N2 Dialer Module—N2 Dialer Module (NDM) 17
The dial command point initiates a dial-out sequence that causes the local NDM to dial
out to remote facilities. Overriding this point to a value from 1-50 causes the local NDM
to dial out to the site corresponding to the number that was configured in HVAC PRO for
Windows. Overriding this point to a value of zero causes the NDM to hang up a phone
connection. When a remote site initiates a call to the local NDM, the dial command
displays a value of -1.
