Function description
The main purpose of the CAN-EZ3 energy meter is energy management in conjunction with several
EHS(-R) electric immersion heaters and other actuators, as well as metering energy and heat.
Energy management primarily includes current measurement in the building and the corresponding
control of immersion heaters (and other consumers) for the use of surplus energy yields in the form
of DHW storage, instead of exporting it to the mains, which can be less profitable.
As the CAN-EZ3 has the full functionality of the x2 series and multiple sensor inputs, other tasks such
as heat and energy metering are also possible. However, only specific functions are used for the ac -
tual purpose of the energy meter and these are described in these instructions.
For tasks such as heat metering, 4 analogue inputs for temperature sensors, 2 inputs for VSG flow
rate transducers or FTS flow sensors and a DL bus interface for DL sensors are available.
The CAN-EZ3 is programmed either with
TAPPS2 , directly via the display and buttons on the energy
meter or remotely via the UVR16x2 controller, the CAN-MTx2 CAN monitor or the C.M.I.
Input values, system values from electrical measuring and results of the metering and functions can
be relayed to other devices via the CAN bus.
The same applies to values from inputs that are not used for any metering (e.g. in the case of a CAN
I/O module).
The CAN-EZ3 has
no outputs.
The CAN-EZ3 is not calibrated and consequently may not be used for billing purposes.
