Sensor settings
Two HS-91 humidity sensors can be connected to the DZR-45. It is also possible to
connect 1 HS-10 humidity sensor to sensor input 1, instead of an HS-91.
Select the correct type of sensor as follows:
Sensor settings menu -> sensor 1 -> sensor type setting.
If desired, an offset can be defined for the sensors.
Sensor settings menu -> sensor 1 and sensor settings menu -> sensor 2.
Sensor selection: Select the sensor (1/2) that controls each hygrostat (1/2).
Hygrostat (1/2) -> Sensor selection.
General hygrostat operation
The hygrostat uses a sensor to measure current air humidity in an area. The measured
value and the configured air humidity will be used by the hygrostat to implement a
humidifier or de-humidifier so the required value can be achieved.
The hygrostat features various settings. Firstly, the appropriate hygrostat mode
must be selected for the application in question, after which the other settings can
be configured.
Sub-configuration
Mode
Hygrostat:
Standard hygrostat function with set value.
Hygrostat 1/2 -> humidity set point.
Capacity:
Provides a fixed output value.
Hygrostat 1/2 -> Capacity.
Hygrostat / Capacity: The output will act as a hygrostat below a set
temperature. Above this set value, the output will
be defined by the capacity value.
Hygrostat (1/2) -> Temperature. Selection.
Capacity / Hygrostat: The output will act as a hygrostat above a set
temperature. Below this set temperature, the
output will be defined by the capacity value. The
temperature setting can be adjusted as follows:
Hygrostat (1/2) -> Temperature. Selection.
Dead zone: A dead zone is an inactive, neutral area.
A dead zone of 2% and a humidity setting of 50% results in a neutral area
of 49 – 51%. The dead zone is often used to prevent oscillations.
Bandwidth: The bandwidth can be set in:
Hygrostat (1/2) -> (De)humidification -> (De)humidification bandwidth.
The bandwidth monitors the reaction speed of a humidifier between
1 and 20% around the setpoint.
Minimum: A minimum can be set for any output. This can be set as follows:
Hygrostat (1/2) -> (De)humidification -> Minimum (de)humidification
settings (0-99%).
