leaks, f�re or damage to household property.)
• Gloves should be worn wh�le �nstallat�on. (Fa�lure to heed th�s warn�ng may result �n �njury.)
• A ded�cated c�rcu�t breaker must be �nstalled at the or�g�n of ma�ns power supply. Th�s c�rcu�t
breaker must be prov�ded w�th a means for lock�ng (lock and key).
• The body of the un�t, room control panel and cables keep away un�t 3 m. d�stance
• Th�s product must not be d�sassembled under any c�rcumstance. Only author�zed repa�r
techn�cans are qual�f�ed to conduct d�sassembly and repa�rs. (Fa�lure to heed th�s warn�ng
may result �n f�re, electr�cal shock or �njury.)
• Connect the product properly to the ground.(Malfunct�on�ng or power leaks can cause
electr�cal shock.)
• An �solator sw�tch hav�ng m�n�mum contact gap of 3 mm �n all poles must be prov�ded as
a means of d�sconnect�ng the power supply.
NOTE: The �nstallat�ons,wh�ch �s not ava�lable for �nstallat�on and operat�on manual, �s out of guarantee.

Fan Speed Control Funct�on
Control board has 4 d�fferent fan speeds: ,,Low”, ,,Med�um”, ,,H�gh”, ,,Boost”. These fan speeds are set to spec�f�c values by
default. The max�mum fan speed �s ,,Boost”. If �t �s des�red to change fan speeds, ,,Low” and ,,H�gh” set values can be changed
by potent�ometers on control board. Control board automat�cally set the value of “med�um” by averag�ng ,,H�gh” and ,,Low” values.
Note: If ,,Low” �s set to the h�ghest and ,,H�gh” �s set to the lowest value, un�t cont�nues to run accord�ng to default sett�ngs.
Factory sett�ng values can be change.
F�lter funct�on
Th�s funct�on controls f�lter change t�me. There are 2 alternat�ves to control f�lters:
1. It records run t�me of the un�t. F�lter change t�me �s set a part�cular run t�me by factory sett�ngs. When set t�me exp�res, control
board g�ves an alert (red warn�ng l�ght flashes) for f�lter change. After f�lter clean�ng �s done, f�lter sett�ng t�me can be reset
by press�ng s�multaneously and .Hold the buttons dur�ng reset t�me that appears on screen. When countdown �s over,
press .
Note: Default run t�me set value �s changeable.
2. F�lter change t�me can be controlled by pressure sw�tch mechan�cally. W�th th�s method, when f�lter needs to be changed, control
board g�ves an alert (red warn�ng l�ght flashes). After chang�ng/clean�ng �s completed, warn�ng l�ght goes off automat�cally.
Note: To act�vate th�s funct�on, turn „d�p sw�tch 3” on
By-pass Funct�on
By-pass funct�on �s used when f�ltered fresh a�r �s des�red to
be suppl�ed to �ndoor w�thout pass�ng through heat
exchanger (trans�t�on seasons). Control board dec�des
whether by-pass module w�ll be opened or not by controll�ng
outdoor a�r temperature, return a�r temperature and set
temperature values.
Electr�c Heater Control Funct�on
Electr�c heater control funct�on controls electr�c heater that
�s used to �ncrease temperature of supply a�r. It runs due to
the return a�r temperature and set temperature values. 1 or
2 steps electr�c heater can be controlled.
Note: To act�vate th�s funct�on, turn “d�p sw�tch 1” on.

Control
Frost Protect�on Funct�on
Condensat�on occurs �ns�de the un�t where outdoor a�r temperature �s below 0°C. Heat changer can be damaged �f condensat�on
water freezes �ns�de. Control board changes fan speed per�od�cally to protect freez�ng.
Note: Th�s funct�on �s act�ve when outdoor a�r temperature �s below -3°C. Set temperature value �s changeable.
Pre-Heater Funct�on
Th�s funct�on helps to protect un�t from freeze�ng where outdoor a�r temperature �s too low. It runs due to outdoor a�r temperature.
1 step electr�c heater can be controlled.
Note: To act�vate th�s funct�on, turn “d�p sw�tch 2” on.
Heat�ng Co�l Funct�on (Opt�onal)
Th�s funct�on �s used �n un�ts wh�ch have duct type hot water co�ls. It controls the hot water co�l wh�ch helps to �ncrease supply a�r
temperature and works due to set and return a�r temperature. It can control 230V on/off valve connected to water co�l.
Note: To act�vate th�s funct�on, follow�ng must be appl�ed:
-Turn electr�c heater funct�on on. (Turn d�p sw�tch 1 on)
-Make short cut �n between HT_Fault and HT_P_Fault �nputs.
-Connect 230V on/off valve to 1.step electr�c heater control cable ends.
Cool�ng Co�l Funct�on (Opt�onal)
Th�s funct�on �s used �n un�ts wh�ch have duct type cold water co�ls. It controls the cold water co�l wh�ch helps to decrease supply
a�r temperature and works due to set and return a�r temperature. It can control 230V on/off valve connected to water co�l.
Note: To act�vate th�s funct�on, follow�ng must be appl�ed:
-Turn electr�c heater funct�on on. (Turn d�p sw�tch 1 on).
-Act�vate “Cool�ng Co�l” on un�t sett�ngs (Th�s can be done by author�zed techn�cal serv�ce or default �n factory).
-Make short cut �n between HT_Fault and HT_P_Fault �nputs.
-Connect 230V on/off valve to 2.step electr�c heater control cable ends.
Note: Th�s funct�on �s act�ve when outdoor a�r temperature �s below 0°C. Set temperature value �s changeable. When connect�ng
an after-heatr or pre-heater, the HT_FAULT or HT_P_FAUL should be br�dged respect�vely (one not used)
Boost funct�on
Th�s funct�on �s used when large amount of exhaust and fresh a�r �s needed (at the t�me of us�ng k�tchen/bathroom/wc, etc.) wh�le
vent�lat�on �s st�ll go�ng on. There are 2 boost funct�ons on controller. One of them �s on control panel, the other one �s on
control board:
1. ,,Boost” funct�on �s act�vated by press�ng for 3 seconds. After un�t runs at boost speed (max�mum speed) and dur�ng
boost t�me (15 m�nutes) �t beg�ns to run at the speed value that �s set before boost funct�on �s act�vated.
2. There �s one dry contact relay �nput (BOOST) and one 230V �nput (BOOST-AC) on control board. If one of these �nputs �s act�va-
ted, un�t beg�ns to run at ,,Boost” speed. When act�vated �nput �s pass�ve aga�n, un�t beg�ns to run at the speed value that �s set
before boost funct�on �s act�vated.
Note1: Boost speed and boost t�me are changeable
Note2: Dur�ng operat�ng at boost funct�on on Bas�c Panel, ,,H�gh” (H), ,,Med�um” (M) and ,,Low” (L) speed leds are on at the
same t�me.
