Installation Instructions for the
TBLZ-1-31-1 and TBLZ-1-31-2 Humidity sensor
GOLD
1. General
The humidity sensor is used in ventilation systems in which
the aim is to measure and/or regulate the air humidity.
Description
The humidity sensor contains a humidity sensing element,
which also measures the temperature.
The humidity sensor is supplied with a 7 m long cable for
bus communication and is connected with a modular con-
nector.
The communication cable is used for supplying power and
signal transfer.
The sensor is mounted on a ventilation duct by means of
the duct connection flange supplied.
Function
Humidity and temperature values are transmitted via
Modbus communication to the control circuit card of the
air handling unit.
The humidity sensors are coded for supply air and extract
air respectively.
The TBLZ-1-31-1 is designed for installation in the supply
air and is used for the dehumidification or humidification
function.
The TBLZ-1-31-2 is designed for installation in the extract
air and is used for the dew-point regulation function with
cooling beams or the humidification function.
2. Installation
Mount the humidity sensor in the supply or extract air
duct.
The position in which the humidity sensor is mounted will
no affect its performance but it is inappropriate to mount
it standing with its connection pointing downwards
because this may lead to moisture collecting inside the
sensor.
It is important that the sensor be mounted with its sensing
element (in the tip of the sensor) positioned in the centre
of the duct.

4. Electrical Connections
Run the electrical cable of the humidity sensor through the
junction hood of the air handling unit to the control circuit
card.
The humidity sensor should be connected to the internal
communication bus.
The optional connections are circled in the figures to the
right.
