(d) Modulating Demand Signal Supplied by Others – A signal that is a linear demand
signal that rises on need for humidity can be used in conjunction with NORTEC
humidifiers. See features section for a list of which models can accept which
signal)
D.
OUTDOOR TEMPERATURE SETBACK
(1) The outdoor temperature setback sensor is used to prevent condensation on windows
or other surfaces that are adjacent to outdoor air. This sensor can be used in
conjunction with the NORTEC controls mentioned above (both the on/off and
modulating demand signal controllers) The sensor allows the controller to override the
set point to prevent the humidifier from humidifying when condensation could be
possible. (See Figure 29.) Locate the temperature sensor near the fresh air intake. This
will ensure accurate representation of the outdoor air temperature.
E.
TRANSDUCER SENSORS
(1) Transducer Sensors are signals sent back to either a controller or back to the
humidifier. Limited models can accept a direct transducer signal. (See features section
for each specific model) The sensors include:
(a) Wall Mounted Humidity Transducer – Sensor, output of 2-10 VDC, range of 0 to
95% rh.
(b) Duct Mounted Humidity Transducer – Sensor, output of 2-10 VDC, range of 0 to
95% rh.
(c) Transducer Sensor By Others – Humidity sensors that rise linearly with the sensed
rh in the room.
