EU DECLARATION OF CONFORMITY Hereby, we declare under our sole responsibility that EU-48 manufactured by TECH STEROWNIKI, head-quartered in Wieprz Biała Droga 31, 34-122 Wieprz, is compliant with Di- rective 2014/35/EU of the European Parliament and of the Council of 26 February 2014 on the...
AFETY 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.
ESCRIPTION Pump operation Active room thermostat mode Clock Current flue gas temperature Fan (%), pumps: CH, HW, circulating (or valve), valve calibration Standby mode Exit Pulser knob The EU–48 temperature regulator is designed for central heating boilers. It controls the water circulation pump ., the hot utility water (C.W.U.) pump, the floor heating pump, the circulation pump, the blow (fan) and the fuel feeder.
3.1 B ASIC DEFINITIONS Operation – after activation of the controller, it switches to the operation cycle and the following mes- sage is shown on the display: "OPERATION". This is the basic functioning condition of the regulator, in which the blow power and the working time and the pause time of the fuel feeder takes place in accordance with the user's settings.
Additionally, the blow force option, in which the user has the possibility to set any rotational speed of the fan in manual operation is available. 3.4 O PERATION OF THE ADDITIONAL FURNACE Tetmo-Tech boilers are equipped with two furnaces: ➔ retort furnace which is fed in sequences with the fuel from the container using a worm feeder, ➔...
of the CH pump. Operation of the CH pump proceeds all the time, until the moment when the temperature it falls below the set value in the reboiler. Then the CH pump shuts down and the hot utility water pump is activated.
3.13 F AN IN SUPPORT In this function, the user seths the operation time and the pause time of the fan at work in the support cycle. 3.14 F ACTORY SETTINGS The regulator is pre-configured for operation. However, it should be adjusted to own needs. Return to the factory settings is possible at any moment.
After pressing the knob of the pulse generator, the alarm is turned off and the regulator returns to the recently set operation mode 3.16.10 Room regulator After connection EU-48 controller to the room controller, its type should be marked: ➢ standard (two-state regulator),...
3.16.11 Boiler hysteresis This option is used to set the hysteresis of the set temperature. This is a difference between the temperature of entering the support cycle and the temperature of return to the operation cycle (for example: when the set temperature has the value of 60ºC, and the hysteresis is 3ºC, switching into the support cycle will proceed when the temperature increases to 60ºC, while return to the operation cycle will proceed when the temperature decreases to 57ºC).
To access the servicing functions of the controller, enter a four-digit code. Such code is in pos- session of the manufacturer of the boiler as well as the TECH company. ROTECTIONS To ensure maximally safe and unfailing operation, the regulator has a number of protections. In the case of an alarm, a sound signal is activated and an appropriate message is shown on the display.
4.6 F UEL CONTAINER PROTECTION On the fuel feeder there is an additional temperature measuring sensor. In the event of its signif- icant increase (above 70 C), the alarm is activated; the feeder is activated every 10 minutes, which causes pushing the fuel to the combustion chamber. This way the feeder sensor protects against fuel ignition in the container.
Incorrect connection of wires can cause damage to the regulator! NOTE: the EU-48 controller must be used for installation of the boiler, so that there is no access to cable installation slats. The regulator cannot work in a closed central heating system. Safety valves, pressure valves and a levelling tank protecting the boiler against boiling of water in the central heating system must be in- stalled.
