SPECIFICATION SUMMARY
7507 series
CONTECA
®
EASY ULTRA
direct heat meter, compliant with directive 2014/32/EU (MID)
, for use in heating and air-
conditioning systems, with the following specifications:
ultrasonic
volume meter for hot water (maximum temperature 90 °C) with
pulse output, NTC type temperature probe, data viewing on 8-digit display, working temperature range 10–90 °C, protection class
IP 54, transmission via
TWO-WAY
Bus in accordance with M-Bus protocol over RS-485 or MODBUS RTU over RS-485, electric
supply 24 V (ac) 50 Hz - 1 W.
Options:
up to 2 additional pulse inputs - up to 2 pulse outputs.
Code 755810
Metering of refrigeration units. Upon activation of the software module, CONTECA
®
EASY is able to meter heating and cooling
units, on the evaluation of the temperature difference reversal, in separate registers for both the current values and for the
logged files.
Code 755881 – 755882
The single pulse output code 755881 or the double pulse output code 755882, allow transferral of heating and cooling energy
values to a generic logger.
The pulse weighs 1 kWh
. The pulse output with no potential is
open collector
with pulse time
120 ms - Vmax 24 V (dc) - 50 mA.
Code 755825
The optional pulse inputs (up to two) allow acquisition of generic meter consumption values (e.g. gas or electricity).
The generic
pulse input should be class IB,
with no potential
, maximum frequency 1 Hz.
Code 755826
Option for enabling DHW metering via checking of the flow rate scan for domestic water systems equipped with a recirculation
system. The option distinguishes the actual DHW flow rates from inaccurate or gross recirculation values, with the aim of providing
the exact domestic hot water consumption figure.
Code 755890
Electronic 8-digit LCD totaliser equipped with cover plate for
three-slot recessed electric box
. Lithium battery: life 8 years
- max. frequency 20 Hz. Suitable for pulse outputs code 75588.. Maximum cable length (2x1 mm
2
) (not supplied): max. 75 m.
Cable in dedicated raceway.
Code 755010
Compact touch-screen CONTECA
®
TOUCH controller, equipped with RS-232 - RS-485, USB and LAN port, with user
supervisor function (max. 250) and daily logging of consumption data. Enabled for the management of alarm and remote
activation SMS messages and for the automatic daily transmission of data to FTP server via email. Electric supply 230 V (ac).
Working temperature range 10–35 °C with no dust.
Code 750350
