| Information about the residual risks
From Systemair every heating coil for hot water is provided with a little pipe at the collection pipe for the return water.
This little pipe is prepared for the installation of the above mentioned temperature sensor for the transmission of the re-
turn water temperature to the controller.
K.6.17 Systemair Control Panel - SCP
The separate cable-connected (10m) hand terminal with display and buttons – the Systemair Control Panel is always
necessary for the normal handling and programming, because the main Systemair E28 controller is without display and
buttons.
K.6.18 Cooling recovery
If the extract air temperature is lower than the outdoor air temperature, and there is a cooling demand in the rooms,
the cooling recovery will be activated by reversing the heat exchanger signal. The signal is increased to the cooling re-
covery by increasing cooling demand.
K.6.19 Free cooling
A temperature sensor has been installed inside the unit in the outdoor air entrance. If the outdoor temperature after
midnight is below the room temperature set point and the actual average room temperature is above the set point
temperature, the fans start during the summer to cool down the building during night hours.
K.6.20 Alarm signal
By alarm there are 24 V DC on terminals in the cabinet. Lamps and cables are not available from Systemair.
K.6.21 Heat recovery
The heat recovery capacity is controlled by modulating speed of the rotor.
K.6.22 Frost protection – plate heat exchanger
Signals from a temperature sensor mounted in the airflow after the plate heat exchanger are transmitted to the control-
ler for frost protection of the plate heat exchanger.
K.7 Commissioning
When the installer has completed the installation and wants to hand over the finished installation to his customer for
payment the commissioning protocol can be the written receipt for the full ended job. Fill in the blank spaces and sign
the proposed commissioning protocol that is Annex 13, or fill in the Word-file with a Commissioning Protocol that is in-
cluded on the DVD delivered with the unit.
K.8 Unit in hipernation
When the unit is in hipernation after the installer has completed the installation, the unit must be in operation for 10 —
15 minutes every day.
L Information about the residual risks
L.1 Unit casing
L.1.1 Design of the machine to make transport safe
Hazards/dangerous area:
• Incorrect handling during transportation may cause that the unit is dropped.
Dangerous incident:
• If a person is hit by a unit that is dropped, this could in unfortunate circumstances lead to irreversible injury or death.
Claim for reduction of danger:
• Correct handling during transportation is described in this manual. If lifted by fork-lift truck the forks of the truck
must be sufficiently long. Safety measures are also described in this manual by use of crane. Information about
weight of each section is also visible.
