AIR DISTRIB.
– [they are a active only for EC fans] Difference between intake air and extract air creates high pressure or
underpressure in rooms. Generally installation supplying the air from the external inlet has got different resistances than power
installation of exchanger GHE. So that it is possible to correct the pressure for the external inlet and exchanger GHE in the
controller. To do some corrections in external input probe one should turn off the GHE at first. Later go to the "CORRECT.." option.
In window the high pressure sign
∆
pout
should be visible. It means that correction is related to external input. In the right column
there are particular rotation's deviation from the nominal value, measured in [%]. Positive values stands for work with high pressure
and negative ones the underpressure. The values of all corrections can be changed in range of -10% ÷ +25%. During the correction
controller automatically change the gears matching them to the current corrected value allowing to current pressure measurement.
Correction for GHE is made in same way. One has got to the GHE setting and set it for ON. Again, one need to go back to the
CORRECT… option Now in the window there is visible the following sign
∆
pghe
- standing for the GHE mode of correction. Edition
is the same as above.
MOTORS
– type of the motors, which are mounted in recuperator. Option available:
•
Type :
AC
- motors powered by 230VAC
•
Type :
EC
- motors powered by 230VAC but controlled by 0÷10VDC signal
•
Speed number
:
[
1÷5
] – number of speeds (gears) For EC fans it can be taken 5 value and for AC fans it depends on
their construction.
DEFROST
– configuration procedures for protection against freezing of the heat exchanger.
•
Mode:
OFF
– the procedure is totally off and system doesn't react for any signal. This solution can be use in case that
the recuperator is provided with internal defrosting system, for ex. supply air ventilator is powered by pressostat switch
or when the manufacturer of recuperator gives a guarantee that this doesn't frost.
•
Tout <
[-1° to -15°C] – Below that temperature the frost process can occur
•
Preheater P/N
[-3° to -7°C] – the temperature of operating the preheater as a frost protection. Relay connector
marked (
A-B
) can be used to direct switching of preheater. The maximum power that can be connected directly
cannot exeed 0.8kW. In case of bigger power you should use external relay. For such a operation one need to choose
Preheater P ….
(active relay turn the heater on) In case of using the heater with thiristor / triack controller for. ex.
ENO.T one need to select the
Preheater N ….
(active relay turn the heater off)
For measurment of the air temperature behind the preheater we use GHE sensor (
Tg
).
BACKLIGHT
– controller is provided with backlight display LCD. The intensity can be set by user.
•
Config :
CONST
or
AUTO
– in AUTO option after turning the backlight off the short pressing screen / touch pad
causes its rebooting.
•
Level:
[0 ÷ 100%]
– the value of backlight intensity
HEATER
– the controller can drive heater using 0-10VDC signal with PI algorithm.
•
Config :
OFF
or
HE
or
HW
– it can be selected what type of the heater (electric HE or water HW) has to operated by
controller. In case of water heater the frost protection procedure can open valve totally. To input WE5 one needs to
connect the thermostat's connectors protecting the heater.

•
Kp –
[1÷100%]
its a gain factor of the proportional part
•
Ti –
[10÷990s]
its a integration time
•
TU:
[15 ÷ 50°C]
the temperature which should be maintained by heater Sensor
Ts
(supply air) should be installed
behind the heater
