1)
A water solution of up to 35 % of propylene-glycol or ethylene-glycol can be used as secondary medium.
Use of other substances is not permitted or the manufacturer of the device must be consulted prior to use.
Requirements regarding water quality are listed in the installation manual in the chapter “Preparation of
the Hydraulic System”. The requirements must be taken into account!
2)
COP (Coefficient of Performance) is a card for performance efficiency of the device, the heating number
which is a quantity without unit. Computer-wise COP is the ratio between the energy gained - heat (in
cooling it is heat taken away) and electrical energy needed for the functioning of the device.
3)
EER (Energy Efficiency Ratio) is an abbreviation for the coefficient of the cooling energy efficiency.
Mathematically EER is the ratio between the effective cooling power and effective electrical power in [kW].
4)
With the cable we have taken into account laying B2 from the table A.52.4 – IEC 60364-5-52. The cable
in the installation pipe is fixed to the wall. The dimensions of the electrical cables must always be checked
or determined by the designing engineer of electrical installations.
4*)
With the cable we have taken into account laying C from the table A.52.4 – IEC 60364-5-52.
The
cable in the installation pipe is fixed onto the wall. The dimensions of the electrical cables must always be
checked or determined by the designing engineer of electrical installations.
5)
Joint maximal load (circulation pumps, electronic valves ...) which can be connected to or powered by the
internal unit, must not exceed 500 W. Higher consumers (i.e. pumps) should have their own supply.
