User Manual
HRU-SlimAIR
The output to control the geothermal heat exchanger valve, can be configured using
Geothermal Heat
Exchanger Valve Output (#195)
from 0 to1 and disable Frost protection by changing
Frost sensor (#140)
value to 0.
The automatics controls the valve based on the temperature at the outdoor (Temperature 4 outdoor). If
the Temperature 4 outdoor is lower than the
Geothermal Heat Exchanger Outdoor Temperature Below
(#193
)
or higher than the
Geothermal Heat Exchanger Outdoor
Temperature Above (#194)
the valve will be opened and the air
going to the unit will be taken from the ground heat exchanger. If
the temperature sensor (Temperature 4 outdoor) is broken or if the
above condition is not met the valve will remain closed.
Values
Geothermal Heat Exchanger Outdoor Temperature Below
(#193)
and
Geothermal Heat Exchanger Outdoor Temperature
Above (#194)
are set in deafult mode for 5°C and 25°C. They can be
edited from the service tool and the LCD Display controller.
Functional check:
Temperature 4 outdoor >5°C (#193) and <25°C (#194) valve position HRU-OUTDOOR
Temperature 4 outdoor <5°C (#193) and >25°C (#194) valve position HRU-GHE
6.11 Cooperation with the kitchen hood
The cooker hood can be connected to the MVHR system via the X25 contact on the main board of the SlimAIR heat
recovery units. It is a potential-free contact. Short-circuits of contact inputs will result in an exhaust fan stopping
completely during the period the contact is closed.
In order for the valve to operate correctly, the dumper with
a DM-ML-06-230 electric actuator should be connected
to X28 in the following order:
