The time required for installation verification can be different based on the building type and its parameters
and can not be calculated in advance. Generally, two different situations can occur:
1. Received data are complete, it means all allocators and radio modules for water meters
were read. Units A can be fasten to the finally place using 4 screws and wall plugs.
Disconnect the batteries and connect the unit A to electrical network 230 V. Note:
connection of power supply NZCC1101 to electrical power network is secured by one
fuse, connection of wires according to label (N, L) must be kept (L is secured). Connection of device
to electrical power network or its maintenance can be done only by staff qualified in accordance with
local legislation.
2. System does not find all read devices from reading plan. To solve the situation, proceed step by
step and find the cause:
a) Check the plan first, i.e. if all mentioned units are really installed and repair the reading plan
if necessary. If some read devices should be removed from the reading plan, you can add
them to “List of ignored read devices”.
b) Check if the missing devices really transmit the data. The best way how to do it is to use
mobile reading unit RFU 35 with panel antenna to make reading from another place. If you
can read heat cost allocator or radio module for water meter using RFU 35, try to find new
position for unit A. After change of unit A location, restart unit B (by new upload of reading
plan). If heat cost allocators or radio modules for water meters can not be read even with
mobile radio reading unit RFU 35, it is necessary to check it on site.
