      How many CT's can I have per unit for the CBUS current Measurement units (5504CMU & 5100CT80)

      4. However Multiple Current Measurements units (CMU's) can be added to the C-BUS network.

      How often is the information recorded in the C-Bus Current Measurement Units (5504CMU & 5100CT80)

      You can review your energy consumption by the hour, day, week or month.  You can also make comparisons with historical data.

      What is the warranty period for the C-Bus Current Measurement Units (5504CMU & 5100CT80)

      2 years from the date of installations (4 years when installed by an approved installer)

      What is the replacement for a 5500CN?

      The replacement for a 5500CN is 5500CN2.

      What are the C-Bus Channel Limitation for Current Measurement Unit?

      There will be limitations on how many CMU channels that can be utilized, depending on the device being used. This is due to memory limitations of those devices, as to how much historical data can be retained.

      Below is a list of the maximum CMU Channels that can be used. Each CMU has 4X Channels per unit.
      Each CT Coil has a selection range of either 0-40 and 0-80 AMP Range - This is software selectable..
