The sensor is supplied with 0 - 10VDC linear analogue outputs for Out(1), Out(2) and Out(3) (see
Table 1). Alternative output ranges can be configured via PC software UIP (version 5 or later). See
information at
senseair.com.
Out1/Out2/Out3
e.g
Each output consists of four blocks. Each block has nine source options.
OUT1 (OUT2/ OUT3/(Relay)) is the
largest (Max of a, b , c) demand from Proportional-bands.
OUT1=Max of Out1_a/ Out1_b/ Out1_c minus (sub) Out1_d
5V (Out1_c)
– 0V (Out1_d Disabled) = 5V
=> OUT1=5V
The (e.g.) VAV valve opens from minimum set-point position with full opened state at the maximum
set-point.
