MODE
DEADBAND
: Y output used as a Heating O/P, a Cooling O/P or set to act as BOTH a Heating &
Cooling O/P.
: The temperature gap from the controller’s setpoint till the Y produces an O/P
PROB
(portional)
BAND
: The change of temperature over which the Y O/P would increase to 10volts
INT
(egral)
TIME
: Time in minutes that the integral action adds the P only output to itself over the
integral time setting. Note P+I action starts as the output produced by proportional
only O/P exceeds 10%.

Another possible alternative use for the Y1 & Y2 analogue outputs could be for use as an EC FAN time switch
controlled run & speed setting module, the controller could be set to time switch only mode but
with
Y1
(
as
an example
) set
to a
minimum
output
of
50% (which is still
accessible
even in time switch only mode). When
the time switch 1 is ON, Y1 would produce 5v
(EC fan ~ 50%) and
when the time switch turns off the Y1
output w
ould
return
to
0v output.
