•
GHE
operation
- switching the GHE control module on or off. If GHE is not available in the system, disable GHE
support, by setting the parameter to
No,
so that the control algorithm is not affected by the absence of the module.
•
Type
of
re-heater
- activating or deactivating the type of the re-heater in use with the
None
set-point.
•
Re-heater
support
- activation or deactivation of the -re-heater operation (electric or water heater).
•
SM1
damper
support
- activation or deactivation of the SM1 damper support (located between the duct that
connects the air supply and air exhaust).
•
Radiator
support
- activate or deactivate radiator control. Freon or water cooler is supported.
•
Bypass
damper
2
support
- activation or deactivation of bypass damper 2 operation during the process of air control
and recovery.
•
SM1
settings
- service settings for the SM1 butterfly valve. Setting the minimum and maximum control values for
the SM1 butterfly valve, below which the control algorithm will not work, using the
SM1
minimum control and
SM1
maximum
control
parameters.
•
Configuration
of
potential-free
contacts
- settings related to the assignment of functions to potential-free contacts.
•
The actuators corresponding to the dampers in use will be controlled based on the ON-OFF principle, which
corresponds to the damper position in the Open-Close position.
CAUTION!
It
is
recommended
to
use
a
damper
with
an
actuator
on
the
inlet
side,
which
will
cut
off
air
flow,
when
the
controller
is
switched
off.
The method of connecting damper actuators to the controller terminals is shown in the wiring diagram.
Hardware
configuration
of
recuperator
inputs
Setting the configuration related to the recuperator inputs.
•
Air
quality
sensor
- activation or deactivation of an air quality sensor. The supported sensors include:
Analogue
CO
2
sensor,
which
allows you to control concentration of CO
2
in the rooms,
Analogue
humidity
sensor,
which allows you
to control the level of humidity in the rooms, and a
Digital
sensor
.
CAUTION!
The
transfer
of
moisture
from
the
exhaust
air
to
the
usually
dry
supply
air
is
only
possible
with
a
rotary
recuperator
or
an
enthalpy
heat
exchanger.
The connection of the CO
2
and humidity sensors must be carried out, according to the wiring diagram.
•
Heater
thermostats
- settings related to the thermostats in the pre- and re-heaters. Determine the rest state for the
thermostat contact corresponding to the heater in use, and set the
Pre-heater
thermostat
and
Re-heater
thermostat
parameters to
Normally
Open
or
Normally
Closed
.
•
Settings
for
R1/R2
inputs
- settings related to the operation of the R1/R2 digital inputs.
The settings related to the operation of digital inputs to change the air flow demand for fans, in the constant control mode,
are made in the
Hood
mode
settings
parameter group.
•
Hood
mode
support
- activation and deactivation of the control corresponding to changing the demand for air flow,
based on the readings of signals from the R1 and R2 digital inputs.
•
Logical
status
of
the
R1,
R2
inputs
- the
Normally
Open
or
Normally
Closed
logical states corresponding to detecting
air flow demand in R1, R2.
•
Supply
air
fan
controlled
with
R1,
R2
and
Extract
air
controlled
with
R1,
R2
- setting the percentage change of the
supply air fan and the extract air fan speeds based on the R1 and R2 signals. Setting a value above “0” increases the
air flow rate, while any value below “0” reduces the air flow through the fan.
Fan
settings
This menu contains fan settings available to the installer, in which you can set the minimum and maximum fan control
values and a delay in stopping the fans, after the electric heaters were activated.
•
Min
and
Max
supply
air
fan
control
- corresponding to the minimum and maximum control values that can be set
in the installed supply air fan. The setting should be selected, depending on the fan power.
•
Min
and
Max
extract
air
fan
control
- corresponding to the minimum and maximum control values that can be set
in the installed extract air fan. The setting should be selected, depending on the fan power.
•
Air
supply
fan
stop
delay
- delay in stopping the air supply fan, after the electric pre-heater stops working.
•
Minimum
outside
temperature
- the minimum outside temperature at which the recuperator is permitted to
operate. The recuperator will not be able to operate below the threshold set in the
Permitted
from
min
outside
temperature
parameter. In addition, the
Min
outside
temperature
parameter makes it possible to set a value of
temperature below which the recuperator will not be allowed to work, also taking into account the value of the
difference from this temperature threshold set in the
Hysteresis
of
min
outside
temperature
.
CAUTION!
The
outside
temperature
is
measured
by
a
temperature
sensor
at
the
inlet
to
the
air
intake.
