Landys+Gyr ULTRAHEAT T330 Operating And Installation

en Operating and
Installation Instruction
Note: In the text below, the term meter refers both to
the heat meter and to the cooling meter and the com-
bined heat and cooling meter, unless otherwise speci-
fied.
1. General
1.1 Use
The T330 is used as a meter for heating or cooling consump-
tion measurement in systems with water.
The meter consists of a volume measurement unit, two fixed
temperature sensors and an electronic unit that calculates the
energy consumption based on volume and temperature differ-
ence.
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
warranty and calibration validity of the meter will no longer
apply.
•
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 (with-
out 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).
2. Safety informations
The meters may only be used in building service
engineering plants and only for the applications
described.
The local regulations (installation etc.) must be ad-
hered to.
The operating conditions according to the type plate
must be complied with during use. Non-compliance
can result in hazardous situations and the expiry of all
claims arising from liability for defects as well as
liability on the basis of any expressly granted guaran-
tees.
The meter is only suitable for circulating water in
heating systems.
The meter is not suitable for drinking water.
Beware of sharp edges on thread, flange and meas-
uring section.
Requirements for circulating water (CEN/TR 16911:
2016).
Only personnel, trained in the installation and opera-
tion of meters in heating and cooling systems, may
install and remove the meter.

To install the meter proceed as follows:
•
•
•
•
•
•
Subject to change without prior notice
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 sol-
vent.
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 manufac-
turer for appropriate disposal following use. When
shipping please observe legal regulations, in particu-
lar, those governing the labelling and packaging of
hazardous 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
Determine the place of installation in line with the inscrip-
tion on the meter.
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
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.
Fit the temperature sensors in the same circuit as the me-
ter. Please observe admixtures.
Seal the temperature sensor and the fittings to protect
against manipulation.
