Note:
For Zone Master and Slave units, you should set all weather station sensors (OutT, OLight, WindSpd,
WindDir, and Rain to
Remote
. Setting the weather station sensors to Remote means the Slave unit or
Zone Master will get their weather station data remotely from the Site Master.
PREV
and
NEXT
keys move the cursor from one input selection to the next. Using the
+
and
-
keys you can
select which one of the input channels to assign to your sensors. Note that the allowable choices vary from one
type of sensor to another. If any given sensor is not present,
None
should be selected. The
Software
choice is
useful for testing and debugging if you just want to force the reading to a particular value. The software value
can be modified through the Calibration Inputs screen below.
The
Backup Sensor
is an optional way to tell the iGrow 1800™ which sensor it should default to in the case of
a failure on the InTemp temperature sensor.
Note:
For the Backup Sensor to be used, to must be Enabled. See also
Fallback Settings
below to Enable the
Backup Sensor.

Sensor:
None
Operating Period:
24 Hour
There are two accumulators that can be used. They can be used for the outdoor temperature influence
on the indoor temperature setpoint or in conjunction with auxiliary controls. Any of your sensors can be
utilized for the accumulation purposes.
There are two operating period options:
24 Hour
or
Setpoint Change
: If the 24 hour period is selected,
then the accumulator begins at 12:00 AM and ends the accumulation at 11:59 PM. The data is logged
and time stamped and the accumulator is reset. If the Setpoint Change option is selected, then the
accumulator begins at the start of a setpoint interval and the accumulator is reset at the end of the period.

option is for calibrating the outside light sensor (above) or a CO2 sensor (below), if
you have one. The
Raw Value
is the actual reading from the sensor. The
Factor
for the light sensor is
the multiplier adjustment. Use the
