2.2 Operating principle
Fig.1. Halton Max Ultra Circular (MUC) has two ultrasound sensors for airflow measurement.
The damper can function either as a supply or an exhaust unit. It maintains the required airflow
through ultrasound measurement, regardless of variations in the room conditions or duct pressure.
The damper has an airflow controller, two ultrasound sensors for airflow measurement, and an
actuator for controlling the damper blade.
The airflow controller can be controlled via:
•Modbus RTU,
•the control panel,
•an analogue signal.
All three control modes are synchronized between each other. The airflow measurement includes
temperature and duct type connection compensations, providing accurate and reliable airflow
measurements even at small safety distances.
Room conditions can be adjusted
•manually from an end-user interface

Halton Max Ultra Circular (MUC) - Installation, commissioning and maintenance guide 8(31)
Version 1.0 All rights reserved © Halton
•by different sensors such as occupancy or room pressure sensors, thermostats or timers
•remotely from a building management system (BMS)
The airflow setpoint can be modified between the minimum and maximum settings from the room
controller interface or a BMS.

3 Installation
3.1 Before you start
3.1.1 Installation process
The installation is carried out by Halton Field Service or an approved partner.
Follow the installation process chart to install the Halton Max Ultra Circular (MUC) damper.
Fig.2. Halton Max Ultra Circular (MUC) installation process chart
3.1.2 Installation information
Installation options
There are three possibilities to position the damper. Sensors can be directed outwards, side or
inwards.
Safety distances and accuracy
Disturbances in the ductwork such as duct bends, T-branches and sound attenuators cause
turbulence and an uneven airflow. This can lead to fluctuation and inaccuracy in measurement
values.
NOTE: The recommended safety distance is greater or equal to one duct diameter distance, to
ensure the optimal accuracy.
Halton Max Ultra Circular (MUC) technical performance:
•Velocity range 0,5 — 10,0 m/s

Halton Max Ultra Circular (MUC) - Installation, commissioning and maintenance guide 10(31)
Version 1.0 All rights reserved © Halton
•General Measurement Uncertainty
Accuracy ±5 %
Minimum Safety distance 1D
•Expected Measurement Uncertainty, when correct installation parameter is applied
± % or l/s depending, which is the greatest of the percentage or the absolute value for the
specific product size.
Dim. 100 = ±5 % or ±1,00 l/s
Dim. 125 = ±5 % or ±1,25 l/s
Dim. 160 = ±5 % or ±2,5 l/s
Dim. 200 = ±5 % or ±4,0 l/s
Dim. 250 = ±5 % or ±6,5 l/s
Dim. 315 = ±10 % or ±10 l/s
NOTE : The measurement uncertainty is defined in laboratory conditions and may be greater in
practical installations, where non-optimal installation situations or multiple consequent disturbances
may exist.
Fig.3. Minimum safety distances
If the straight duct between the damper and disturbance is less than five times the duct diameter
distance, then the installation factor needs to be added to the airflow controller during
commissioning.
NOTE: The installation factors can be found in the 6.2.Installation parameters chapter.
Wiring and controller connections
The wiring must be carried out by professional technicians following local regulations. For the power
supply, a safety-isolating transformer must be used.

3.2 Step by step instructions
3.2.1 Connecting the damper to the ductwork
Before you start
•Check the inside of the damper for damage and loose parts.
•Remove any contamination from the ductwork.
•Support the installation with a suitable suspension system. Load suspension systems only
with the weight of the unit. Adjacent components and connecting ducts must be supported
separately.
•Wear protective gloves.
CAUTION!
Risk of personal injury or material damage.
Procedure
Position the damper so that the display is visible.
NOTE: See safety distance in installation information chapter.
There are three possible positions of the damper:
oOutwards oSide
