Problem
Possible Cause(s)
Solution
A connection
cannot be
established to the
controller via
modem.
The analog phone cable is not connected
securely to the controller, PC, and/or wall jacks.
Check all connecti ons and replace the
phone line if damaged.
The phone line is not functional for dial in.
Try dialing the number using a landline
or cell phone to see if the controller
answers. If it does not, connect an
analog phone to the line in place of the
controller and dial the numb er again
using the same landline or cell phone.
The phone should ring if the call is
coming through.
The phone line is in use.
This can happen if the controller is
dialing out to send an email or if
another party is connected to the
controller via modem. Try again later.
The phone number used by the PC is incorrect. Check the phone number you are
dialing.
With a gateway
connection
established, the
Configurator
cannot
communicate with
the controller.
The IP Address being used by the Configurator
is incorrect.
The default IP address for the gateway
connection is 192.168.1.2. In the
Configurator's Connection Window,
click on Advanced and make sure this
is the IP address being used in the
connection attempt.
There is >0.5 gpm
flow through the
flow switch, but a
No Flow Alarm is
active.
The flow switch is not connected properly.
Remove the flow switch wires and short
the + and - terminals on the controller
using a wire jumper. The No Flow
indicator on the display and the No
Flow Alarm should clear. Reconnect
the flow switch wires.
The flow switch is not functi onal.
Stop the flow, remove the flow swi tch
and clear any debris lodged inside. If
this does not help, replace the flow
switch.
There is <0.5 gpm
flow through the
flow switch, but the
No Flow Alarm is
not active.
The flow switch is not connected properly.
Check the flow switch connecti ons in
the controller.
The flow switch is not functi onal.
Replace the flow switch.
The 10-minute delay period has not passed.
The flow signal must b e absent for 10
min before the alarm wi ll activate.
The flow is near the 0.5 gpm rati ng of the flow
switch, resulting in intermittent flow/no flow
indications.
This will cause the 10-minute delay
timer to reset each time flow is
detected, preventing the alarm.
Increase the flow.
