Product Information
Product Name: EU-20
Manufacturer: TECH company
Warranty Period: 24 months from the date of sale
Warranty Coverage: The manufacturer undertakes to repair the device free
of charge if defects occur due to the manufacturer’s fault.
Device Intended Usage: The device is not intended to be operated by
children.
Product Usage Instructions
- Ensure Safety: Before using the device, check the condition ofits cables. Also, make sure the controller is properly mounted and clean it if dusty or dirty.
- Principle of Operation: The task of the regulator is to switch the pump on when the temperature exceeds the pre-set value and to switch the pump off when the boiler cools down. This helps save electricity (up to 60% depending on boiler use) and prolongs the life of the device.
- Using the Regulator:
- Potentiometer: Adjust the potentiometer for desired temperature settings.
- Control Lights: The regulator has control lights indicating manual mode, power supply, and pump operation.
- Power Switch: Use the power switch to turn the device on or off.
- Fuse: The device has a 1.6A fuse for protection.
- Power supply: Connect the device’s power cord using blue (N) and brown (L) wires for 230V AC/50Hz. The yellow-green wire should be earthed for protection.
- CH Pump Output: Connect the CH pump output accordingly.
- Temperature Sensor: Install the temperature sensor in a proper place using a cable tie and protect it from external factors with insulating tape.
- Manual Mode Switch: Use the manual mode switch for manual control of the device.
- Installation: Follow the instructions for installing the temperature sensor and connecting the power cord.

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 specific 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 fire,
flood, atmospheric discharges, overvoltage or short-circuit. The interference
of an unauthorized service, wilful repairs, modifications 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 unjustifiable
service call to a defect will be borne exclusively by the buyer. The
unjustifiable service call is defined as a call to remove damages not
resulting from the Guarantor’s fault as well as a call considered
unjustifiable 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
filled-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.
Safety
Before using the device for the first 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 different 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 qualified 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 specified 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.
Principle of operation
The task of the regulator is to switch the pump on when the temperature
exceeds the pre-set value and to switch the pump off when the boiler cools
down (as a result of damping). It prevents unnecessary operation of the device
which, in turn, helps to save electricity (up to 60%, depending on the boiler
use) and prolongs the life of the device. Consequently, the device is more
reliable and the maintenance costs are reduced.
How to use the regulator
The pump activation temperature is set using a potentiometer (within the range of 25˚C-85˚C). The pump is disabled if the actual temperature drops by 2˚C below the pre-set value. It prevents regular pump activation (which affects its durability) due to small temperature fluctuation. Apart from the potentiometer, the regulator is equipped with a power switch (if the device is switched on, the control light power goes on), a switch to enable the pump manually (when the pump is enabled, Manual mode control light goes on) and a control light labelled manual which signalises the pump operation. The regulator has a WT 1,6A tube fuse-link protecting the network.
