ment has been selected as the Rh level

setting (humidity setting, Section 3.7).

The setpoint for CO

adjustment is cho-

sen with the + and – buttons.

The adjustment interval for humidity and

carbon dioxide adjustments is selected

with the + and – buttons. The adjust-

ment interval refers to minutes.

The desired cell bypass temperature

is selected with the + and – buttons. If

outdoor temperature is lower than cell

bypass temperature, the summer/win-

ter damper is in the winter position.

The mode of operation of the switch

(either ﬁ replace or booster switch) is

selected with the + and – buttons.

The address of the control panel is

changed with the + and – buttons. Two

control panels cannot have the same

Winter parameter A

Winterparam. A

Increasing the value decreases the freezing of the HR cell. The unit ope-

rates optimally on the factory settings. There is no need to adjust this set-

point except in extreme problem situations, and even then it is advisable

to contact Vallox Maintenance. The adjustment is made with the + and

– buttons. See the table for the factory setting.

3.22

Winter parameter B

Winterparam. B

Decreasing the value decreases the freezing of the HR cell. The unit

operates optimally on the factory settings. There is no need to adjust this

setpoint except in extreme problem situations, and even then it is advisab-

le to contact Vallox Maintenance. The adjustment is made with the + and

– buttons. See the table for the factory setting.

A water or electric radiator is selected

with the + and – buttons, depending on

the type of post-heating radiator the unit

is equipped with. Note! Choosing the

wrong type of post-heating may cause

a faulty post-heating function.

An electric or MLV radiator is chosen

according to ventilation unit type with

the + and – buttons. This unit can be

used only for electric heater setting

Changing MLV radiator setpoint. When

outdoor air temperature goes below this

setpoint, the ventilation unit starts the

MLV pump. If a message "Preheating

not in use" is displayed, no setpoint is

in use.

Choose one of the two modes of mel-

ting to be used in the unit. Melting is

done either by stopping the supply air

fan or by bypassing the HR cell.

The winter function of the unit is adju-

sted from the menu when it is not too

cold outside (warmer than –15 °C).

Decreasing the value of the parameter

increases the freezing of the HR cell.

The winter function of the unit is adju-

sted from the menu in very cold weat-

her (colder than –15 °C). Increasing

the value of the parameter increases

the freezing of the HR cell.

The desired base fan speed (minimum

fan speed) is chosen with the + and

– buttons. Active when week-clock

control is not on. Week-clock control

changes this speed.

The desired maximum fan speed is

selected with the + and – buttons.

Maximum fan speed is on either with

adjustments or always. See Section

3.25. Mode of operation of maximum

speed setting.

The maximum fan speed setting can

be selected to be active either only in

connection with (carbon dioxide and

humidity) sensor adjustments or perma-

nently. The selection is done with the +

and – buttons.
