Note:
A pressure independent balancing and control valve is
available for this product as an accessory. This valve can simplify
system design by eliminating the possible need for larger
balancing valves elsewhere in the system, and will maintain the
flow in the unit to the required levels. See accessories section
for more details.

4.0 Unit Selection/Sizing
Heat output performance data is given in the technical data
section of this manual (see page 12). Outputs are shown for the
three fan speeds, however, it is important to size the unit to
match the calculated heat loss requirements of the room with
the unit operating on the
normal fan speed
. The higher fan
speeds are used in Comfort mode when the room temperature
is significantly lower than the preset temperature.
Note:
It is also possible to electronically remove the highest fan
speed from the functionality of this unit via the control system
(see page 16). This may be advantageous on low temperature
systems to prevent cool air being blown into the room on the
highest setting.
When establishing the temperature difference, ie mean water to
room temperature difference, allowance should be made for the
temperature drop in the system. It is the water temperature at
the unit that dictates the output.
5.0 Location
This unit may be fitted to any convenient wall at a height from
the floor level that suits the application, providing an unimpeded
flow of air into the area to be heated/cooled.
For cooling applications, the need for disposal of condensate
may influence the position of the unit.
Mount on a
flat wall with
sufficient side
clearance.
NO mounting
on uneven wall
surfaces
NO mounting
on stud walling
No microbore pipework
