Control Settings Menu
Control Settings menu is discussed below. Refer to the structure of the tabs in
.
Basic Tab
–
Source:
allows you to select the source of incoming control/hu
-
midity signal to the humidifier.
Options:
Analog
– signals from analog sensors or
humidistats connected to the humidifier's
low voltage terminal block.
Modbus
– signals from BMS via the Modbus
communication protocol.
BACnet/IP
– signals from the BMS via the
BACnet/IP communication protocol.
BACnet/MSTP
– signals from the BMS via
the BACnet/MSTP communication protocol.
LonWorks
– signals from the BMS via the
LonWorks communication protocol.
Factory setting:
Analog
–
Control Channels:
select one or two control signals to control the
humidifier.
Options:
Single
– single control signal.
Dual
– two control signals (typically a con
-
trol, plus a high limit signal).
Factory setting:
Single
–
Control Mode CH
1
:
select the general control mode for the
incoming control signal.
Options:
Demand
– signal from an external controller.
RH P
– uses the internal (proportional) controller
to interpret the sensed humidity into a demand.
RH PI
– uses the internal (proportional-
integral) controller to interpret the sensed
humidity into a demand.
On/Off
– control signal is from an external
On/Off humidistat.
Factory setting:
Demand
–
Limiter Mode CH2:
only appears when control mode is set to
double. Allows you to set the limiter signal type.
–
Signal Type Channel
1
:
select the signal type of the incoming control
signal.
Note:
This setting is ignored if signal
is not set to "Analog".
Options:
0-5V, 1-5V, 0-10V, 2-10V,
0-20V
, 0-16V, 3.2-
16V, 0-20mA, 4-20mA
Factory setting:
0-10V
–
Signal Type Channel
2
:
select the signal type for the high limit
signal.
Note:
This setting is ignored if signal
is not set to "Analog".
Channel 2 applies only when
is set to "Dual".
Options:
0-5V, 1-5V, 0-10V,
2-10V
, 0-20V, 0-16V, 3.2-
16V, 0-20mA, 4-20mA
Factory setting:
0-10V
