6.4.2 Temperature
N.B.! If the entry of new temperature settings involve large
changes, you should fi rst stop the AHU before you enter the new
settings.
Specifi c temperatures, such as set points, should be specifi ed
in °C or °F, whereas displacements, deviations and differentials
should be specifi ed in K (Kelvin).
If only GOLD SD supply air handling units are installed, they
require an external room sensor for ERS, ORE and extract air
regulation.

All the relevant values can be read here. Used for performance
checks.
6.4.2.2 Settings
ERS Regulation 1
ERS regulation refers to Extract air temperature-Related Supply
air temperature regulation. This means that the temperature of
the supply air is regulated in relation to the temperature of the
extract air.
Under normal circumstances, the supply air temperature is
regulated to be a few degrees lower than the extract air tem-
perature. In this way, the heat exchanger will provide optimal
performance, and this means excellent operating economy.
ERS control is suitable for use when there is surplus heat in the
premises generated e.g. by machinery, lighting or people, and
the premises have supply air diffusers suitable for discharging air
below room temperature.
ERS Regulation 1
The control unit regulates the ratio between the supply air and
extract air temperature according to a factory-preset curve.
See the diagram to the right.
The step in the curve, breakpoint and differential can be
changed.

Factory setting means:
If the extract air temperature is below 22 °C (breakpoint), the
supply air temperature set point will be automatically regulated
to be 3 K (diff.) lower.
If the extract air temperature is above 22 °C, the supply air tem-
perature set point will constantly be 19 °C (step 2).
