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.
DESCRIPTION OF THE CONTROL PANEL Pump 1 Pump 2 Pump 3 Stadnby Exit button – to exit, or discard tti Pulser knob – to enter MENU, select and 5
SCREEN VIEW– ICONS: gap between icons indicating pump and room controller status pump operating in "sensor failure" mode circulation pump pump operating in "temperature mode"; turn-off threshold was reached same as above but the turn-off threshold was not reached pump operating in "temperature alarm mode"; alarm threshold was exceeded on one of the sensors room controller open (too low temperature in the room)/pump operating in room mode room controller closed (sufficient temperature in the room)/pump oper
CONTROLLER FUNCTIONS MANUAL OPERATION By using this function the user can manually start any active actuator of the controller, independently from other actuators, and check the alarm operation. Pressing the PULSER turns the individual pumps on or off. PARAMETERS P1/P2/P3 This function allows selecting parameters of P1, P2 or P3 pump to proceed to detailed settings of the pump operation. 4.2.1 Operation type Here the type of the pump to be started should be defined.
Temperature operation 1. Turning-on -Turn-on sensor – sensor should be defined to provide the pump with current temperature which will determine the pump turn-on threshold. -Turn-on threshold – allows setting the turn-on threshold temperature; the pump will operate if the actual temperature exceeds the threshold value. -Temperature alarm – the setting allows turning the temperature alarm function on or off.
Delta When connected in that mode the pump will operate based on the temperature difference between two selected sensors with the turn-on threshold on the source sensor and the turn-off threshold on the receiver (or a signal from the room controller).
5. Hysteresis - applies to both the turn-on threshold value (source) and turn-off threshold value (receiver). The option is used to delay the controller response to temperature change when the temperature is fluctuating around the said thresholds. 6. Sensor alarm operation - allows defining if the pump operation should be triggered by an alarm of any of the sensors. 7. Anti-freezing - the setting allows turning the anti-freezing function on or off.
SENSORS This option allows defining the type of the sensor connected: • • • none – no sensor connected to the input – the sensor will not be selectable in all parameters. KTY – KTY-type temperature sensor connected to the input. PT1000 – PT1000 temperature sensor connected to the input.
MAINTENANCE Before and during the heating season it is necessary to inspect the condition of cables inside EU-427i controller. Additionally, the controller fasteners needs to be checked and the controller should be cleaned to remove dust and other dirt. Also the efficiency of motor earthing should be measured.
EU DECLARATION OF CONFORMITY Hereby, we declare under our sole responsibility that EU-427i manufactured by TECH STEROWNIKI, head-quartered in Wieprz Biała Droga 31, 34-122 Wieprz, is compliant with Directive 2014/35/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of Member States relating to the making available on the market of electrical equipment designed for use within certain voltage limits (EU OJ L 96, of 29.03.2014, p.
