• The System output can be used to activate a pump, a pump starter, a
combustion air damper, or other equipment .
• The Multi-MOD Platinum activates the System output whenever there is a
call for any of the stages . The System output remains energized whenever
a stage is active .
• The System output does not source any power . A separate power source
is required for the equipment .
• The System relay comes pre-installed .
System Output Operation in Set Point Mode
• If an outdoor sensor was used, the System output will remain active after
all the stages are turned off for as long as the outdoor temperature is below
the outdoor Cutoff . See "Outdoor Cutoff Temperature" on page 32 . If the
outdoor temperature rises 2° above the outdoor Cutoff, the System output
de-activates after it runs for the full Run-On period . See "System Run-On"
on page 34 .
• If no outdoor sensor was used and after the last stage turns off, the System
output runs for the Run-On period before turning off .
System Output Operation in Reset Mode
• The System output activated whenever the outdoor temperature drops
below the outdoor Cutoff .
• When the outdoor temperature rises 2°F above the Outdoor Cutoff, the
System output will remain active for the Run-On, then turn off .

• The Multi-MOD Platinum is designed to operate up to four boilers without
the addition of Extensions modules . The Multi-MOD Platinum can connect
to a maximum of two Extension modules maximizing the number of stages
controlled to 20 . Each Extension module can connect to a maximum of
eight stages .
• Each of the Multi-MOD Platinum or extension stages has an activation
output in addition to the modulation output . Each of the stage outputs has
an LED to show its status .
• Some modulating boilers may require an activation signal . The stage
activation output is used to provide this signal . To use the stage activation
output, you must install a relay in the stage relay socket . Relays must be
ordered separately (HT# 500054-00) .
• Each output relay on the Multi-MOD is rated for 1 Amp at 120 VAC 60 Hz .
• Wire the stage activation signal in series with the boiler limits .

For proper operation set the Mode of any
unused stage to Off . See "Mode" on page 39 .
