TECHNICAL DATA
The unit is designed for indoor application with the ambient temperature
ranging from +1 °C up to +40 °C and relative humidity up to 60 % without
condensation. In cold, damp rooms, there is a possibility of freezing or
condensation inside and outside the casing. In order to prevent condensation
on the internal walls of the unit, it is necessary that the surface
temperature of the casing is 2-3 °C above the dew point temperature of the
transported air. The unit should be operated continuously, and in cases where
ventilation is not necessary, reduce the air flow of the fans to a minimum
(20%). This will ensure a favorable indoor climate and reduce the amount of
condensation inside the unit, which can damage electronic components. Never
use the unit for dehumidification, for example, of new buildings. The unit is
rated as a Class I electrical appliance. Hazardous parts access and water
ingress protection rating: IP22 for the unit connected to the air ducts IP44
for the unit motors The unit design is constantly being improved, thus some
models may be slightly different from those described in this manual.

DESIGN AND OPERATING PRINCIPLE
The unit has the following operating logic: warm stale extract air from the
room flows into the unit, where it is filtered by the extract filter, then air
flows through the heat exchanger and is exhausted outside by the extract fan.
Cold fresh air from the outside flows into the unit, where it is cleaned by
the supply filter. Then the air flows through the heat exchanger and is
directed to the room with the supply fan. Heat energy of warm extract air is
transferred to clean intake fresh air from the outside and warms it up. The
air flows are fully separated while flowing through the heat exchanger. Heat
recovery minimizes heat losses, which reduces the cost of space heating in the
cold season.

The service side of the unit is equipped with a detachable plate for filter
and heat exchanger cleaning and replacement operations. The control unit is
positioned inside the unit casing. The power cable and grounding cables are
connected to the control unit via the cable gland at the side of the unit. The
temperature differential between the supply and extract air flows leads to
condensate generation. Condensate is collected in the drain pan and is removed
outside through the drain pipe.
Additional components (not included in the delivery set, optionally available
for purchase): Humidity sensor (FS2 is connected to the terminal block, HR-S
is connected to the controller). Based on the humidity sensor readings the
unit keeps the set indoor humidity level. When the extract air humidity
crosses the set humidity point, the unit goes automatically to the high speed.
When the indoor humidity drops down below the set point, the unit reverts to
the previous operation mode. CO2 sensor (connected to the controller).
Measures indoor CO2 concentration and sends control signal to control the fan
capacity. Air capacity control based on CO2 concentration is an efficient
energy-saving ventilation solution.

UNIT OPERATION MODES
Heat recovery Warm stale extract air from the room flows into the unit, where
it is filtered by the exhaust filter, then air flows through the heat
exchanger and is exhausted outside by the exhaust fan. Cold fresh air from the
outside flows into the unit, where it is cleaned by the supply filter. Then
the air flows through the heat exchanger and is directed to the room with the
supply fan. Supply air is heated in the heat exchanger by transferring the
heat energy of warm and humid extract air to the cold fresh air. The air flows
are fully separated while flowing through the heat exchanger. Heat recovery
minimizes heat losses, which reduces the cost of space heating in the cold
season.
Freeze protection The heat exchanger freeze protection function of the unit is
implemented with a temperature sensor installed in the exhaust air duct
downstream of the heat exchanger. In case of a freezing danger the supply fan
is turned off and the heat exchanger is warmed up with warm extract air flow.
The recommended sensor or thermostat operating temperature is +3 °C (exhaust
air temperature behind the heat exchanger). If necessary, this set point can
be edited using the software. After temperature increase the unit returns to
the previous operation mode.
Summer Cooling mode The bypass dampers are open and both air flows do not come in contact with the heat exchanger.

TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE ANY MAINTENANCE OPERATIONS.
FOLLOW THE SAFETY REGULATIONS WHEN CARRYING OUT MAINTENANCE. Maintenance
operations of the unit are required 3-4 times per year. It includes general
cleaning of the unit and the following operations:
1. Filter maintenance (3-4 times per year). Dirty filters increase air resistance in the system and reduce supply air volume. The filters require cleaning not less than 3-4 times per year. Vacuum cleaning is allowed. After two consecutive cleanings filters must be replaced. For new filters, contact the Seller. To clean or replace the filters, detach the removable plates located on the service side of the unit. After cleaning install the filters and the detachable plates in the reverse order.
2. Heat exchanger maintenance (once per year). Some dust may accumulate on the heat exchanger even in case of regular maintenance of the filters. To maintain the high heat recovery efficiency, regular cleaning is required. Before removing the heat exchanger, detach the removable plate located on the service side of the unit. Remove the heat exchanger and the drain pan from the unit. Flush the heat exchanger with warm detergent solution. After cleaning install the dry heat exchanger with the drain pan back to the unit.
3. Drain system maintenance (once per year) The condensate drainage (drain line) may get clogged by dirt and dust particles contained in the exhaust air. Pour some water inside the drain pan to check the pipe for clogging. Clean the U-trap and the drain pipe if required. 4. Technical maintenance of air duct system (every 5 years). Even regular fulfilling of all the maintenance operations prescribed above may not completely prevent dirt accumulation in the air ducts, which reduces the unit capacity. Duct maintenance means regular cleaning or replacement. 5. Control unit maintenance (if necessary). The control unit maintenance must be performed by an expert qualified for unassisted operations with electrical installations with the voltage up to 1000 V after careful reading of the user’s manual.
