Submetering

Q. Since there is no software to purchase with the Leviton HUB, would there be a software renewal subscription?

A: Not at all. Once the HUB is purchased, there no on-going cost for the end user to access data.

Q: Do we still use our Data Center to store data for the customer with the user license, or do we now offer a solution where a customer can download and interpret his/her own data?

A: All of the customers data will reside on the HUB locally until it is downloaded into their own server or PC for future use

Q: Can meters that are reading different voltage loads be combined for an aggregate load reading?

A: The HUB does not allow us to create "virtual meters" which is what you are suggesting. This can be done in most external software packages however.

Q: Is firmware on the Leviton HUB automatically updated if it's on a network open to the web?

A: Obvius periodically posts firmware updates to its website which the end user can periodically check and do an upload from there.

Q: Do we have the ability to add storage capacity to the HUB to meet code requirements of some jurisdictions?

A: There is no add on to the memory of the HUB at this time and so those jurisdictions requiring longer data back-up than the HUB can provide need to have a dedicated server that the HUB can push data to.

Q: Just so I understand your statement "without additional investment" the end user does not need to purchase our energy manger software to read the data? If so, how would the end user go about using the HUB for multi-tenant billing purposes?

A: Correct, to do what we did today, there is further investment. This product does not print bills however, so the end user has two options: (1) take month end data from this system and import to another billing system or (2) use our soon to be released Billing software, which will be an additional investment.

Q: If a meter is added, does the HUB automatically find it and add it to the device list?

A: It will appear attached to the I/O input, but it must be configured by the end user.

Q: Can you explain, in simple terms, the difference protocols like Modbus, DeviceNet, BacNet etc. and what protocols we don't support?

A: Each of these protocols are simply types of languages used by electronic devices to communicate sets of data between the device (meter) and the master (HUB). Each is slightly different, but they rely on tables or registers that format the data a certain way. Modbus is an old, well-worn and proven meter language that has been is use of many years. BACNet is relatively new and was created via ASHRAE to be more friendly with Building Automation Systems. They are very similar: Modbus calls their values "points" and BACNet calls their values "objects." I am not familiar with Device Net. We support MODBUS RTU at the moment. We do not support BACNet at this time, or DeviceNet for that matter.

Q: When will the lower cost Modbus-only HUB be available?

A: We can get it now, but it won't be Leviton green for 90 days or so (by June, 2012).

Sector 7 Ballast

Q: Can the Sector ballast be wired for both Mark 7 and Mark 10?

A: Sector 7 ballasts are 0-10V ballasts controllable ballasts only. They have termination for a switched line voltage and 0-10V control signal. This is akin to Phillips/Advance Mark 7. Mark 10 is a 2-wire phase control ballast and a different animal all together.

Q: Why do customers use 0-10V ballasts instead of 2-wire Mark X type ballasts?

A: Greater dimming range and better dimming performance.

Q: What is our warranty?

A: 5 year.

Universal Dimmer

Q: Is there an inrush when LED's are started? If so, what is the typical multiplier, and should we size the dimmer for it?

A: In-rush current occurs when switching electronic loads and it can be much higher than incandescent loads. We have evaluated the major lamp manufacturers to establish a baseline of in-rush current. Based on the available lamps on the market the Universal dimmer has been rated to operate safely up to 150 Watts of LED and CFL load. Example: You can operate up to 8 (18W) LED lamps and fall within the load limits of the dimmer.
