1.4.3.4 Safety and Ignition Module (SIM) Menu
The SIM reports sensor readings and information on the status bar. In the controller's SIM
menu, you can:
View Status - Provides an overview of the burner, gas valve, ignitor and venting.
Perform a Hi-Limit Test - Test the maximum supply cutoff temperature on the boiler. If
the SIM detects a high limit temperature, the boiler enters a lockout state. For
instructions, see Testing the Hi-limit temperature function on page 62.
Perform a Module Reset - Lockouts are typically 5 minutes, depending on the ignition
error. Use the Module Reset function to clear a lockout quickly. For instructions, see
Resetting a boiler after a SIM module ignition lockout on page 85.
Perform a LWCO Test - Test the low water cutoff to protect against low water in a boiler.
If the SIM detects low water, the boiler enters a lockout state. For instructions, see
Testing the low water cutoff (LWCO) function on page 62.
