6.4.15 Humidity
If the functions Dehumidifying regulation and Humidifying are
activated at the same time, Dehumidifying regulation has prior-
ity and the possible settings for Humidifying are limited to being
the same or lower than the setting for Dehumidifying regulation.
There is a delay of 5 minutes between Dehumidifying regulation
having stopped and Humidifying starting up (ande vice versa).

6.4.15.2 Humidifying
Evaporative humidifi cation (On/Off)
This function is suitable together with an evaporative humidifi er
(not Swegon).
The function requires the TBIQ-3-1 IQlogic
+
module accessory
and one TBLZ-31-2 humidity sensor. See separate installation
instructions. Install the humidity sensor in the extract air duct (or
in the premises), see drawing.
The humidity in the extract air duct (the premises) is regulated
between adjustable start and stop limits.
Steam humidifi cation (0 - 10V)
The function is appropriate for operation together with a steam
humidifi er (not supplied by Swegon) and is a variable control sys-
tem via 0-10 V control signal, as well as a contact function which
interlocks the humidifi er if the air handling unit stops, if Summer
night cool is used or if the humidity in the supply air exceeds the
set point by more than 10%.
The function requires the TBIQ-3-1 IQlogic Plus module acces-
sory and one TBLZ-31-1 humidity sensor accessories (for supply
air regulation) or two TBLZ-31-1/2 humidity sensor accessories
(for extract air regulation), see separate installation instructions.
Install the humidity sensors in the extract air duct and the supply
air duct respectively. See drawing!
The function keeps the humidity level constant in the extract air
duct (the premises) by regulating the humidity in the supply air.
In order to prevent the humidity in the supply air from being too
high, it is restricted to a maximum limit.
Alternatively the humidity in the supply air duct can be kept con-
stant by selecting a regulating humidity sensor in the supply air.
The set point cannot be set higher than the max limit. If the
dehumidifi cation function is activated, the max limit cannot be
set higher than the set point for dehumidifi cation.
