A
Electric wiring of MODUSAT and VIEWSMART
The MODUSAT connection board is inside the unit shall be connected
to the ViewSmart by means of a 4x0.33 sq mm + shield cable
(BELDEN 8723) having a max. length of 25m.
Shield Termination
The Screening on the bus communication cable (RS Part no
528-2106). Connect together and put in terminal 'C'
This screening must be connected to earth at the amplifier at the start
of the run. The screening must not be connected to anything at the
end of the run. This will enable any electrical disturbance to travel one
direction down the screening to earth.
External Pumps & Valves
Pumps & valves must have a localised power supply. Switched neutral
connection to be fitted with 1amp in-line fuse on live cable.
Termination
Bootlace ferrules to be used for connections to the connection board
and ViewSmart.
Heating
When Evinox ViewSmart is used, Z1-C and Z2-C connections not
needed. Z1-C and Z2-C only to be used for 3rd party controller to
enable heating. Other configurations are available.
Zone valves and second ViewSmart controller
Zone valves and a second ViewSmart controller are only needed when
two zone are used. Current Part L1A Building Regulations stipulate
that all new heating systems in dwellings that are not open plan and
with area greater than 150 m² must include at least two heating
zones, each controlled by a thermostat and zone valve.
Keep Warm Facility and DHW cylinder schedules
When Evinox ViewSmart is used, P2-C connection is not needed for
KWF control. P2-C only to be used for 3rd party controller to enable
Keep Warm Facility or DHW cylinder schedules. P2-C can also be used
for 2nd pulse meter.
Electricity Meter
Electricity consumption displayed on the ViewSmart. Extra credits
towards BREEAM.
RS-485 or TCP/IP Communication
Depending on the project specification RS-485 or TCP/IP
