3.0 Heating System Design
(continued...)
15mm
Note: Pressure independent balancing and connection sets
are available for this product as an accessory. These valve
kits will maintain the flow in the unit to the required levels.
(See Section 15).
NB: Pipes should be sized using flow rate and pressure losses.
4.0 Unit Selection/Sizing
Heating output performance data is given in the technical data
section of this manual (see page 15). 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.
Please Note:
To utilise the boost outputs, the boiler must have the
sufficient capacity.
Note: It is also possible to electronically remove the highest fan
speed from the functionality of this unit via the control system
(see page 20). 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, i.e. 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 (see Section 15).
When the VIDO is fitted to a stud wall, there may be an adverse
effect on the sound levels especially with the higher fan speeds.
No microbore pipework
Mount on a flat
wall with
sufficient side
clearance.
NO mounting
on uneven wall
surfaces.
