Short description
The Testomat®ECO is used for the automatic measuring and monitoring of the total water hardness.
The parameter to be measured is determined by the choice of the reagent and by the corresponding user program.
Reagents available for the Testomat®ECO
The various measuring parameters and ranges are determined by the choice of the reagents. The table gives a
summary of the different possibilities.

LAconsistently reliable result can be guaranteed by the TESTOMAT®ECO only with the use of original
HEYL Testomat®2000 reagents !Failure or problems which are caused by the use of different indicators
are not covered by the warranty or refund services.
When monitoring residual/total hardness, larger quantities of heavy-metal ions in the softened water can affect
the colour reaction, especially iron above 0.5 mg/l, copper above 0.1 mg/l and aluminium above 0.1 mg/l
(brownish-red colour indication).The measuring is possible in a range of pH 4-10.5.
At a concentration of more than 100 mg/l of CO2(carbon dioxide) in the water, the excess carbon dioxide must
be removed by installing a Type R aerator in the feed water line to the TESTOMAT®ECO unit. When using the
TESTOMAT®ECO for monitoring a de-carbonisation installation (weakly acidic cation exchanger) without its
own irrigator, a small scale irrigator must always be installed upstream of the device.
Concentration values of these ingredients can be determined safely and simply with our TESTOVAL colorimetric test
comparators.

Notes for the user
•Repeated switching 'on' and 'off':
Wait at least for 5 seconds before you switch the unit repeatedly 'on' or 'off' at the main switch.
• Observation of the environmental conditions:
In order to guarantee a reliable operation, the unit must only be used under the environmental conditions described
in the technical data. Protect the controller against excessive humidity, condensation and water-splash.
• Safety seal:
The original seals attached during manufacture (e.g. EPROM labels) must not be broken, otherwise all warranty
rights are lost.
• Malfunction / repair of defective units:
The repair of a defective unit is only possible when the unit is dismantled and returned to us with a description of the
fault.This in no way affects the guarantee rights. In addition, please inform your supplier of the reagent type used and
of the quality of treated water measured.
Before you return the unit for repair, remove the reagent bottle and ensure that the measuring chamber is flushed out
and empty.
• Electrical load capacity
The maximum electrical load capacity of the relay outputs and the total power rating must not be exceeded.
• Operate the Testomat® ECO strictly in accordance with the manufacturer's instructions.
• Environmental protection regulations
Please observe the environmental protection regulations and collect any unused reagent for safe disposal in
accordance with local statutory requirements.
Operational Checks
Careful handling of the unit increases both the operational reliability and the service life!
Therefore the following visual inspection should be carried out at regular intervals.
•Are the hose connections with the dosing pump free of leaks?
•Is there any air inside the dosing hoses?
•Are all the water connections free of leaks?
•Are the doors of the unit properly closed?
•Is the unit unduly contaminated with dirt?
Maintenance and servicing notes
(see page 17)
Safety notes
• The unit must be installed and operated in compliance with the relevant standards (e. g. DIN, VDE, UVV).
• Some functions (e. g. the manual analysis) allow the direct manipulation of the installation without locking or
monitoring. These functions may only be used by trained staff and for this reason they are only accessible after a
pass word has been entered.
• If you observe the unit malfunctioning, switch it off immediately. Then shut off the water supply and contact your
supplier.
• Do not attempt to repair the unit yourself (loss of warranty rights); instead always get in touch with the authorised
service staff. This is the only way a reliable and safe operation of the unit can be ensured.
•After a protective circuit (fuse) has tripped, first of all, attempt to correct the cause of the malfunctioning (e. g. replace
the solenoid valve) before reactivating the protective circuit. Frequent tripping is always due to a fault which, in
certain circumstances, may also cause damage to the unit.
• Observe the safety notes about working with reagents, chemicals and cleaning agents.
Ignoring these notes can result in damage to the unit as well as the installation and may result in a loss of
warranty rights.

Dimensioned sketch
Installation and commissioning
Installation and commisioning must be undertaken only by
authorised technicians!
Installation
The unit should be fixed vertically!
Avoid tension of the housing.
The unit doors swing to the left when they are opended. Please
ensure that there is sufficient space for opening them. In this
way, you facilitate the electrical installation and later
maintenance and service work.
Electrical connection
Check supply voltage on the rating plate!
Basic requirements
The external cables (e.g. water meter, interface) should be kept as short as possible and clear of power cables.
Connection
Loosen both fastening screws and open the upper door. Pierce the required rubber cable glands with a screwdriver and
insert the cable (1). Then pull back the cable until the bush (2) has been turned over. Ensure that the leads are held
securely in the terminals then close the upper door after the installation is completed using the two fastening screws.
Mains water supply
The temperature of the sample water must be between 10 °C and 40 °C. Higher water temperatures can lead to
damage to all parts coming into contact with water (e. g. filter housing, measuring chamber)!
Lower water temperatures can cause misting on the sight-glass windows.
LIn the event of higher temperatures, the Type KCN cooler must be installed in the branch line of the TESTOMAT®
ECO.
Hot water can lead to scalding!
The branch line should be positioned as close as possible to the outlet from the water softening plant. The branch line
to the Testomat®ECO with a hand-operated shut-off valve must be kept as short as possible and not longer than a
maximum of 5 meters. It is important that the branch line connection is taken vertically from the top of the main soft
water line in order to prevent dirt particles from entering into the measuring chamber.
When operating the Testomat®ECO with the pressure range of 3 to 8 bar install the valve and the regulator/ filter
housing from our range.
Plug connector
The unit is equipped as a standard with a plug connector for opaque plastic hoses 6/4 x 1 (external diameter 6 mm/
internal diameter 4 mm).
Quick-acting coupling (accessory: Optional adapter for water inlet, Order no. 40123)
LOnly with installed regulator / filter housing (optional available)
When fabric reinforced pressure hoses (e.g. for existing installations) are used, please replace the plug connector at the
controller and filter housing with a plug for the quick-acting coupling (not included with the delivery).

4 / 19
Operation with small aerator
If the sample water to the TESTOMAT®ECO contains more than 100 mg/l of CO2,it will be necessary to install a Type R
small aerator. The aerator must be installed at least 1 m above the TESTOMAT®ECO.
Water to drain
The feed water flows through the measuring chamber then, via the outlet pipe, to the drain (hose connection internal
diameter 14 mm). Make sure, by using a funnel for example, that the water can run freely to drain and cannot back-up
into the measuring chamber. A hose impervious to light should also be used for the drain pipe (to discourage algae
formation).
Commissioning
1. Afull reagent bottle must be connected before commissioning and switching on. Attach the vacuum connection onto
the reagent bottle using the union nut.
2. Switch the unit 'on' and press the "STANDBY" key. In this mode, an analysis is prevented from being carried out
before a correct program has been entered which could possibly result in an error or alarm message.
3. Then bleed the dosing pump and the capillary by repeatedly pressing the "Manual" key on the dosing pump. Ensure
all air is removed from the tubing ! (If necessary tighten up the connections.)
4. Program the unit as applicable to your requirements, e. g.: - Mode of Operation - Type of reagent
- Displayed unit - Limit values
- Flush time/interval - Analysis interval
For a description of programming see from page 12.
5. Then remove all air from the water supply side of the unit by manual flushing.
"M" ºSERVICE ºMANUAL OPERATION ºFLUSH ("ENTER" press repeatedly).
You should continue flushing until no bubbles can be seen in either the measuring chamber or the filter housing.
6. Check all connections for tightness.
7. By pressing the "Manual" key you carry out the first analysis.

Alarm Fault message
The "Alarm" output is a volt-free change-over relay contact. During trouble-free operation the contact between the
terminals 16 – 17 is closed and the one between terminals 15 – 16 is open. When the voltage fails or the alarm is
activated, the contact between terminals 15 – 16 is closed and the one between 16 – 17 is open.
T
The unit is equipped with a range of monitoring functions.
- The "Alarm" output remains activated (with terminals 15 – 16 closed) as long as the fault persists.
-The red LED "Alarm" and the text on the display indicate a fault.
-The error signal at the "Alarm" output is deleted by cancelling the fault with the "Horn" key.
-An error message can only be deleted after the fault has been corrected.
- Exception: “Reagent low level“, this message is confirmed in the M-menu by entering in the new reagent level.
The following faults activate the "Alarm" output and are displayed:

Function characteristics
Mode of operation (Analysis controller)
1. Time control: Internal triggering by a timer. The shortest interval = 0 minutes between analyses, longest interval
= 99 minutes.
(see page 10, interval periods)
LThe analysis interval is determined by the duration of the set flush times the programmed (interval) and the
duration of the analysis. The analysis duration is a direct function of the value to be measured.
2. Quantity control: Triggered by the water meter.
Minimum interval = 1 litre, maximum interval = 9999 litres.
After the programmed water quantity is measured, the analysis is carried out. Prior to the analysis, the capillary
and the measuring chamber are flushed (observe the programmed flush times).
LThe current analysis interval can be interrupted by making contact at the "Stop" input.

Displayed unit
Programmed hardness unit is displayed. You have the choice of °dH, °f, ppm CaCO3and
mmol/l. The unit entered will now be displayed as programmed.
Type of reagent
Select the reagent type you are utilising in the unit, e. g. reagent TH 2005 means 8.93 ppm CaCO3upper limit of the
measuring range and 0.89 ppm CaCO3lower.
Setting the timer
Flush
In order to ensure the analysed sample represents the current value, the sampling tube must be sufficiently well flushed
taking its length into consideration. After the installation has been out of operation for a longer period or in the case of
long analysis intervals, it is sensible to select a flushing time in excess of 60 seconds. Flush is initiated by
simultaneously opening the Testomat®ECO’s inlet and the outlet valves.
LThe analysis interval directly depends on the programmed flush time. If a flush time of, for example, 90 seconds is
set, the analysis interval itself cannot be shorter than 90 seconds.
Example: For 3 bar pressure, a connection longer than 5 m, an internal tube diameter of 4 mm, and a minimal
internal flushing time of 10 seconds is required to ensure a valid sample is taken from the sampling tube.
The quantity of flush water for an internal flush of 1 minute is 0.5 litre.
Interval pause
In the case of timed triggering of the analysis, the interval between two analyses (plus flush time) is determined by the
interval pause. The shortest interval can be 0 minute. In this case, the analyses are carried out continuously. The
longest interval is 99 minutes.
Monitoring of limit value
Two outputs for the limit value are available for monitoring. You can program the limit value on a continuous scale. The
range for the limit value depends on the reagent type used and on the programmed unit. The functions of these outputs
can be programmed independently from each other.
When the limit value LV1 is exceeded, limit value control display lights up LV1 RED and the relay output LV1 reacts as
programmed in the switch function. As long as this limit value is not exceeded, the display lights up GREEN.
The unit operates in the same way for the limit value LV2.

11 / 19
Hysteresis
Each limit value output reacts only after the 1st,2nd or 3rd bad analysis result has been detected (suppression of the first
or the second measured value).
This increases the reliability during the evaluation of the analysis e. g. after the measuring point has been switched over
or if the sampling line has possibly not been flushed sufficiently. The hystereses of the two outputs LV1 and LV2 can
be set independently from each other.
Operation: With a hysteresis of 2 a further analysis is carried out immediately after the limit value has been exceeded.
Only if the limit value of this analysis is exceeded again, the corresponding output is energised. If you have set a
hysteresis of 3, the corresponding output reacts only after the limit value has been exceeded for the 3rd time in
succession.
Logic functions of the limit value outputs LV1 and LV2
Logic function 0, Duration
Output relay LV1 or LV2 pulls up when the measured value rises above limit value LV1 or LV2. If the measured value
falls below the limit value LV1 or LV2 the relevant relay drops out again.
Logic function 1, Impulse
If the measured value rises above limit value LV1 or LV2, the relevant output pulls up for a set time t. Independent of the
time taken for the limit value to rise above the set limit, the relevant output always remains in the "ON" position for the
set time.
Logic function 2, Interval
If the measured value rises above one limit value, the relevant output pulls up at intervals with the time
set.(Impulse/Pause)
Logic function 3, Two-point
If the upper limit value LV1 is exceeded, the output relay LV1 pulls up. If the lower limit value LV2 falls below the set
limit, output relay LV1 drops out.
The output relay LV2 pulls up according to the programmed logic function.
LThis function is possible only if different values are selected for LV1 and LV2. For
example for LV1 =0.2° dH and for LV2 =0.1° dH.
BOB-Operation (BOB = Operation without constant supervision)
The Testomat ECO conforms to the german TRD 604 safety standard for monitoring of water hardness associated with
steam boiler installations, when operation without constant supervision is a relevant safety feature (= Betrieb Ohne
ständige Beaufsichtigung = BOB -operation).
When the BOB function is programmed, the unit constantly monitors the reagent quantity available. For calculating the
reagent consumption per analysis, a measured value of 1.48 ppm CaCO3(0.015 mmol/l alkaline earth ions) is used. An
alarm is activated if the residual reagent quantity is insufficient for the set BOB period of 72 hours.
BOB on: Continuous monitoring of the residual reagent quantity. ALARM message when the available quantity falls
below the minimum quantity for the BOB period: “Alarm“ flashes, the Alarm output is energised.
BOB off: Without BOB function: the residual reagent quantity is only monitored for the minimum quantity (10 %
level).
Example: BOB-Duration = 72 Hours Number of analyses per hour = 10
Necessary quantity of reagent for 72 h = 72 h x 10 Analysis/h x (3 x 30) µl/Analysis = 64.8 ml.
(That corresponds to approx. 13% of a full level bottle)
Funktion STOP
The active analysis interval can be interrupted through contact with the stop input. The active condition has to be
programmed according to your requirements.

Maintenance
Regular maintenance is necessary in order to ensure trouble-free operation of the unit!
Please carry out the maintenance work described in the following section when
Sthe programmed maintenance date has been reached (display "maintenance date exceeded")
Sthe unit displays the following error messages: " Mf.dirtiness " or " Reagent low level"
Sthe last maintenance was carried out more than 6 months ago
Never use organic solvents to clean the measuring chamber and other plastic parts!
Please observe the safety rules when handling cleaning agents!
LIf the measuring range has been exceeded over an extended period, a coloured coating can form on the sight-
glass windows. This stubborn coating can be easily removed with alcohol.
Description of maintenance work
Cleaning the measuring chamber and the sight-glass windows
1. Switch the unit 'off' or press the "STANDBY" key (drain measuring chamber completely !).
2. Close the hand-operated valve on the branch line to the TESTOMAT®ECO.
3. Unhook toggle type fastener, tip the measuring chamber upwards and extract.
4. Slacken both sight-glass window holders, extract and clean the sight-glass windows.
5. This stubborn coating can be easily removed with alcohol.
6. Clean the measuring chamber with 10% hydrochloric acid and then rinse well.
7. After cleaning, replace the sight-glass windows and secure these with the sight-glass windows holder
(do not forget the O-ring seals and check for correct seating in the recess).
8. Insert the measuring chamber by tilting it backwards until the slot engages with the rear
guide bar and press down. Finally secure the chamber with the toggle type fastener.
Cleaning the filter housing
1. Close the hand-operated valve on the branch line to the TESTOMAT®ECO.
2. Undo the hose connections to the filter housing.
3. Unscrew inlet connection remove sealing ring, spring and filter strainer and clean.
4. Extract the retaining pin and withdraw the flow regulator and finally remove the valve
body.
5. Clean filter housing with water or alcohol and and reassemble.
Insert filter strainer point downwards!
6. Install the hose connections to the filter housing.
Water Leakage from of the seals can result in damage to parts of the unit
TTip: Please check the unit for leaks before carrying out the first analysis
•switch the unit to STANDBY
•manually fill the measuring chamber •manual reagent dosing (key "Manual") •check the connections and seals for leaks
Note on care for the unit
The surface of the unit has not been treated. Therefore, a contamination with reagent, oil or grease should be avoided.
Should the housing, however, be contaminated, please clean the surface with isopropanol (never use other solvents).
