9.1 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 first stop the air handling
unit before doing so.
9.2 Temperature Regulation
Select ERS Regulation, Supply air regulation or Extract air
regulation.
If ERS Regulation is selected, select between 1 and 2.
Control sequence for ERS regulation and Supply air regu-
lation:
1. The temperature efficiency 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 flow rate.
A neutral zone can be preset, which allows a lower supply
air temperature setpoint before regulation to a lower flow
rate begins. See 8.3.4
When the supply airflow 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 airflow 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 lea-
kage spots such as doors and windows. This outdoor air
will then be heated by the ordinary heating system of the
premises.
Downspeed regulation to lower the airflow rate occurs
from the current preset flow (high speed or low speed),
down to half of this flow rate. The degree of regulation
to a lower rate is also limited by the min flow setting of
the unit. When preset flow for low speed is near the min
flow rate, the effect of this regulation to a lower rate will
be small.
Control sequence for Extract air regulation:
1. The temperature efficiency of the air handling unit’s
heat exchanger is modulated to provide max. heat
recovery.
2. After that, the re-heating coil, if installed, will begin
to generate heat.
Important! The appearance
of the menus varies
depending on the type of air
handling unit and functions
selected.
