• 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 protec-
tions:
MCB
F1, F2 - 1A(5x20) MCB protection
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 terminal blocks,
• cable connection to MCB 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.
To ensure safe maintenance of the unit, it is necessary
to remove the plug from the power network.
Failure
Cause
Explanation / corrective actions
Unit is not operating
No supply voltages
Check whether the device is connected to the
plug socket
Two-pole protection device is off or a current
leakage relay is active (if installed by the in-
staller)
Switch on only if the unit condition has been
evaluated by a qualified electrician. If the sys-
tem failed, the failure MUST BE rectified prior
to switching it on.
Air supply heater or heater is not operating or
malfunctioning (if installed)
Too low air flow in air ducts activates automatic
protection
Check if air filters are not clogged
Check if fans are rotating
Manual protection is activated
Possible heater or unit failure. MUST address
the servicing staff for failure detection and its
elimination.
Too low air flow at rated fan speed
Clogged supply and/or extract air filter(s)
Filter replacement needed
Filters are clogged and no message is shown
on the remote control
Wrong time in filter timers
Shorten filter timer time till the message of
clogged filters
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
For the ventilation unit to work properly, perform the inspection of the entire ventilation system once a year. Check if the air inlet grating and room air
supply devices are clean. Check if the air duct system is not dirty. If necessary, clean or replace these devices.
