Water inlet temperature of energy recovery ˚C 0 50 99
Water inlet temperature of energy recovery ˚F 32 122 210
Energy recovery water outlet temperature ˚C 0 Depends on 99
application
Energy recovery water outlet temperature ˚F 32 Depends on 210
application
To modify a setting, consult the relevant section in the description of the Elektronikon controller.

The recoverable energy can be calculated from:
RECOVERED ENERGY (kW) = 4.2 x water flow (l/s) x water temperature rise
(°C) In the tables below, typical examples are given, except for the recovered
energy.
