Landis & Gyr ULTRAHEAT T230 Operating And Installation Instruction

en Operating and
Installation Instruction
Note: In the following text, the term meter refers to both
the heat meter and the cooling meter unless they are
otherwise differentiated.
1. General
1.1 Use
The T230 is used as a meter for heating or cooling consump-
tion measurement in systems with water.
The meter consists of a high-tech plastic volume measurement
unit, two temperature sensors connected in a fixed position and
an electronic unit that calculates the energy consumption from
the volume and temperature difference.
The meter combines modern microcomputer technology with
innovative ultrasonic measuring technology for which no me-
chanically moving parts are necessary.
This technology is thus wear free, robust and largely mainte-
nance free. High precision and long-term stability guarantee
precise and equitable cost accounts.
Note: The meter cannot be opened without damaging
the security seal.
1.2 General notes
The meter left the factory in a faultless condition where safety
is concerned. The manufacturer will provide additional tech-
nical support on request. Calibration relevant security seals on
the meter must not be damaged or removed. Otherwise the
guarantee and calibration validity of the meter will lapse.

Keep the packaging so that you can transport the meter in
its original packaging following expiry of the calibration va-
lidity.

Lay all cables at a minimum distance of 500 mm to high
voltage and high frequency cables.

A relative humidity of < 93% at 25 °C is permissible (without
condensation).

Avoid cavitation in the whole system due to overpressure
i.e. at least 1 bar at qp and approx. 2 bar at qs (applies for
approx. 80 °C).

Safety Information

The meters may only be used in building service
engineering plants and only for the applications de-
scribed.
The local regulations (installation etc.) must be ad-
hered to.
Adhere to the operating conditions according to the
dial plate during use. Non-adherence can cause haz-
ards and the guarantee will lapse.
Do not under any circumstances carrying out welding,
drilling or soldering work close to the meter.
The meter is only suitable for circulating water in
heating systems.
The meter is not suitable for drinking water.
Adhere to the AGFW requirements regarding circulat-
ing water (FW510).

To install the meter proceed as follows:

Determine the place of installation in line with the inscrip-
tion on the meter.

Observe the dimensions of the meter and check whether
there is sufficient space available.

Rinse the system thoroughly before installing the meter.

Fit the meter vertically or horizontally between two slide
valves so that the arrow on the housing and the flow direc-
tion match. Also observe the installation situations and the
following examples of installation.
Subject to change without prior notice
Only personnel, trained in the installation and opera-
tion of meters in heating and cooling systems, may
install and remove the meter.
Only install or remove the meter when the pipes are
pressure-less.
After installing the meter, check the leak-tightness of
the system.
Guarantee and calibration validity will lapse if the
calibration relevant security seal is broken.
Only clean the meter from outside with a soft, lightly
wetted cloth. Do not use any spirit or cleaning solvent.
As far as disposal is concerned, the meter is a waste
electronic appliance in the sense of European Di-
rective 2012/19/EU (WEEE) and it must not be dis-
posed of as domestic waste. The relevant national,
legal regulations must be observed as the appliance
must be disposed of via the channels provided for this
purpose. The local and currently valid legislation must
be observed.
The meter contains lithium batteries. Do not dispose of
the meter and the batteries with domestic waste.
Observe the local stipulations and laws on disposal.
You can return the lithium batteries to the manufactur-
er for appropriate disposal following use. When ship-
ping please observe legal regulations, in particular,
those governing the labelling and packaging of haz-
ardous goods.
Do not open the batteries. Do not bring batteries into
contact with water or expose to temperatures above
80 °C.
The meter does not have any lightning protection.
Ensure lightning protection via the in-house installa-
tion.
Installation
Note: At a heating meter the mounting place of the
flow sensor cold side is equivalent to return
The mounting place of the flow sensor hot side is
equivalent to flow .
Note: At a cooling meter the mounting place of the
flow sensor hot side is equivalent to the return
The mounting place of the flow sensor cold side is
equivalent to flow .
Note: Only use the rubber EPDM flat seals that are
supplied.
