Cyclic
ventilation
time
- it is a time interval at which the ventilation cycle is to be repeated, after the unit has
switched to control mode.

Heat
recovery
This menu contains user settings related to bypass and ground heat exchanger (GHE).
Bypass dampers allow diverting external air and bypass the heat exchanger to disable the heat recovery function at high
external temperatures, or when there is a risk of frosting.
•
Cross-flow
heat
exchanger
control
- allows selecting a control mode for bypass dampers. The dampers can be
permanently opened -
Full
recovery (in this case the permanent heat recovery function is deactivated. There is no
risk of frosting of the heat exchanger), or permanently closed - No
recovery
; or they can be controlled by the
Auto
Free-Cooling algorithm (the air inside is cooled to the temperature set by the low temperature of outside air), or
the normal operating algorithm -
Auto
without
Free-Cooling
.
The controller controls the ground heat exchanger (GHE) as part of the ventilation system. Ground temperature of approx.
8
º
C is used to heat up the air in the winter, or to cool the air flowing through the GHE, in the summer.
CAUTION!
In
order
to
operate
the
GHE,
an
external
temperature
sensor
must
be
connected.
The
GHE
control parameter allows selecting an operating mode for the GHE:
•
Close
- the controller closes the damper on the GHE line and cuts off the air flow through the GHE.
•
Close
- the controller opens the damper on the GHE line and opens the air flow through the GHE.
•
Auto
- the controller closes the air intake damper and opens the GHE damper for the intake of air to the recuperator,
through the GHE, when the outside temperature is above the
Winter
opening
temperature,
e.g. in autumn and
winter periods. The controller closes the air intake damper and opens the GHE damper for the intake of air to the
recuperator through the GHE, when the external temperature is below the
Summer
opening
temperature,
e.g. in the
summer. The switching of the dampers depends on the operating status of the controller set by the user.
CAUTION!
The
outside
temperature
is
measured
by
a
temperature
sensor
at
the
inlet
to
the
air
intake.
The additional adjustment settings for the GHE can be found in:

•
Maximum
opening
time
of
GHE
- the maximum time during which the GHE damper throttle can remain opened.
After this time, the GHE regeneration procedure will be started.
•
Recovery
time
of
the
GHE
- regeneration time for the GHE. During regeneration, the GHE damper will remain
closed.
•
Manual
activation
of
regeneration
– manual activation of regeneration, without waiting for the temperature
and time criteria to be met.

General
Settings
•
Alarm
sound
- activating or deactivating the acoustic signal for alarms.
•
Language
- selecting menu language.
•
Date
- setting the date. After entering the date, the day of the week will be set automatically.
•
Clock
- setting the time. Changing the time from the level of any ecoSTER TOUCH room panel will also change the
time in the controller itself.
•
Brightness
- the intensity of display backlight.
•
Keystroke
tone
- activating or deactivating the sound of pressing a key on the touch screen.
•
Software
update
- updating software for the controller module and control panel, by means of a microSDHC
memory card (only), which is installed in the socket in the panel housing, and in the corresponding programmable
devices connected to the controller module.
