Safety
Before using the device for the rst time the user should read the
following regulations carefully. Not obeying the rules included in this
manual may lead to personal injuries or controller damage. The user’s
manual should be stored in a safe place for further reference. In order to
avoid accidents and errors it should be ensured that every person using
the device has familiarized themselves with the principle of operation as
well as security functions of the controller. If the device is to be sold or
put in a dierent place, make sure that the user’s manual is there with
the device so that any potential user has access to essential information
about the device.
The manufacturer does not accept responsibility for any injuries or
damage resulting from negligence; therefore, users are obliged to take
the necessary safety measures listed in this manual to protect their lives
and property.
We are committed to protecting the environment. Manufacturing
electronic devices imposes an obligation of providing for environmentally
safe disposal of used electronic components and devices. Hence, we have
been entered into a register kept by the Inspection For Environmental
Protection. The crossed-out bin symbol on a product means that the
product may not be disposed of to household waste containers. Recycling
of wastes helps to protect the environment. The user is obliged to transfer
their used equipment to a collection point where all electric and electronic
components will be recycled.
WARNING
• High voltage! Make sure the regulator is disconnected from the
mains before performing any activities involving the power supply
(plugging cables, installing the device etc.)
• The device should be installed by a qualied electrician.
• Before starting the controller, the user shoud measure earthing
resistance of the electric motors as well as the insulation resistance
of the cables.
• The regulator should not be operated by children.
WARNING
• The device may be damaged if struck by a lightning. Make sure the
plug is disconnected from the power supply during storm.
• Any use other than specied by the manufacturer is forbidden.
• Before and during the heating season, the controller should be
checked for condition of its cables. The user should also check if the
controller is properly mounted and clean it if dusty or dirty.
WARRANTY CARD
TECH company ensures to the Buyer proper operation of the device for the period of 24 months from the date of sale. The
Guarantor undertakes to repair the device free of charge if the defects occurred through the manufacturer’s fault. The device should
be delivered to its manufacturer. Principles of conduct in the case of a complaint are determined by the Act on specic terms and
conditions of consumer sale and amendments of the Civil Code (Journal of Laws of 5 September 2002).
CAUTION! THE TEMPERATURE SENSOR CANNOT BE IMMERSED IN ANY LIQUID (OIL ETC). THIS MAY RESULT IN DAMAGING
THE CONTROLLER AND LOSS OF WARRANTY! THE ACCEPTABLE RELATIVE HUMIDITY OF THE CONTROLLER’S ENVIRONMENT IS
5÷85% REL.H. WITHOUT THE STEAM CONDENSATION EFFECT.
THE DEVICE IS NOT INTENDED TO BE OPERATED BY CHILDREN.
Activities related to setting and regulation of the controller parameters described in the Instruction Manual and parts wearing
out during normal operation, such as fuses, are not covered by warranty repairs. The warranty does not cover damages arising
as a result of improper operation or through the user’s fault, mechanical damage or damage created as a result of re, ood,
atmospheric discharges, overvoltage or short-circuit. The interference of an unauthorized service, wilful repairs, modications and
construction changes cause the loss of Warranty. TECH controllers have protective seals. Removing a seal results in the loss of
Warranty.
The costs of unjustiable service call to a defect will be borne exclusively by the buyer. The unjustiable service call is dened as
a call to remove damages not resulting from the Guarantor’s fault as well as a call considered unjustiable by the service after
diagnosing the device (e.g. damage of the equipment through the fault of the client or not subject to Warranty), or if the device
defect occurred for reasons lying beyond the device.
In order to execute the rights arising from this Warranty, the user is obliged, at his own cost and risk, deliver the device to
the Guarantor along with a correctly lled-in warranty card (containing in particular the sale date, the seller’s signature and a
description of the defect) and sales proof (receipt, VAT invoice, etc.). The Warranty Card is the only basis for repair free of charge.
The complaint repair time is 14 days.
When the Warranty Card is lost or damaged, the manufacturer does not issue a duplicate.

Description
EU-19 antystop is intended for controlling the central heating pump
(CH). The pre-set temperature is dened using a potentiometer. The
main task of the controller is to activate the pump when the pre-set
temperature value is reached and deactivate it when the CH boiler
temperature drops by 20 C below the pre-set value. Such characteristics
prevent unnecessary pump operation, which saves electricity, extends
the life of the pump and enhances its reliability. ST-19 controller also has
an additional feature – ANTI-STOP, which prevents CH pump stagnation
outside the heating season ( the pump is activated every 10 days for 1
minute).
Controller functions:
• controlling CH pump
• anti-stop
Controller equipment:
• CH temperature sensor
• Potentiometer for setting the desired temperature
Principle of operation
EU-19 antystop is intended for controlling the central heating pump
(CH). The main task of the controller is to activate the pump when the pre-
set temperature value is exceeded and deactivate it when the CH boiler
cools down (due to damping). Such characteristics prevent unnecessary
pump operation, which saves electricity (up to 60% depending on the CH
boiler use), extends the life of the pump. It also enhances its reliability
and reduces the maintenance costs.
ST-19 controller oers anti-stop function which prevents CH pump
stagnation. The pump is activated every 10 days for 1 minute.
Additionally, every hour the time data is saved in non-volatile memory
(EEPROM), which ensures that the timing is continued even in the event
of voltage failure.
How to congure parameters
Pump activation temperature is adjusted using the potentiometer
within the range of 25⁰C - 85⁰C. The pump is disabled when the actual
temperature drops by 2⁰C below the pre-set value (set up using the
potentiometer). It prevents periodical pump switching due to slight
temperature uctuation as it would have a negative impact on the life
of the pump.
Apart from the potentiometer, the regulator also has two switches - one
for activating the device (indicated by the power supply light) and the
other for manual pump activation ( indicated by the manual operation
light).

Installation & How to use the device
The controller should be installed by a qualied person.
The sensor should be installed on the CH boiler output with the use of a
cable tie and protected from the inuence of external factors with the use
of an insulating tape (it cannot be dipped in any liquid).
The pump power cord should be connected in the following way: blue and
brown:230V, yellow-green (protective) should be earthed.
The distance between the mounting holes is 110mm
