(Trend) (AT) Control Models
The information contained in this document provides details of
installation, operation and maintenance for installers and users of
the XBOXER XBC75 & 85 Supply and Extract Ventilation Units with
Heat Recovery.
This supply and extract air handling unit range comprises an
combination of high efficiency centrifugal fans with EC motors, a
counterflow design plate heat exchanger, filters, optional heaters
(LPHW and Electric) and a casing with high mass acoustic treatment.
The one-piece ventilation unit shall be constructed with double
skinned Aluzinc panels on an aluminium Pentapost frame with integral
acoustic mineral fibre ensuring low breakout noise levels. The unit
shall incorporate a high efficiency aluminium counterflow plate heat
exchanger matrix with a thermal efficiency of up to 92%, fitted with
a segmented 100% bypass facility and actuator (patent app. for)
operating under automatic control.
A range of matched, side by side internal and external attenuators
(horizontal units) and double deck internal and external attenuators
(vertical units) with a similar construction method to that of the unit is
available.
General information regarding performance and specifications for the
equipment may be obtained from our Technical Literature, and / or
project specific documentation.

In this product range, several unique concepts have been
implemented with a view to simplifying the installation design.
1. The unit must be installed with at least 650mm clearance from a
wall / barrier. With this absolute minimum clearance, the unit may
be connected to the power supply and control connection.
1000mm clearance is required to remove the LPHW coil and electric
heater.
2. With this clearance, unit filters may be changed, and the fans coils,
heat exchanger and condensate tray may be inspected and cleaned
if necessary.
3. The LPHW and Electrical heater settings, coil bleed and drain, and
all other control adjustments are similarly accessible.
Figure 2. The unit must be installed with at least 650mm clearance from a wall / barrier to gain access from the side. Isolate before removing
panels.
Figure 3. Horizontal unit access and configuration. Standard (left hand) unit shown.
4. Side access, where possible, is preferred in all cases in terms of safe
working access to the equipment under the CDM regulations.
5. Note however, that access in the situation is difficult and additional
time should be allocated. For convenience it is preferred that
wherever possible, this minimum access provision is not adopted,
and it is recommended that a minimum of around 600mm
clearance (as stated in ADF 2010) is allowed.
6. Where these arrangements are not suitable, the Consultant’s
and Contractor’s project specific requirements will always be
accommodated where possible.

11.2 Offloading and Handling from the delivery Vehicle
The weight of the unit modules and palletised items is displayed on
the unit rating plate or on the packaging. Some of the modules have
an ‘uneven’ weight distribution, and this will be indicated by labelling
where appropriate. Ensure that lifting and handling equipment is
adequately rated. Offloading and positioning of the equipment is the
responsibility of the purchaser.
Spreaders should be used when lifting with slings to avoid damage
to the casings. Care must be taken to ensure that slings are correctly
positioned to avoid crushing and twisting of the unit castings.
Where channels and/or support frames are bolted to the underside of
the unit casing, slings or fork-lift arms should be positioned to locate in
the apertures in the channels. If Lifting Eyes have been supplied / fitted
it is recommended that they are used.
CAUTION: The XBC75 & 85 fan units have an uneven weight
distribution, please refer to the unit labelling before Lifting /
offloading the unit.
11.3 Storage
The equipment must be stored in a dry, internal location. Ductwork
connection apertures shall be sealed against the ingress of dust, water
and vermin.
If the storage period is to exceed two months, contact Nuaire for
guidance on the appropriate “mothballing” procedures. Do not stack
units, modules or components.
12.0 Erection and Assembly
Units must be installed in accordance with good industry practice.
These units may only be mounted horizontally and must be fully
levelled in the horizontal plane.
The units are heavy, and should be mounted using suitable methods
of support. The supporting structure must be assessed for structural
suitability.
If these units are being fitted into a ceiling void a suitable support
structure must be provided under each unit, the baseframe provided is
‘NOT’ suitable for this purpose.
Heat recovery components and modules that incorporate cooling
coils may produce condensation during use. An insulated drip tray and
condensate pump is provided. The drain connection must be connected
to a suitable drainage point (see fig. 9. and 18 on page 8 and 15 for
details).
12.1 Condensate Pump Alarm
The condensate pump incorporates an alarm function. If the water
level in the condensate tray exceeds a maximum level (for example, as
a result of the discharge tube becoming blocked or frozen), the alarm
contact will open. This contact is internally connected to the heat
exchanger bypass actuator, and the unit will automatically be placed
into bypass mode, preventing further condensate production. Unit
operation will otherwise be unaffected.
Condensate pump specification
Maximum flow rate = 12 l/h
Maximum head = 20m Vertical, 100m Horizontal
Pipe Connection size (Condensate) XBOXER XBC = 8 mm
LPHW Coils, if fitted, are tested during manufacture to 16 Bar (using
dry compressed air). Coil and valve assemblies are similarly tested to 10
Bar. Operation of standard equipment is rated at PN6, if the intended
system requires higher operating pressures; please contact the Nuaire
Technical department for advice.
Electrical connections to the unit shall be made in accordance with the
appropriate product (see below); and installation wiring diagrams, and
shall use appropriately sized and rated cables.
Only the prepared apertures in the unit casing may be used for cable
entry. Do not drill or cut the unit casing for this purpose. Cable access
points are provided at the ends of the control enclosure.
If the control is rotated to aid connection of cables, please ensure that
sufficient flexibility is provided in the final connection run.
N.B. to avoid conflict with the unit access panels, it is
recommended that electrical and plumbing service connections to
the unit are run at 90 degrees to the main air flow axis.
Control circuit connections must be segregated (i.e. routed separately)
from power connections.
The unit rating label shows the maximum electrical load of the
equipment. Connections to the unit may include single phase supply
connections, and a variety of control circuits.
Only the prepared apertures in the unit casing may be used for cable
entry. Do not drill or cut the unit casing for this purpose.
The equipment must be earthed and earth-bonded. Means of local
isolation for maintenance purposes are generally required (by others).
Ensure that all mains connections are isolated.
Palletised.
Slings via spreaders fitted to unit with base frame.
Figure 13. Lifting
XBOXER XBC unit sections will be delivered to site in one section.
The unit will be labelled with the direction of air flow.
The direction convention must be observed during assembly.
The unit may only be operated in its intended horizontal
installation plane.
The unit must be fully levelled during installation (this is essential to
ensure that condensate drains correctly).
See page 6 and 13 for dimensions and weights.

13.0 Commissioning and Setting to Work
(Note – not all of the components listed here are necessarily
included with the equipment supplied).
13.1 Filters
Remove filter access panels (observe and note airflow direction labels),
inspect filters for contamination with construction debris, replace as
necessary. Replace access panels.
Filter pressure drops will depend on actual flow rate and condition.
Observe and record filter pressure drops after performance
commissioning. Typically, filter “dirty” condition occurs when the initial
filter “clean” readings have been increased by 125Pa.
If filter manometers, pressure switches or indicators have been fitted,
they should be set or adjusted to reflect the commissioned system
operation.
13.2 Heating Coils LPHW
Observe the Flow and Return connection labels on the unit. Drain and
bleed valves are located on the coil (see fig 19). Other valves may be
required in the system pipe-work depending on the installation (by
others).
Where the wet system is at risk of frost damage, the addition of a
proprietary anti-freeze solution to the water is recommended. Note
that any frost protection offered by the unit’s integral control system
will not operate if the power supply to the unit is interrupted.
Ecosmart frost protection is activated on any Ecosmart unit fitted with
LPHW heating, when the outlet air temperature is 4ºC or below. The
unit reacts by shutting down the fan to prevent a ‘wind chill’ effect
reducing the temperature to a point whereby the coil could freeze
and burst. The unit will also drive open the LPHW valve to a fully open
position to allow full water flow through the coil and the main PCB
will close the ‘Heat demand’ contacts. These contacts could be used to
send a signal to activate the boiler and/or valve to open to provide heat
if not already doing so.
Piped connections should be made to the unit using appropriate
techniques, and all pipework must be independently supported. No hot
work is permitted within one metre of the unit.
Ensure that installed pipework runs do not prevent or restrict access to
the unit at any point.
The completed installation (including the connections within the unit,
as these may be disturbed during installation) shall be pressure tested
to the project engineer’s specification (This is a condition of the unit
warranty).
13.3 Electric Heaters
Heater Capacity: XBC75 – 3ph, 12Kw
XBC85 – 3ph, 18Kw
The Electric Heater requires a 3ph supply which is independent from
the main unit supply. Connections to be made through the low level
fixed panel. The Electric Heater may be withdrawn to allow access to
the Heater Controller without the need for wiring to be disconnected
(Ensure the mains supply is isolated before removing any access panels
and any adjustments are made to the Heater Controller).
13.4 Fan Sections
Access to the fan section is via lift off panels (see fig. 1 & 19).
For non-Ecosmart units, wiring to the fan motor / unit terminal box
should be mechanically protected and in made in accordance with the
details on the motor name plate and diagram attached to the unit.
With the unit electrically isolated, rotate the fan impeller / drive
manually, checking that it spins freely.
Check all fixings are secure.
Units must not be operated without all access panels in place – damage
to equipment or injury to personnel may result. Units must not be
operated unless control interlocks are in place – damage to equipment
may result.
Test run motor for condition and correct rotation.
Check that the correct current overloads are fitted and that the current
being drawn does not exceed the motor nameplate value. Excessive
current normally indicates that the ductwork system resistance is
different to design.

CONDENSATE ALARM
The condensate pump incorporates an alarm function.
If the water level in the condensate tray exceeds a maximum level (for example, as a result of the discharge tube becoming blocked
or frozen), the alarm contact will open. This contact is internally connected to the heat exchanger bypass actuator, and the unit will
automatically be placed into bypass mode, preventing further condensate production. Unit operation will otherwise be unaffected.

XBOXER XBC ECOSMART ADAPT (TREND) CONTROL (AT)
14.0 Description of Control - Software Strategy
14.1 Unit Contains The Following Controllable Items:
14.2 Enable Signal
•Inlet damper (if fitted).
•Extract damper (if fitted).
•Heat recovery & bypass damper.
•Heating coil.
•Cooling Coil
•Supply fan speed.
•Extract fan speed.
The unit can be enabled via the following methods:
• Software switch (ENABLE) via SDU, IQView4, IQView8 or network.
• Switched live (230VAC) input, PIR etc.
• Low voltage contact.
• Night cooling / summer free-cooling strategy.
• Scheduled via weekly calendar.
When the enable signal is removed, the unit will run on for a time defined by the
run-on set-point. If an electric heater is fitted, the fans will automatically run-on
for an extra 2 minutes, without heating, in order to dissipate residual heat.
14.3 Occupancy Control
14.4 Boost
14.5 Trickle Mode
When a Trend occupancy sensor is selected via UI4 & 5 software module, the
control will look for a Trend OCC-U sensor in the appropriate input.
An occupied signal will give an enable signal.
0V = Occupied
14V = Unoccupied
When the control receives a boost signal the fans will run at boost speed. Once
the signal is removed the fans will run on for a time defined by the boost run-on
set-point.
When trickle mode is active, the fans will run at their minimum speed even when
there is no enable signal. Heating and cooling will also function in this mode if
available.
14.6 CO Control
14.7 Supply Temperature Control
14.8 Frost Protection
14.9 Night Cooling / Summer Free Cooling
14.10 Alarms
14.10.1 CRITICAL ALARM (LATCHING)
14.10.2 Thermal Trip
14.10.3 Maintenance Alarms (Non-Latching)
When a CO2 sensor is selected via UI4 & 5 function knobs, and an enable signal
is received, ventilation will increase to reduce CO2 concentration the target
CO2 set-point. The target CO2 sensor set-point can be changed as one of the
commissioning set-points.
While an enable signal is present, this mode modulates heating, cooling &
heat exchanger bypass dampers with the aim of the supply air reaching the
temperature set-point. Please note that heating and cooling outputs will only
function if the HeatingType or CoolingType set-points are set to heating or
cooling options.
Should the internal temperature of the unit fall below a value defined in the
commissioning variables, the control will override all heating/cooling logic to
open the LPHW or CW control valves, if fitted. This is to allow any protective
flow through the heating/cooling coils. The supply fan will also stop and the
appropriate frost protection software module will enter an alarm state. This
period will last for a minimum of 5 minutes by default. The fault relay will also
open. Heat and cool demand relays will not operate but digital inputs “Frost
Protecting LPHW” or “Frost protecting CW” will enter an alarm state. Please
note that frost protection will only function if the HeatingType or CoolingType
set-points are set to LPHW or CW.
Once enabled in software, this routine uses an individual time schedule to cool
the fabric of the building at night using only the external air. This mode only
functions if the daytime temperature is above the set-point, cooling is possible
and if the cooling air is not too cold.
Once in critical alarm state the unit will drive all heating and cooling outputs
to 0V. Other functions continue as normal. The critical alarm is latched and
required manual reset to clear.
In case of software failure, as a final resort, the electric heater is protected by a
fail-safe thermal overload switch. This switch disables the heater controller once
the temperature reaches 80°C. When this occurs, the critical alarm will latch in
software.
Once the unit cools, the contactor will re-engage but the heater signal will
remain at 0V until the critical fault is reset in software or by power cycle.
Once in maintenance alarm state the only action taken is de-energising of the
fault relay. Once the trigger is removed, the alarm will reset automatically.
Causes of critical alarm:
• Fan fail via alarm circuit 1.
• Heater overtemp via alarm circuit 1.
Causes of maintenance alarm:
•Condensate pump fault via alarm circuit 2 (This bypasses the heater
exchanger automatically).
•Sensor failure.
•Low supply temperature, default 8°C.
•Frost protection routine active, default 4°C (Only runs if water valves are
selected as fitted).
•Excessively high supply temperature reading (this will stop heating).
•Filter fault
All alarms have a hold off period set by the set-point “Alarm delay”.
The system incorporates a web enabled Trend IQ422/12/LAN/BAC/230
controller.
