6.4.2.7 External temperature sensors
An extract air duct temperature sensor, TBLZ-1-76, can be con-
nected to the air handling unit’s control circuit card. See separate
instructions for installation.
Up to four external room temperature and/or outdoor tempera-
ture sensors can be wired to the air handling unit’s control circuit
card. The TBLZ-1-24-2 room temperature sensor or TBLZ-1-24-3
outdoor temperature sensor accessories should be used. See
separate installation instructions.
The sensor can be selected to control only intermittent night
heat and/or summer night cooling (the AHU is then controlled
during the daytime in response to signals from the internal
sensor inside the AHU).
Locate the temperature sensors at suitable places to obtain rep-
resentative readings.
The air handling unit is controlled in response to a computed
mean value of the temperature sensors' readings, alternatively in
response to signals from the temperature sensor that measures
the lowest or highest value.
As an alternative, a temperature reading can be transmitted to
the air handling via communication from e.g. a main system.
The same provision is available for room sensors for the Xzone
function.

Neutral zone
6.4.2.6 Neutral zone
The neutral zone prevents the cooling and heating systems from
counteracting each other.
The preset neutral zone is added to the set point for heating and
the sum of these provides the set point for cooling.
When extract air regulation is active, the supply air set point is
not affected. The neutral zone has no effect if the unit is operat-
ing in the ERS regulation mode.
