Preliminary recommendations
Comply with the ollowing instructions for installation and examine the installation diagram.
Failure to observe these instructions may invalidate warranty and correct measurement of the
thermal energy.
1 Installing the SENSONICAL ULTRA series heat meter requires fitting the probe holder valve
code CAL19180 or the TEE code CAL19181 in the system on the flow pipe, observing all the
instructions on the relevant instruction sheet.
2 The flow temperature probe must be inserted in the probe holder valve or in the TEE so that
it reaches the centre of the pipe. Make sure that the probe does not touch the bottom. The
immersion depth can be adjusted by means of the nipple.
3 The SENSONICAL ULTRA meter must be installed by technically qualified personnel.
4 The meter must be positioned on the pipe at a distance of more than 200 mm from motors,
switches and regulators and more than 50 mm from electrical cables in compliance with the
requirements of the EC directive on electromagnetic compatibility and to ensure interference-
free operation.
5 Flush the system before inserting the hydraulic section.
6 The correct positioning of the hydraulic section of SENSONICAL ULTRA is on the return
pipe; attention must be paid to observe the correct direction o the low. The temperature
probe not sealed to the template of the volume meter must necessarily be inserted in the
pocket of the valve CAL19180 or TEE CAL19181 on the system flow line. Consider also that
the length of the flow probe cable is equal to 1.5 m and that it can be neither extended nor
shortened; if it is too long, it is advisable to wind it and secure it with a plastic cable tie.
Before and after the meter there must be shut-o ball valves in case it needs to be replaced
or inspected. A strainer upstream of the system is necessary in order to prevent any
blockages.
7 We recommend installing a venting device: air bubbles can cause measurement errors.
8 Clean the instrument only if required using a cloth moistened with water.
9 When positioning, consider the risk of water dripping onto the electronic component of the
heat meter.

Installation – Volume meter
aClose the upstream and downstream shut-off valves nearest to the point where the
SENSONICAL ULTRA heat meter is to be installed.
bOpen the nearest drain valve to decrease the pressure.
cRemove and empty the tube portion where the hydraulic section of the SENSONICAL ULTRA
is to be installed.
dTake out the old seals and remove any residues.
ePosition the new seals.
Install the volume meter on which the tailpiece-nut fittings have previously been secured
observing the direction of the flow (check the direction of the arrow on the instrument).
gTighten the fitting to a suitable torque for the seal supplied.
hTurn the electronic unit into the correct position for reading.
Installation – low temperature probe
aIf installing in a dedicated probe holder valve, close it, if in a probe holder TEE, close the
nearest shut-off valves.
bRemove the cap on the probe connection and clean the surfaces to remove any residues.
cRemove the O-ring from the probe and place it on the probe connection of the ball
valve/TEE.
dInsert the probe and adjust its depth of immersion by means of the nipple.
eTighten until it stops.
Commissioning the meter
aSlowly open the shut-off device, check the hydraulic tightness and functionality of
SENSONICAL ULTRA, and clean the electronic unit if needed.
bVerify the operation of the display by pressing the front button.
cAfter verifying the instrument works properly, apply the seals on the temperature probes and
on the volume section of the flow meter.
dIn case the heat meter has to be replaced, note the last displayed consumption data and the
serial number of the instrument being replaced and of the new one as well as all the previous
readings stored in the instrument deemed necessary.
Connecting the two additional pulse inputs (CAL19185MI)
The pulse inputs enable acquiring the consumption of hot and cold water from two volume
meters, according to the following wiring diagram:
IE: pulse input
In pulse emitters with an open collector output it is mandatory to respect the polarity. During
installation, the conductors must not touch one another to avoid that the instrument logs
the pulses.

Disp ay readings and information
The electronic unit is equipped with a liquid crystal display with 8 digits and special characters.
The data that can be displayed are split into three levels and can be viewed using the selection
button. The standard mode (without pressing the button) shows the total heating and cooling
energy consumption since the startup of the instrument (alternating views).
The main level is automatically displayed first. Pressing the button for more than 4 seconds takes
you from one level to another.
Pressing briefly the button allows you to scroll through the data for each level.
If the button is not pressed for one minute the main level is automatically displayed.

Error codes
When the instrument detects an error it displays the error symbol and the relevant code.
The error can also be displayed by selecting item 8 “error message” on the main level.
The instrument detects eight causes of error, indicated by the number 1 in the eight-digit code of the
error message. These causes of error can also occur together. The position of the number “1” in the
error message corresponds to a cause, as specified below.

Data transmission interface
The instrument is not powered by the M-Bus interface and is equipped with galvanic isolation. In
a M-bus network with a maximum of 250 instruments, it is possible to perform 24 readouts a day
for each instrument. If fewer readouts are carried out and/or if the number of instruments installed
in the network (connected to the M-Bus system) is lower, any unused requests will be stored in
the instrument to be used when needed.
Note:
• During communication via M-Bus, the selection button cannot be used.
• The M-Bus protocol complies with EN 13757-2, EN 13757-3, EN 1434-3 and M-Bus
recommendation (Version 4.8, November 1997) – protocol IEC 870 parts 1, 2 and 4.
• None of the meters can withstand a voltage greater than that permitted by the bus voltage (±
50 V). Use a level converter/master as an additional protective measure.
• The instruments can be installed in an M-Bus network by authorized and qualified personnel
only.
• Make sure that the structure of the M-Bus network (length and diameter of the cables) is
compatible with the baud rate (2400 Baud) of the connected instruments.
• Recommended cable: telephone cable J-Y (ST) Y2 x 2 x 0,8 mm2.

Safety information
CAUTION:
Failure to follow these instructions may result in personal injury or damage to
property.
The device must be installed, commissioned and serviced by qualified technical
personnel.
Make sure that all connecting fittings are watertight.
Water temperatures higher than 50°C may cause severe burns. When installing,
commissioning and servicing the heat meter, take the necessary precautions so
that these temperatures will not be hazardous for people.
NB: Failure to observe these instructions for proper installation can impair operation and invalidate
warranty.
