Dhu OALK
Dehumidification outside air
temperature lockout
Default value = -40°F (-
40°C)
Outside air temperature under which the dehumidification sequence is
disabled.
Only valid if an outdoor air sensor is connected at the humidistat or a network
value is transmitted to the humidistat.
From –40°F up to 122°F (-40°C to 50°C)
HL Hyst
High Limit hysterisys
Default value = 5% RH
High Limit control hysterisys.
Used only if sequence uses 2 position humidity controle
2 = 2Pdh and 4 = 2Phu2Pdh
From 2% RH up to 20% RH
cal RH
Humidity sensor calibration
Default value = 0 %RH
Offset that can be added/subtracted to actual displayed humidity by ± 15.0
%RH.
This calibration applies to the internal humidity sensor if no remote humidity
sensor is connected. This calibration applies to the remote humidity sensor
when one is connected.
From –15% RH up to 15% RH
cal OS
Outside air temperature
sensor calibration
Default value = 0.0 °F or °C
Offset that can be added/subtracted to the displayed outside air temperature
± 5.0 °F ( ± 2.5 °C )
RH LT
Reset RH lower outside
temperature setpoint
Default value = -20°F (-
29°C)
Minimum outside air temperature for RH setpoint reset.
Only valid if an outdoor air sensor is connected at the humidistat or a network
value is transmitted to the humidistat. See RH HT & RE Sp.
From –40°F up to 15°F (-40°C to –9.5°C)
RH HT
Reset RH higher outside
humidity setpoint
Default value = 32°F (0°C)
Maximum outdoor air temperature for RH setpoint reset.
Only valid if an outdoor air sensor is connected at the humidistat or a network
value is transmitted to the humidistat. See RH LT & RE Sp
From 20°F up to 55°F (-6.5°C to 12.5°C)
RE Sp
Reset humidity setpoint
Default value = 20% RH
The RH setpoint will be reset from the user setpoint to this value when the RH
LT outside air humidity value is reached.
Only valid if an outdoor air sensor is connected at the humidistat or a network
value is transmitted to the humidistat. See RH LT & RE HT.
From 10% RH up to 90% RH
HL Sp
RH High limit setpoint
Default value = 85% RH
High humidity limit in the supply.
Only valid if a 0-5 Vdc sensor is connected at the humidistat – otherwise this
feature is disabled automatically.
From 50% RH up to 90% RH
