• Two self-adhesive labels for configuration changes (see user guide at www.epluse.com/relabeling)
• Test report according to DIN EN10204 - 2.2
CAUTION
• Accurate measurement results are conditioned by the correct positioning of the sensing probe in the air stream. Best accuracy
is achieved in laminar flow.
• Observe the minimum inlet and outlet path length, see page 5.
• Avoid mechanical stress onto the probe and mainly onto the sensing head.
• Observe the humidity working range 5…95% RH, non-condensing.
• Avoid installation in corrosive environment, as this may lead to sensor destruction.

Hardware
The bus termination shall be realized with the 120 Ohm resistor on board, slide switch S2.
Very important:
For proper function the power supply must be strong enough to ensure supply voltage within the specified range (see technical data)
at any time and at all devices in the bus. This is particularly relevant when using long and thin cables which can cause high voltage
drop; please note that a single EE660 requires peak current of 150 mA.
Address Setting
Address Switch
Address Switch
Address setting via EE-PCS Product Conguration Software:
All DIP switches at position 0 → address has to be set via PCS
Example: Slave address is set via conguration software.
Address setting via DIP switch:
Modbus (Slave device): Setting the DIP switches to any other address than 0, overrules the slave
address set via configuration software (permitted values: 1…247).
1
BACnet (Master device): Setting the DIP switches to any other address than 0, overrules the slave
address set via configuration software.
BACnet Note: permitted values are 0…127.
The 8th bit of the DIP switches is ignored (ID 127 = 0111 111).
To set address 0 via DIP switches, the 8th bit shall be set to 1 (ID 0 = 1000 0000).
Example: Slave address set to 11 (= 0000 1011 binary).

CONFIGURATION AND ADJUSTMENT
The EE660 as ordered is ready for use immediately and requires no configuration by the user. If required, the optional USB
configuration adapter and the E+E Product Configuration Software (EE-PCS) can be used for changing the factory setup as
well as for adjusting of the air velocity measurement.
Note: The EE660 must not have any additional power supply when using the USB configuration adapter HA011066.

POSITIONING OF AIR VELOCITY SENSOR IN A VENTILATION DUCT
The reliable and accurate measurement of air velocity depends on the correct positioning of the sensor in the ventilation duct.
Accurate measurements are only possible if the air velocity probe is positioned at a location with a laminar (not-turbulent) flow.
The required length of the calming section after a fault is a function of the tube diameter D. For a rectangular channel a x b applies:
INCORRECT CORRECT
Mounting the sensing probe in the middle of the
channel.
The optimal position is after the filter.
Please note sufficient distance.

MAINTENANCE OF THE E+E AIR VELOCITY TRANSMITTERS
Due to the absence of moving parts, the E+E air velocity transmitters are not subject to wear. The construction (shape, dimensions
and materials) of the hot film air velocity sensor is per se highly insensitive to dust and dirt. No maintenance is required under
normal environmental conditions. For operation in polluted environment it is advisable to periodically clean the sensing head by
washing it in isopropyl alcohol, preferably in an ultrasound cleaner. Alternatively shake it gently few minutes in a pot with isopropyl
alcohol and let it dry free. Do not touch or rub the sensor and do not use any mechanical tools for cleaning.
