Auxiliary Controls (also known as Aux Control) are a cross between an Equipment Control and an Alarm
Control. Aux Controls allows you to control any Equipment or Alarm Output based on a specified environmental
condition. Aux Controls are often used as a flexible Alarm control, as they can turn on an Output if an alarm
type condition occurs. Another way to look at Aux Controls is as a Conditional Equipment Control. Meaning, if
some specific condition occurs in your greenhouse, then activate certain Equipment.
Aux (1)
You can have up to 8 Aux Controls. Use the + or – buttons to set which Aux Control you want to setup.
Channel (3)
You can assign Aux Control to control any Output Channel (1-12 and either or both Alarm Output(s)). Aux
Control can operate as an override to an equipment such as:
Example 1
Channel 1 is a single channel device (ON/OFF, CO2, Light, etc) - if channel 1 passes some threshold then
activate channel 5
Example 2
Channel 1 is set as a two channel, proportional, device (Vent, Mixvalve, Curtain) – if channel 1 goes above 50%
then de-activate channel 7
Select the conditional Control
To select the conditions, adjust the sensor input, greater than or less than, and the value under which the
condition will trigger at. Use the + or – buttons to choose adjust these values.
Select Condition Time
The specified condition must occur for the specified time in order to activate the Output Channel.
Hold Time
Once the condition is no longer met, the Hold Time will keep the channel active for the specified amount of time.
In the example screen above, if the Temp2 (Temp Probe 2) measures a temperature below 59
°
F for 30sec
then Output Channel 3 will turn on. Channel 3 will then remain active for 10 minutes or until
the temperature
rises above 59
°
F.
This is useful to prevent cycling of equipment.
