Perform connecting of control unit according to the figure (Fig. 5A, 5B, 5C, 5D) and instructions detailed hereunder.
▪ Do respect safety and security prescriptions! All interventions shall be performed in voltage-free status!
▪ Installation of box:
▫ Locate the box at eye level, if possible, to enable good visibility of display and buttons could easily be operated
▫ Before setup, remove control panel from box in order to prevent damages during drilling and fixation
▫ You shall not leave the box cover hanging on the flat multicore cable in any case! When installing, you shall provide a support to the box cover or have it removed by
disconnecting the easily dismantling line terminals!
▪ Connecting cables:
▫ Regarding to cable sizes see technical data
▫ Insert cables needed into the box through cable glands, from below, if possible
▪ Preparation of connections: terminal blocks shall be connected in voltage-free status, as shown in figure (Fig. 5A, 5B, 5C, 5D), in any case, you shall respect the maximum
loadability restlessly, as indicated in technical data
▫
Power supply input (230V):
take care of correct order of phase and neutral wires when connecting power supply and other equipments
▫
Fan outputs (230V):
◦ at fan terminals neutral is permanently present; phase shall be switched on by fan-relay
◦ if the fan to be connected to output having a higher power consumption than indicated among technical data or being of 380V type, use a 230V relay for
switching, which can directly be connected to the place of fan
▫ Burner outputs (230V):
depending on burner type, output shall not be connected necessarily to terminal block points marked by ’Stage2’, ’Reset’ and ’Error’, as the
unit being operational without them, only some functions cannot be accessed
◦ ’Neutral’ output: means the neutral wire of burner; neutral shall permanently be present, not switched
◦ ’Stage1’ output: phase output switched by Stage1-relay
· in case of a single stage burner or radiator, the phase wire of burner/radiator shall be connected here
· in case of a double stage burner or radiator, the phase wire of first stage of burner/radiator shall be connected here
◦ ’Stage2’ output: phase output switched by Stage2-relay
· in case of a single stage burner or radiator, it is not in use (shall be left free)
· in case of a double stage burner or radiator, the phase wire of second stage of burner/radiator shall be connected here
◦ ’Reset’ output: neutral output switched by the reset-relay, which terminal block shall receive zero potential when burner/radiator confirmed (when not in
use, it shall be left free)
The reset output can be activated when zone error confirmed.
◦ ’Error’ input: 230V error message input for burner/radiator, to which phase shall be switched by burner/radiator when its function failed (when not in use, it
shall be left free)
Error signal given to input shall only serve for information to control unit, its function not being influenced thereby (a zone error symbol will appear
which can be confirmed)
▫
Error message output:
general error message of control unit (potential-free NO), which shall be activated synchronously with warning error symbol appeared on
screen: if error signalled by the symbol, the complementary relay will be energised and terminal block points of ’Complementary output’ shall be short-circuited
▫
Emergency stop input:
this is a low voltage NC (normally closed) input serving for connecting emergency stop button: if the button pressed, the input shall be cut and
the functions of both heating radiator and fan shall be disabled by control software
▫
Fan thermal-relay inputs:
this is a low voltage NC (normally closed) input serving for connecting breaker contacts of fan thermal relay switch: if fan function failed
and overcurrent being present, the thermal relay input contact shall be cut and the functions of both heating radiator and fan shall be disabled by control software
