10 FUNCTIONS

10.1 Temperature

Basic functions can be set at INSTALLATION LEVEL
and values are read and set at USER LEVEL.
IMPORTANT! If you intend to substantially alter the tem-
perature settings, you should fi rst stop the air handling
unit before doing so.
10.2 Temperature Regulation (Control)
Select ERS Regulation. Then select ERS Regulation 1 or 2.
Control sequence for ERS regulation:
1. The temperature effi ciency of the air handling unit's
heat exchanger is modulated to provide max. heat
recovery.
2. After that the air heater, if installed, will begin to
generate heat.
3. If a downstream heating coil is not installed, or if the
its output is not adequate, the supply air fan will be
automatically and variably downspeed-regulated to
convey air at a lower fl ow rate.
A neutral zone can be preset, which allows a lower supply
air temperature setpoint before regulation to a lower fl ow
rate begins. See 10.3.3.
When the supply airfl ow is regulated to a lower rate, the
heat exchanger will have "excess heat", i.e. warm extract
air, giving it capacity to maintain the supply air tempera-
ture required.
As the supply airfl ow is regulated to a lower rate, the air
pressure in the premises will become negative and this
will instead cause outdoor air to be sucked in through
leakage spots such as doors and windows. This outdoor
air will then be heated by the usual heating system of the
premises.
Downspeed regulation to lower the airfl ow rate occurs
from the current preset fl ow (high speed or low speed),
down to half of this fl ow rate. The degree of regulation
to a lower rate is also limited by the min fl ow setting of
the unit. When preset fl ow for low speed is near the min
fl ow rate, the effect of this regulation to a lower rate will
be small.
