TEMPERATURE SENSORS OPERATING PRINCIPLE
IComplete with controller is NTC thermi-
stor on the 20cm wire. It can function
as a one sensor if there isn’t required an
additional casing of sensor. The second
sensor isn’t supplied with termostat.
IThe sensors can be extended to any
length but we should remember that
extension above 10m may cause a de-
viation of measurement with each me-
ter and falsifying results. Therefore, for
distance above 10m device has to be
calibrated. Sensors have to be extend
of wires:
» to 50 meters 2x 0,75 mm2
» above 50 meters 2x 1,50 mm2

In the controller we have to set three time
values:
Testing break - value in minutes spe-
cifying, at what time do the measuring
test. This value depends on devices,
which ‘receive’ heat or cold and more
precisely depends on how often the
temperature conditions may change
in this device. In the typical size of GHE
(typical family house) this value is most
in the range of 10 ÷ 30 minutes.
Testing periods - value in seconds spe-
cifying, how long device has to work
before reading of sensor reaches the
appropriate level of temperature (star-
ting period, starting delay ). Testing pe-
riod is set separately for each device.
In case of installation of GHE the rst devi-
ce is directly external inlet probe and sensor
has to be placed near to the inlet probe (di-
rect measurement of external temperature).
Testing period of this device should be set
to 0 (there isn’t any delay, the reading is cur-
rent). The second device is GHE. Delay of this
device should be set to optimal value for the
GHE - mostly it’s time to move air through
the GHE (it depends on length and size of
GHE). For the typical size of GHE (for typical
family houses) this delay is in the range of 20
÷ 120 seconds.
Depending on the mode in which the con-
troller operates (heating or cooling), device
chooses warmer or colder device.
The controller is intelligent. It means that it
remembers readings and change the tem-
peratures on the both devices. For example:
when controller during data analysis deter-
mines that there is probability of more favo-
rable temperature conditions on the second
device than currently used device, may be

EXAMPLE OF OPERATING
to be higher than the air temperature
from the GHE, the controller will switch
devices so that the air was taken from
the external inlet probe (it happens
immediately because testing period of
inlet probe is set on 0 seconds but inc-
luding hysteresis).
If the outside temperature falls below
the last memorized temperature which
was on the GHE or from the appropriate
algorithm, the controller„suspects”that
air temperature from the GHE will be hi-
gher than outside temperature or 15mi-
nutes (testing break)have passed since
the last switching air dampers. The GHE
is turning on (on thirty-seconds testing
period). After the test, the controller
decides from where take the air.
IIn our oer are available air dam-
pers with actuators with dierent
cross-section.
earlier testing of the second device.
Typical GHE installation. The controller is de-
signed to decide from where take the air:
from the GHE - there is closing of the air
damper with actuator from the exter-
nal inlet probe. The air damper with ac-
tuator is opening from the GHE simul-
taneously and the controller starts the
GHE fan.
from the external inlet probe - there
is closing of the air damper with ac-
tuator from the GHE and turning o
the GHE fan. The air damper with ac-
tuator is opening from the inlet probe
simultaneously.
Testing period of inlet probe is set on 0 se-
conds (current measurement without delay).
RT sensor is placed near external inlet probe
so as to measure the outside air temperature
(shady, sheltered from the wind and moistu-
re place).
Testing period of GHE is set on 30 seconds
(this is air ow from the onlet probe of GHE
to recuperator). FT sensor is placed in the
ventilation duct from the GHE before the
recuperator.
Testing break is set on 15 minutes.
Heating mode is set (selection of a hotter
heat source). In the summer the controller
by pressing single button switches onto the
cooling mode to cooling the building.

EXAMPLE OF CONTROLLING WATER HEAT EXCHANGER
IB-Tron 1000 GWC controller measures two temperatures: outside temperature (by RT sen-
sor) and air temperature after passing through the heater, when water circulation pump is
turned on (glycol or brine), by FT sensor. Measurement of the outside temperature (RT) is
current, measurement of air temperature (FT) at the switching on heater has to be cyclic.
Testing period should be as short as possible but has to ensure proper stabilization of the
air temperature after passing through the heater (installation which leads water, heater and
air from the heater has to warm up).
If the controller after this testing period recognizes that favorable temperature conditions
provides water heat exchanger, the pump still works and measurement of FT temperature
is current. Measurement of RT temperature is current too, so if favorable temperature con-
ditions are at the external inlet probe, the P1 pump will be turned o.
If favorable temperature conditions after testing period are still at the external inlet probe,
P1 pump is turned o. The pump is again turned on only after testing period.

WORK MODE HYSTERESIS
KEYBOARD LOCK
TEST PERIOD AND TEST BREAK
The controller can work in two modes:
Heating mode (selection of warmer
source)
Cooling mode (selection of colder
source)
To change mode please press the button:
Hysteresis means a delay in switching on/
switching o the device. If it’s higher value
of the hysteresis, controlled device performs
less cycles (e.g: air dampers) - therefore vita-
lity of the device increases.
In normal conditions it’s recommended to
set hysteresis value to 1ºC. Value setting of
hysteresis depends on where is the measu-
rement (e.g. for liquid suggested is higher
hysteresis).
To change value of hysteresis please:
To protect controller from unwanted change
settings, you can lock controller keyboard.
When keyboard lock is activated, on display
is visible a padlock symbol and keyboard do-
esn’t respond to pressing keys.
To activate/deactivate keyboard lock please:
To set the appropriate testing periods for RT
and FT and testing break please:
