• The System Prove feature is provided to check the system
component operation status before activating any stages Prove
must be selected from the Prove/DHW Startup option See
"Prove/DHW Mode" on page 28
• A typical use of this feature is to check for water ow before ring
any boiler stages When there is a call for heat, the System
Output relay activates the system pump When the pump
establishes ow, a ow switch closes the Prove input terminals
Only then, can the Multi-MOD Platinum activate and modulate the
boilers as required to hold the set point
• If the Prove input is open on a call for a stage, the Multi-MOD
Platinum will enable only the System output All stage outputs
will be off when the Prove input is open
• A factory installed jumper provides the System Prove signal Do
not remove the jumper unless it is replaced by a Prove signal

Do not remove the factory installed
Prove jumper unless it is replaced
by a prove signal If the Prove input
is not closed/shorted, the Multi-MOD
Platinum will NOT activate the stages
The Prove input cannot be used as
a safety limit All equipment must
have its own certified limit and safety
controls as required by code
• The DHW Call feature is used to raise the system Target to the
DHW Set Point In addition, it regulates the operation of the
System output The System output operation varies based on
the DHW Priority setting selected from the Startup menu See
"Prove/DHW Mode" on page 28
• Wire a DHW aquastat to the DHW Call terminals The call must
be dry-contact
• Remove the jumper on the DHW terminals for proper operation

• The Multi-MOD Platinum will not activate or modulate any Stage
in Lockout A Lockout signal tells the Multi-MOD Platinum that
the related stage is encountering a problem and cannot be
started The Stage display status will show (L/O)
• However, using the Lockout will drastically improve the control's
set point management
• There is a Lockout input for each stage on the Multi-MOD
Platinum and Extension Module
• The Lockout signal must be a dry-contact closure from the boiler
No voltage can be placed across the terminals If the source of
the signal has voltage, use a relay
