iVECTOR Heater/Cooler
3.0 Heating System Design (continued...)
15mm
Note: Pressure independent balancing and control valve kits
are available for this product as an accessory. These valve
kits 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 (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
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 for
accessories).
When the iVECTOR 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.
