3. CONNECTION OF EXTERNAL FUNCTIONS
3.1 General
Cables from external functions are connected to
connection boxes on the control card.
Knockout openings for screw caps are located in the
control enclosure.
Functions:
External stop of unit (external disconnection)
External Fire/Smoke (external disconnection)
External alteration High/Low speed
(external connection/disconnection)
Set value shifting (external 0 – 10 VDC)
Flow indication FL/alt. stepless controlling of
cooling unit (output 0 – 10 VDC)
Flow indication TL (output 0 – 10 VDC)
Summary alarm A (free making contact)
Summary alarm B (free making contact)
Controlling of cooling unit on/off (free
making contact
Unit in operation (free making contact)
3.2 External stop
If the connection between connections 1–2 is broken the
unit is unconditionally stopped. "Stop" is shown in the
display. The unit is started when the connection closes.
Clamp is factory mounted.
3.3 External Fire/Smoke
If the connection between connections 3–4 is cut the unit
is unconditionally stopped and the alarm text "External
Fire alarm released" is shown in the display. Alarm light
and summary alarm relay A-alarm are activated. The error
must be repaired and the alarm reset on the display
before starting. Clamp is factory mounted.
3.4 External alteration Low/high speed
On connection 5–6 device for alteration between low and
high speed can be connected. It might be presence
sensor, overtime timer, overtime pushbutton, air quality
sensor, hygrostat or other potential free contact function.
Use the display to choose if high speed is required with
closed or broken contact. Delay of resetting to low speed
after contact alteration is programmed with the display,
0.00–3.59 in hours and minutes.
The internal high speed of the time switch is placed
above external contact function. If for instance presence
sensor is used the internal time switch shall be programmed to low speed all the time.
3.5 External set value displacement
Connections 7(-) and 8(+) is input for 0–10 VDC for
displacement of set value. Upon regulation of supply/
exhaust air, the set value for supply/exhaust air
temperature is displaced. Upon regulation of ERS, the
difference between EA/SA is displaced.
The function is activated in the display. The influence is
+/- 5°C according to 8.4.
3.6 Flow indication Supply–Exhaust air
On connections 9(+) and 10(-) there is a output voltage of
0 –10 VDC which is proportional to measured supply air
flow. Connections 11(+) and 12(-) contains 0 – 10 VDC for
exhaust air flow.
3.7 Summary alarm outputs
Connections 13–14 summary alarm B free making
contact (10 A), closed at alarm.
Connections 15–16 summary alarm A free making
contact (10 A), closed at alarm.
3.8 Cooling unit
3.8.1 On/off control
Connections 17–18 free making contact (10 A) for ON/
OFF controlling of possible cooling. The function is
activated in the display.
When need for cooling the contact closes. A neutral zone
of 2°C is programmed. When the need for cooling stops
a restart time of 10 minutes starts, which must end
before the contact can close again. This time delay is to
prevent the unit from starting and stopping too often.
3.8.2 Stepless control
Controlling can also be carried out stepless, depending of
the need of cooling via 10 VDC. Connections 11(+) and
12(-), which normally are for indication of exhaust air
flow, is then used. Due to this, indication of exhaust air
flow can not be obtained.
When using the valve adjuster, 24V supply must be
taken from an external source.
3.9 Operation indication
Connection 19–20 free making contact(10 A). The
contact is closed when the unit is in operation (low/high
speed). The contact is broken when unit is stopped,
regardless to if it has been stopped manually, via clock or
alarm.
3.10 UTG 230 V
Connections L, , N marked with UTG 230 V is a
connection with 230 VAC supply, which is cut off with the
main switch.
The socket lays on the supply fuse and therefore the
maximum load is depending on how hard the unit is
driven.
The outlet is recommended for use for control voltage or
for damper motors.

shown in the next sketch), since the switching clock
handles alteration from High to Low speed.
The second line shows which operating mode is
current: HIGH SPEED, LOW SPEED, or STOP. If any
other function is affecting the flow, it flashes on the
second line alternately with current mode, e.g., FILTER
TEST, SUMMER NIGHT COOL, ZERO SET CALIBR.,
ROTARY GUARD TEST, RECOOLING, or COOL
RECOVERY.
At "MANUAL OPER" button "H–LS is used in order to alter
between manual high speed or manual low speed.
In "MANUAL OPER" there is no automatic switch
between high and low speed via switching clock.

7.4.1 ERS regulation
Exhaust air temperature Related Supply air regulation
(ERS). This means that the supply air temperature is
regulated in relation to the exhaust air temperature.
GOLD is intended mainly for this type of regulation.
Choose step 1, 2 or 3 according to diagram to the right.
OFF/ON–DIFF is the difference which the supply air
temperature shall be below the exhaust air temperature
below the break point in the diagram to the right. The
diagram is drawn for 3°C DIFF.
The BREAK POINT is the point in the diagram from where
the steps starts. It is defined from the exhaust air
temperature. In the diagram, the breakpoint is 22°C.
7.4.2 Other regulation types

When PROG is pushed, the different values will flash.
They are then possible to alter with button 1 and 2, which
then shows + or - in the display.
7.4.2.1 Exhaust air regulation
EXHAUST AIR TEMP is the desired temperature in the
exhaust air duct.
SA – MIN is the lowest temperature and SA – MAX is the
highest temperature allowed for supply air when the
regulation tries to keep exhaust air constant.

Closed Opened
7.6. Throttle damper
Before the throttle damper is adjusted, duct calibration
shall be carried out, see 8.6.
The damper shall be fullyopened, pushed so that no part
is in the the exhaust air inlet (see sketch).
Set the supply and exhaust air flows on the display
(according to 7.5 above).
After that, make an adjustment which distributes the
total supply and exhaust air flow so that each diffusor
obtains the correct flow.
There after it is time to adjust the pressure balance in the
unit with the help of the damper so that the purging flow
goes to the exhaust air side.
On the external electrical enclosure there are two red
pressure nipples for measuring the negative pressure on
the supply and exhaust air side. At the nipples there are
a + for the pressure on the supply air side and a - for the
pressure on the exhaust air side.
Connect the manometer or other pressure meter to the
connections for + and - and measure both pressures.
NOTE! With both nipples negative pressures are
measured.
If the negative pressure on the exhaust air side is at least
as high as on supply air, the adjustment is ready.
If not, remove the inspection door, adjust the damper
slightly, put back the inspection door and measure the
pressures. Repeat until the negative pressure on the
exhaust air side is at least as high as on supply air side (0–
20 Pa).
New duct calibration should be done when the damper
has been adjusted.
WARNING!
Inspection hatches located on the pressure side behind
the fan must not be opened when the fan is operating.
The hatch can open suddenly and cause personal
injury.

8.4 Set value displacement
At SET VALUE DISPL = 1 (on). The temperature set value
can be displaced +/- 5°C with the help of 0–10 VDC
external control.
The set value displaced is the EA/SA-differance at ERSregulation, the supply air temperature at supply air
regulation and the exhaust air temperature at exhaust air
regulation.
When activating the function the set value is displaced
according to diagram to the right. 0 VDC gives a decrease
of the temperature set value of 5°C, 5VDC gives
unchanged set value and 10 VDC gives an increase of
5°C. Upon ERS regulation, the EA/SA difference decreases when there is an increased control signal. EA/SADIFF cannot be less than 1° C.
The external control signal is connected on the
connection box 7–8 (-)(+) of the control card.
8.5 Cooling unit
8.5.1 Cooling on/off
At COOLING UNIT = 1 (on).
When need of cooling occurs a closure of free making
contact is obtained (connection box 17–18). This closure
can be used to start an external cooling unit.
When the need of cooling stops the contact opens and a
restart time of 10 minutes starts running. This is to
prevent too many start/stops of the cooling unit
A neutral zone of 2°C is programmed so that set value at
cooling is 2°C higher than set value.
Conditions for activation of cooling function.
Exhaust Air regulation:
- Exhaust air temperature rises above the set value
including the neutral zone.
- Supply air temperature is above the set value on
SA-MIN.
ERS Regulation, Step 3:
- Supply air temperature rises above the set value
according to the set curve including the neutral
zone.
Conditions for interrupting the cooling function:
Exhaust Air regulation:
- Exhaust air temperature has gone down to 0.5
degrees above the set value.
- Supply air temperature is below the set value on
SA-MIN.
ERS Regulation, Step 3:
- Supply air temperature has gone done to 0.5
degrees above the set value according to the set
curve.
The function is not applicable upon Supply Air
regulation and ERS Regulation, Steps 1 and 2.

8.5.2 Stepless Regulation of Cooling
At COOL AGGREGATE = 2, a control signal of 0 - 10V
DC is maintained on plinth 11 (+) and 12 (-) for
regulation of stepless cooling. (See 3.8.2)
A neutral zone of 2° C. is allowed, as above.
When cooling is needed, the control signal is regulated
steplessly so that the set value increases while the
neutral zone is maintained.
SA-MIN maintains temperature limits for Supply Air
upon Exhaust Air regulation.
A closed contact between plinths 17 and 18 is also
maintained with this function when cooling is needed
and the temperature rises above the set value
including the neutral zone.
When the temperature has gone down to 0.5 degrees
above the set value, the contact opens and a restart
time of 10 minutes begins to run.
The contact also opens when SA-MIN goes below the
set value upon Exhaust Air regulation.
8.6 Duct calibration
At DUCT CALIBR = 1 (on).
The unit is operating on a firm calibration flow and
measures where in the flow diagram the unit is operating
with care taken to connected duct system and with clean
filters.
Duct calibration shall always be carried out when
alterations in the duct system have been carried out.
Set the duct calibration to 1 and go to "main menu" Auto
oper or Manual oper.
Duct calibration is carried out and 1 automatically
changes to 0 when the unit has stored the calibration
value and returned to normal operation (after appr. 5 min).
8.7 Service period
Shows how many months remaining until service period
alarm is released. The programming is carried out in
months.
Resetting of alarm is carried out via programming SERV
PERIOD to the next service interval.

8.8 External high speed (time delay)
The function gives time delayed reset to low speed when
the input for external alteration between High speed and
Low speed shifts.
The time can be set 0:00 – 3:59 which is the time in hours
and minutes. 0:00 gives that the function is not activated.
Use: for instance prolonged operation with button or reoperation time together with presence sensor.
8.9 Closure = High speed or Low speed
Here can be chosen if the external alteration HS/LS shall
give High speed or Low speed at closed contact. Closure
= Low speed shall be chosen at i e presence sensor. If the
contact is not used "Closure = High speed" shall be
chosen (factory set).
The external contact only influences when the internal
switching clock calls for Low speed.
8.10 Time filter test
Set the start time for filter test (0.00–22.59). It shall be set
on the time when the least inconvenience for the user is
at hand, as the unit both is stopped and operates on filter
test flow regardless to what flow is chosen. Factory set
value is 22.59.
While External Stop is activated, no filter tests are
done. The filter test can be done if the aggregate is
running at low or high speed. Low speed can be set to
0 l/s, i.e. shut-off but still active. The filter test cannot
be done on a manually stopped aggregate.
8.11 Filter test
At filter test, the unit is operated up to filter test flow and
one of the pictures to the right is shown. The flow is
stabilized after ca 1 minute.
FILTER STATUS NOW shows the degree of pollutions for
each filter and ALARM LIMIT shows what level of
pollutions that provides a filter alarm. 10 units
corresponds to recommended final pressure drop across
the filter.
The limit can be set between 0 and 99. The factory set
value is 10. This causes the rpm of the fan to increase
approx. 5% from clean filter until alarm is shown.
8.12 Anti-freeze guard function
When water coil with anti freeze guard function is
connected it is determined if the anti freeze guard
function with heating of the water coil shall be activated
or not (activated = 1). The function is keeping coil warm
to 12°C at operation and to 25°C at stopped unit.
If the function is chosen and no sensor is connected, an
alarm is obtained.

11. MAINTENANCE
11.1 Filter replacement
When filter alarm has activated, filter shall be replaced.
Release the expander locking and withdraw the filters
straight from the unit. The filters are of disposable type
and shall be replaced with new filters.
Lock the new filter on its' place with the expander handle.
This is important in order to achieve complete sealing.
Duct calibration shall always be carried out when
replacing filter.
11.2 CLEANING
11.2.1 General
Internal cleaning of the unit is carried out when
necessary. Checks should be carried out in connection to
filter replacement or at least twice/year.
WARNING!
Inspection hatches located on the pressure side behind
the fan must not be opened while the fan is operating.
The hatch can open suddenly and cause personal
injury.
11.2.2 Heat exchanger
The rotor is easily accessible from all sides which makes
inspection and cleaning easy.
The rotor is mainly cleaned with vacuum cleaner with a
soft nozzle so that the air ducts of the rotor are not
damaged.
When taking out rotor.
Mechanically:
The suspension consists of screw–distance–shaft–
distance–screw. One of the distances is tooled in a way
that enables a grip around the shaft if the screw jams. The
rotor is withdrawn with the shaft in position.
After cleaning the rotor is dried off with pressured air.
Detergent must not be corrosive to aluminium!
After cleaning check that the drive belt runs correctly
around the motor pulley and heat exchanger.
11.2.3 Fans
On Size 1, the fan brackets are attached with 2 locking
knobs and the flexible web hose with 1 locking knob.
On Sizes 2 and 3, the fan assembly is attached with 2
locking knobs. The flexible web hose is attached over the
collar, using a clamp belt with off-centre lock.
All locking wheels must be loosened before disassembly.
Also the contacts the cables are loosenened before the
fans are withdrawn.
The fans are vacuum cleaned. Remove possible dirt on
the fan blades. Check that the impellers are balanced.
The fan motor is vacuum cleaned or brushed. It can
also be gently cleaned with a wet rag and detergent.
When mounting the fans for Sizes 1 and 2, make sure
that the flexible web hose has a good seal against the
aggregate side.
When mounting the fans for Sizes 2 and 3, make sure
that the flexible web hose and the clamp band are
securely clamped over the collar so that the connection
is tight.
11.2.4 Coils (accessory)
Installation of coils shall be carried out in a way that
enables inspection and cleaning.
Check necessity of cleaning at least twice per year.
Cleaning is only allowed by pressured air towards
ordinary air direction, vacuum cleaning with a soft
nozzle or wet cleaning with water and/or detergent.
If detergent is used it must not be corrosive to aluminium or copper.
Before cleaning starts nearby duct shall be protected.
In connection to cleaning check in applicable cases
venting.
Electrically:
The contact of the heat exchanger motor is disconnected.
The screws in the rubber A/V:s are loosened and then the
motor is removed.
The electric box is loosened with four screws on the
outside of the exchanger, then it is pushed
sideways. The electric box is not withdrawn from the
unit but folded out from the unit and cables are placed
in the socket on the heat exchanger gable.
When heavily dirtied cleaning with pressured air can be
carried out. It is also possible to use detergent, if the rotor
is withdrawn from unit.
