, you should typically see around 24 volts AC (VAC) in the wiring when the controller is properly sending power to a zone. This voltage is used to activate the solenoids in the irrigation valves, allowing them to open and let water flow through.

Identify the Common Wire and Zone Wire: Locate the common wire (C or COM) and the zone wire you want to test. The common wire is usually white, while zone wires are typically different colors.

Turn on the Controller and Activate the Zone: Turn the controller back on and manually activate the zone you are testing. This can usually be done through the Rachio app or directly on the controller.

The problem that I have encountered is that even when someone schedules a meeting with me in their time zone, the reminder email then includes the meeting time in my time zone. It can be confusing and has resulted in missed meetings.

If that is not the case, has this been an issue with all or only specific invitees? If only specific, it could be related to their own device or browser settings, their email or calendar settings, or a result of them mistakenly booking in the wrong timezone due to a combination of those things. Even VPNs can mess this up! Let us know - we are here to help!

With calendar invitations, Calendly searches to find the invitee's local time zone, but sometimes cannot locate it or receives conflicting information. When this happens, the timezone on the invitation defaults to UTC.

Hey there, Calendly Community! I wanted to add to my own above comment about locking the timezone in your event type settings for those of you that are scrolling through this thread. The comment above is helpful - but not very detailed. I go over it in more detail, here, with written instructions and step-by-step screenshots for our more visual learners (like me!). See below for those steps!

I am trying to lock my time zone to Central since we are scheduling onsite meetings for a conference. I have set my profile time zone as Central but the time zone display keeps defaulting to East Coast (where I live). Not sure what else to try.

I would like to remove the time zone mention from my appointment confirmations. When clients receive the appointment confirmation, it should only show the time, like 15:00, without specifying "Middle European Time."

A few times each year we also have a team that travels to a tradeshow where we have potential customers schedule time to meet at our booth. These events are in different time zones from our main office that conducts the year-round trainings. Is there any way to have these tradeshow events be locked to EST while at the same time offering our trainings at MST?

Thank you so much. Great troubleshooting guide! Especially the point about VPNs affecting time zone detection. For those who struggle estimating meeting times across different locations, this app offers a time zone converter tool that can help ensure everyone's on the same page from the start!

Because some jurisdictions do not allow the exclusion or limitation of liability for consequential or incidental damages the preceding limitation may not apply to you. In any event the total liability of Clare Controls, LLC. shall not exceed the purchase price of the product. The foregoing limitation will apply to the maximum extent permitted by applicable law, regardless of whether Clare Controls, LLC. has been advised of the possibility of such damages and regardless of whether any remedy fails of its essential purpose.

The ClareOne 16 Zone Hardwired Input Module (HWIM), model number CLR-C1-WD16, allows the takeover of hardwired security zones making them compatible with the ClareOne panel. The HWIM has 16 hardwired zone inputs each with LED status, a tamper switch input, a back-up battery charging terminal, and 2 auxiliary power outputs for powered sensors, capable of outputting 500mA @ 12VDC. The HWIM supports powered and unpowered sensors, including contact zones (open/close), motion sensors, and glass break detectors.

Zone LEDs (red color): During "Normal Operation Mode" each LED remains off until its corresponding zone is opened, then the LED illuminates. When entering "Pairing Mode" each zone LED flashes briefly, after which each zone LED remains off until the zone is learned in. Once learned in, it illuminates until "Pairing Mode" is complete.

Only qualified installation technicians should install the HWIM. Clare Controls does not assume responsibility for damages caused by improper installation or use of the device. The HWIM is intended to be mounted to a wall using the included screws and anchors. The HWIM should be oriented with its antennas facing upward. The included antennas should be used regardless of location, for optimal RF communication. Once all sensors are wired to the HWIM, the HWIM and each zone can be paired to the ClareOne panel.

Note: If the HWIM is being installed in a metal container or equipment rack, the antennas must extend outside the container to ensure that the RF communication is not interrupted. Do not bend or alter the antennas

With a sensor in its active state (i.e. door/window contact separated from its magnet), take a multimeter set to measure resistance and connect the multimeter across the zone wires. If the multimeter reads a value of 10 kΩ or less, the sensor is N/O. If the multimeter reads an open or extremely high resistance
(1 MΩ or higher) then the sensor is N/C. The table below provides guidance for using the measurements to determine the EOL resistance value, as well as the line resistance for N/O sensors. This is the case regardless of the number of sensors connected to a single zone, so long as all sensors on the same zone are in series or in parallel with one another.

When pairing a zone, tripping any motion sensor that is not already paired to the ClareOne panel causes the motion sensor to pair in instead of the target zone. This includes pairing in the HWIM. We recommend pairing in motion sensors before pairing in the HWIM or other sensors. This includes wired and wireless motion sensors.

Note: When wiring a sensor that also has a tamper output, the alarm output and tamper output should be wired in series so that the zone triggers on either an alarm or tamper event. See figure below.

Troubled: The HWIM is offline, and nothing has been reported to the panel for 4 hours. At this point, for a monitored system the central station has been informed that the HWIM is offline. Typically, this is either due to power for the HWIM being removed or an object being placed between the panel and the HWIM blocking the RF communication path. Glass, mirrors, and appliances are the most common household items that cause interference.

Low Battery: The low battery indicator is only visible if the Battery Supervision setting is enabled for the HWIM, and the HWIM is either not connected to a battery, or the battery it is connected to is not adequate/low on charge.

Power Loss: When power is removed from the HWIM and there is a battery connected, the HWIM reports a DC power loss. This is indicated on the ClareOne panel as an alert notification. If there is no battery installed, as power starts to go down, the HWIM attempts to send out a power loss event signal to the ClareOne panel; in some instances the power loss event signal is fully received by the ClareOne panel and the alert notification is given.
