Figure 6 DIP Switch Settings of Analog Output Models
DIP Position Setting
1 Non-metric Non-metric units (°F).
Metric Metric units (°C).
2 Td Td (dewpoint) as humidity parameter on display and
analog output. Sets analog output scaling
to -20 ... +55 °C.
RH RH (relative humidity) as humidity parameter on display
and analog output. Sets analog output scaling to
0 ... 100 %RH.
3 0...5V 0...5V analog output (both channels).
0...10V 0...10V analog output (both channels).
4 Relay On Relay enabled.
Relay Off Relay disabled.
5 Relay High Relay closed when measurement above setpoint.
Relay operation is linked to RH on HMW93, and T on
TMW93.
Relay Low Relay closed when measurement below setpoint.
6 Not used
7 Not used
8 Custom Configuration through service port only.
DIP Configuration by DIP switches only.
NOTE DIP switch 2 does nothing on TMW92 and TMW93.
NOTE If DIP switch 8 is set to Custom, the transmitter ignores all other DIP
switch settings. In custom mode the transmitter uses settings that are
configured in software using the service port.
