ECONET®SCOPE OF DELIVERY
Heat exchanger:
The ECONET®heat exchangers consist of a finned coil in the
supply air unit and in the exhaust air unit with functions for
heat/cooling recovery, heating as well as cooling of the supply
air. The coils are equipped with drip trays and connections
for air purging and drainage. A droplet eliminator should be
chosen if the air velocity through the coil is high. The coils are
manufactured from copper tube, which is expanded against
aluminium fins. The header consists of either copper or rust-
protected steel. The maximum operating pressure of the coils
is 1.5 MPa, and the test pressure is 2 MPa.
Other material for the tubes, fins and the framework can be
specified in the Acorn selection program.
Coils with hygiene fins should be specified if cleanability
of the coils according to standards VD13803 and VD16022 is
required.
The supply and exhaust air coils are connected together
by a liquid circuit with the possibility to connect externally
supplied energy or heating/cooling. (EQRZ-05 ECONET®
Exchanger Package, see separate manual).

ECONET®ASSEMBLY AND INSTALLATION
GENERAL ADVICE
Failure to observe general advice and installation requirements
can lead to the risk of damage.
Flushing the pipe system:
– ECONET®pump units are cleaned and flushed at the factory.
When flushing the remainder of the system, we recommend
that the pump unit is disconnected and that the P40 pump is
not used during flushing.
It is extremely important to remove all the flushing/cleaning
fluid from the system before filling with antifreeze as a
chemical reaction can occur between the cleaning and anti-
freeze liquids. As the coils cannot be emptied completely,
they must not be exposed to the cold without anti-freeze
recovery.
Filling:
– For optimal heat recovery, we recommend an approximate
25-35% ethylene glycol mixture. Max mixture for the pump
is a 40% ethylene glycol mixture. The P40 pump should not
be used when filling the system.
Use a separate filling system, e.g. a separate pump with a
non-return valve for filling the system, e.g. a hand pump.
– Fill until a static pressure of 1-1.5 bar is obtained on the
suction side of the pump to avoid the risk of pump cavitation.
– Uses premixed anti-freeze liquid, type ethylene glycol/ water
mixture. Prevent exposure to oxygen. When using concen-
trated ethylene glycol, it must be mixed with distilled water.
The liquid must be mixed 24 hours in advance, so that the
mixture will be free of micro bubbles. When filling with pre-
mixed liquid from a tanker lorry, ask for a flushing certificate.
– Mark the system with a label showing the actual flow, type
of anti-freeze liquid, and concentration.
– Check for, and seal any leaks.
– Check that the anti-freeze liquid used has sufficient protec-
tion against corrosion, anti fouling and biological growth.
Follow the instructions of the anti-freeze liquid manufacturer
Air purging:
To get rid of all air in the system takes time, but is vital for the
performance. Use automatic air purge valves combined with
manual air purge valves. Prevent the risk of contamination
blocking the sealing and jeopardizing the shut-off function of
the automatic air purge valve. Install a filter if there is a conti-
nuous problem with contamination. When the system is free of
all air, make sure that all automatic air eliminators are OK and
all manual valves are closed.
Open and close all valves a couple of times. Start the Econet®
pump. The pump should be run manually via the frequency
inverter at maximum 30 Hz.
Under no circumstances must the pump be allowed to run
dry, due to the risk of damage to the seals. Purge the air from
the pump with its own purging valve. Make sure that the system
pressure is maintained at 1–1.5 bar. Refill the system con-tinu-
ously as the pressure decreases. If the pressure drops below
0.5 bar, there will be an A-type alarm from the controller.
Miscellaneous:
– Under no circumstances may the P40 pump be run dry.
This is because the pump will be damaged by the air,
resulting in leakage.
– The coils in the AHU have to be installed with separate shut-
off valves. The total pressure drop for the heat exchangers
on the secondary side must not exceed 40 kPa at the maxi-
mum liquid flow for a closed heat recovery circuit, in the
case of a higher pressure drop in the exchangers then it
should be taken into account when dimensioning the system.
The purging, safety valve and drain connections must be
routed to the connection vessel next to the unit.
– Use air purge valves that can handle micro bubbles (type
Spirovent or Flamcovent).
– The vessel must be installed on the suction side of the pump
(between the pump and the plate heat exchangers for supple-
mentary energy) with a volume of at least 5 % of the total
system volume and with 1.0 bar pre-pressure, 4.5 bar opening
pressure.
– If the risk of cavitation is present on the suction side of the
pump, it is advisible to install underpressure air eliminators.
The purging, safety valve and drain connections are
routed to the connection vessel next to the unit.

MAINTENANCE INTRUCTIONS
GENERAL MAINTENANCE INSTRUCTIONS
The ECONET®unit does not require regular maintenance, other
than observing the maintenance instructions provided by the
anti-freeze liquid manufacturer. On the other hand, we recom-
mend that regular performance checks are carried out to ensure
that the unit operates as it should.
Check and pay special attention to the following:
– abnormal noise and vibrations, if any
- corrosion on piping and brazed pipe joints, if any
- loose pipe clamps, if any
CLEANING THE STANDARD ECONET® COILS
Even an effective air filter cannot remove all the dust from the
air. The coating of dust on heating surfaces obstructs the air
flow and gives poorer heat transfer. The coils must be kept
clean, which is best performed with one of the following alter-
natives or combinations of these.
1. Blowing clean with compressed air.
2. Blowing clean with steam
3. Washing or rinsing with water.
In the case of heating surfaces that
are coated with grease, an appropriate
detergent should be added.
4. Vacuum cleaning. After cleaning,
all the fallen dust should be removed
before starting the fan.
The drip trays for the coils should be cleaned as appropriate.
Also ensure thet the water trap is cleaned and filled with water.
CLEANABLE COILS FOR HYGIENE APPLICATIONS
All ECONET®coils with hygiene fins are fully cleanable accor-
ding to the standards VDI3803 and VDI6022. This means that
the coil can be cleaned with a high-pressure water system
right through the core. The cleaning nozzle used for coils with
a fin pitch of 2.0-2.5 mm and deeper than six tubes is THD
Power Clean manufactured by TECHNISCHER HYGIENE DIENST
GMBH (E-mail: [email protected], web: www.thd.info). If the coil is
six tubes deep or less, an ordinary nozzle can be used.
1. Make sure that no sensitive
equipment, either inside or outside
the unit, can be harmed by
the water. Be extra careful not to
damage the filter. If the unit has
an empty section (EQTC), use
the special drip plate to protect
the rest of the unit.
2. Clean the coil with a high-pressure cleaner. If the coil is
deeper than six tubes, a THD Power Clean is needed to
ensure a full cleanability.
3. Point the nozzle at a 45-degree angle to have a free passage
for the water jet through the coil. Make sure that the water
penetrates the coil.
4. Remove all dirt.
5. Dry all surrounding parts in the unit.
ANTI-FREEZE LIQUID
Follow the instructions from the anti-freeze liquid manufacturer
regarding controls, maintenance, flushing and intervals for filling
with fresh liquid, etc.
Warning!
Avoid flushing with water near the electrical
connections of the inverter and cabinet, since
water could then seep into them and may
cause a short circuit.
TASK INTERVAL, EACH YEAR
Liquid status Check the freezing point of the frost protection fluid and follow the instructions from the anti-freeze liquid
manufacturer, controls of frost protection/quality, purity, colour, etc.
Check the system pressure and top up with ethylene glycol mixture if necessary.
Check the liquid flow against the balancing report.
Coils Check that the finned surfaces of the coils are not dirty, and clean if necessary.
Water trap Check that water is present in the water trap for the exhaust air and supply air coils.
Air purging Check frequently initially. An annual check is sufficient after the first year.
Shut off the pump and wait a couple of hours to make sure that the air bubbles have risen to the highest points in the
system, where the air-valves should be present. Open/close all valves in the system so that all trapped air can be
removed.
Valve checking Shut down the system and open/close every valve to make sure it has a smooth operation.
Pump seats Check the seals, and replace them if leakage is excessive.

ECONET®FUNCTIONAL DESCRIPTION
FUNCTION
The heat recovery function is controlled by the ECONET®fre-
quency inverter. The specific functions for the AHU must be
controlled by a separate controller (not included in the ECONET®
delivery). The functions below describe the internal heat reco-
very function for ECONET®. The process and instrumentation
diagram for ECONET®is shown below.
DELIVERY
GT40, GT41, GT42, SV40, GP41, GF10, FO40, P40.
AIR HANDLING UNIT NOT RUNNING
When the temperature GT41 is below +16°C, the pump will start
to operate at a constant low speed. When the liquid tempera-
ture GT41 is higher than +17°C, the pump P40 will stop.
START OF THE AIR HANDLING UNIT
When ECONET®receives a start-up signal, the pump P40 starts
to operate at a constant high speed after 3 minutes. After that
the pump goes to optimal sequence.
MAIN FUNCTION
ECONET®is a part of the sequence to control the supply air
temperature to its set point.

Main functions of ECONET® frequency inverter (control
sequence):
• Cooling recovery, On/Off signal
The pump P40 and frequency inverter FO40 regulate the
liquid flow to an optimal value for cooling recovery and valve
SV40 by-pass will then close. NOTE. The heat recovery
signal must be 0 %.
• Supplementary cooling, On/Off signal
The pump P40 and frequency inverter FO40 regulate the
liquid flow to the optimal value for supplementary cooling.
SV40 will open. NOTE. The heat recovery signal must be 0 %.
• Heat recovery, 0...100 %, 0..10 V signal
The pump P40 starts at minimum speed, the valve SV40
moves from open to closed, pump P40 goes from minimum
speed to optimal speed (optimal heat recovery liquid flow).
FROST AND ICE PROTECTION
• Frost protection: Protection against frost formation on
the exhaust air coil (air side).
The liquid temperature at GT41 is prevented from dropping
below the temperaure (approx.-3 °C) for frost protection by
regulating the liquid flow with the pump P40 and FO40 from
optimal liquid flow to an increased liquid flow.
• Risk of frost formation
When the liquid temperature GT41 falls below the A alarm
value (approx. -10 °C), the A-type functional alarm is given.
• Ice protection: Protection against ice formation in the heat
exchangers for supplementary heating/cooling (water side).
The liquid temperature at GT42 is prevented from dropping
below the temperature (approx. 6 °C) for ice protection by
regulating the liquid flow with the pump P40 and FO40 from
optimal liquid flow to an increased liquid flow.
• Risk of ice formation
When the liquid temperature GT42 falls below the A alarm
value (approx. 2 °C), the A-type functional alarm is given.
ALARMS
When A-alarm is generated, AHU must be stopped
immidiatly. B-alarms are only shown in display.
• Functional A-type alarms
– Risk of frost formation, GT41 ( - 10° C)
– Risk of ice formation, GT42 (+ 2 °C)
– Low pressure in ECONET®liquid circuit
• Component A-type alarms
– Signal out of range (GT 41, GT 42)
– Pump alarm
– Power supply is missing
• B-type alarms
– GT 40 signal out of range
– Bypass valve not working (SV 40)
– Liquid flow alarm

GENERAL
The control panel displays the status of the frequency inverter
and is used to set all the parameters. It is also possible to con-
trol the motor directly from the control panel.
THE CONTROL PANEL
THE DISPLAY
The display is back lit and consists of 2 rows, each with space
for 16 characters. The display is divided into six areas.
The different areas in the display are described below
Area A: Shows the actual menu number (3 or 4 digits).
Area B: Shows if the menu is in the toggle loop or the frequency
inverter is set for Local operation.
Area C: Shows the heading of the active menu.
Area D: Shows the status of the frequency inverter (3 digits).
The following status indications are possible
Acc: Acceleration
Dec: Deceleration
I2t: Active I2t protection
Run: Motor runs
Trp: Tripped
Stp: Motor is stopped
VL: Operating at Voltage limit
SL: Operating at Speed limit
CL: Operating at Current limit
TL: Operating at Torque limit
OT: Operating at Temperature Limit
LV: Operating at Low Voltage
Sby: Operating from Standby power supply
SST: Operating Safe Stop, is blinking when activated
Area E: Shows active parameter set and if it is a motor
parameter.
Area F: Shows the setting or selection in the active menu.
This area is empty at the 1st level and 2nd level menu.
This area also shows warnings and alarm messages.

CONTROL KEYS
The control keys are used to give Run, Stop or Reset command
directly in the Local mode.
LANGUAGE AND LOC/REM KEY (TOGGLE KEY)
This key has two functions:
Changes language and switching between
Loc/Rem function.
Press one second to go directly to change the language.
Press and hold the key for more than five seconds to switch
between Local and Remote function. When editing values,
the key can be used to change the sign of the value.
LOCAL MODE
Local mode is used for temporary operation. The actual status
of the frequency inverter will not change, e.g. Run/Stop condi-
tions and the actual speed will remain exactly the same. When
the frequency inverter is set to Local operation, the display will
show L in area B in the display. In local mode Econet funticons
are deactivated. The Econet A-alarm handling is still active
where all A-alarms trip the frequency inverter.
The frequency inverter will be started and stopped using the
keys on the control panel. The reference signal can be controlled
using the + and - keys on the keyboard. This can be done on
frequency inverter page 310.
REMOTE MODE
When the frequency inverter is switched to REMOTE operation,
the frequency inverter will be controlled according to Econet
control methods.
RUN L: Not used
STOP/RESET: Stops the motor or resets the
frequency inverter after a trip
RUN R: Gives a start with right rotation
