• Electrical connection can only be implemented by the qualified electrician in accordance with the applicable international and national electrical
safety requirements and requirements for installation of electrical devices.
• Use only power source which meets the requirements specified on the device label.
• Power supply cable should be selected based on the electrical specification of the device. If the device power supply line is far from the unit, the
distance and voltage drop should be considered.
• Device must be earthed.
• Install the control panel at the designated place.
• Install the supplied connection cablebetween the control panel and the HVAC unit. It is recommended to install the control panel separately from
the power cables.
Note: If cable is used together with other power cables, shielded control panel cable with earthed shield should be used.
NOTE: The remote control panel can be connected and (or) disconnected only after disconnecting the power supply for the HVAC unit.
• Select the desired fan rotation speed and the supply air temperature using the remote controller.
Control system of the unit has an integrated protection against short-circuit for these functional components. The controllers have the following
protections:
MCB
F1, F2 - 1A(5x20) MCB protection
EX2
F1 - 1A(5x20) supply air fan protection;
F2 - 1A(5x20) outdoor air fan protection
F3 - 6,3A(5x20) outdoor air preheater protection
F4 - 1,5A(5x20) supply air heater protection
F6 - 2A(5x20) supply/outdoor air dampers actuators‘ protection DO5 and DO6
To ensure safe maintenance of the unit, it is necessary to remove the plug from the power network.
Prior to start-up the system must be thoroughly cleaned. Check whether:
• operation systems and unit elements as well as automation and automation devices were not damaged during installation,
• all consumers are connected to power supply and fit for service,
• all necessary automation elements are installed and connected to power supply and MCB, EX1, EX2 terminal blocks,
• cable connection to MCB, EX1, EX2 terminal blocks
comply with the existing power connection diagrams,
• all electrical equipment protection elements are properly connected (if they are additionally used),
• cables and wires correspond to all applicable safety and functional requirements, diameters, etc.,
• earthing and protection systems are properly installed,
• condition of all seals and sealing surfaces is proper.
Fault
Possible reason
Troubleshooting
The unit doesn’t work
No power supply
Check whether the device is connected to the
plug socket
Bipolar protection device is not activated or
triggered leakage current relay (if installed by
the installer)
Turn on only after qualified electrician in-
spection of the unit. If there is a fault in the
system before turning on the failure MUST be
removed.
Improper closing of the unit’s door
Visually make sure if the door is properly
closed
Supply air heater or pre-heater don’t work or
work intermittently (if installed)
Insufficient air flow in the duct system, auto-
matic protection is activated
Check the air filters and fan rotation
Manual protection is activated
NECESSARY to contact service
Insufficient air flow in comfort mode
Contaminated supply air filters
Change filters
No warning about contaminated air filters
Improper time setting of the filter timer
It is necessary to shorten filter timer period for
contaminated filter warning
The controller is used with NTC sensors. Default sensor NTC
10 kΩ β (25/85) 3977
Limits for temperature measurement -30 ...105 °C.
Accuracy - ± 0,2 %
Safety class – IP-54
