Common Trouble Shooting Issues
Issue
Explanation / Recommended Action
The Boiler Outlet temperature
displayed at the ModSync® does
not match what is shown on the
local boiler controls for 4-20mA
applications.
This is commonly seen on boilers with the
Siemens LMV3 controls. Check that the Outlet
temperature scaling in the ModSync® matches
the scaling in the local boiler controls. The
most common are 0-210F and 0-240F.
The Protonode is not
communicating with the
ModSync® (Rx and Tx are not
flashing)
Check that the Protonode is connected to Port
2 on the ModSync® using the factory supplied
cable. The Port 2 settings on the BMS Config
page should be set up for a node address of 2
and baud rate of 19200.
The Boiler is tripping on its high
limit while under ModSync®
control.
Check that the Maximum setpoint plus any
deviation is set at least 10F below the high
limit of the boilers. Check flow through the
boilers including isolation valve and pump
operation.
ModSync® displays *** for
temperatures instead of a value.
The ModSync® sensor reading is out of range.
Check wiring and sensor operation.
