Why does my equipment still run when the output is at 0 percent?

Can a current sense input be paired to an output?
Yes, a CurrentSense-2 can be configured to an IN-4 input. That input can then be assigned to an RM-4 output. This allows for a high alarm shut-off to be enabled for that output, similar to what an RM-2 is capable of.
Does a low or high temperature alarm affect the output?
No. If there is a low or high temperature alarm the, alarm contacts will change state but the variable output will continue to operate according to the programmed settings.
Why do I measure full voltage output when the control says it should be less?
The control and expansions need to have a load connected for the triac to give a correct output. If there are no mats (load) connected to the triac output, the output will always read full voltage, no matter what you set the control to. As soon as ...
What modules do I need to run HVLS fans on a VFD?
In order to control a VFD, you will need 1 0-10v output from a VDC-4, as well as 1 follow relay from a RM-4 which controls the VFD's start/stop contact.
Can I use misting, fogging, and soaking in a THI controlled equipment group?
Yes! THI misting/fogging/soaking looks exactly the same as in a cooling equipment group, only you will have THI values as the low/high/max setpoints rather than temperature values. There are three videos explaining the three modes available in the ...
