Multi-MOD Platinum with Space and Scheduling Installation and Operation Manual

HT# 059299-00

MODulATION SPeeD

(Available in Process Mode Only)

Adjustable from 0.1 to 6.0 minutes 

Default: 0.1 minutes

PReSS TO SeleCT:

 /<Maintenance>/Mod Speed

•   Modulation Speed is designed to match the burner modulating speed to 

the Multi-MOD's logic .  This helps the Multi-MOD Platinum to respond 

accurately to system changes .  See "Operating Mode" on page 28 . .

Adjust the Modulation Speed 

to the motor with the slowest 

modulation .

•   The Lead Stage is the first stage brought on when output is required .
•   Rotating the lead stage evens the wear on each stage and prolongs the 

life of the units .

•   Only stages their Mode is set to Auto can be Lead .  Therefore, not all 

stages may be available when manually selecting a new lead stage .

•   The current Lead Stage is shown in brackets on the display .

stages and prolongs their lives .

Time

•   Timed rotation starts the lead stage followed by the lag stage .  When 

turning stages off, it turns off the lag stages before the lead stage .  

Example: If stages "<A>", "B", and "C" are on while "<A>" is the lead, 

then when turning off the stages it will turn off stage "C" followed by "B" 

and then finally "<A>" .

•   If 24 Hours (default setting) was selected, the first rotation will take effect 

after 12 hours .  The following rotations will take place every 24 hours 

thereafter .  However, if Time rotation was set to other than 24 hours, the 

rotation timer will start from the moment the setting is changed .

last on

•   Unlike Time rotation, Last-On turns off the last stage turned on last .  

Example: If "<A>" is the lead, the starting sequence of the boilers will be 

"A", "B", then "C" .  When the turning off the stages, it will turn off "A", "B", 

followed by  "C" .  Then, "<D>" will be the new lead stage .
