MulTI-MOD PlATINuM OVeRVIeW

The Multi-MOD Platinum is a multi-boiler modulating control . It uses PID logic in addition to overlapping
the lead and lag boiler modulation, its patent logic, to achieve a smooth modulation and efficient system
performance . It is capable of modulating 4 on board boilers . When used with extensions panels it can
connect to a total of 20 modulating boilers . Up to two external extensions can be used, each connecting to
8 modulating boilers . The Multi-MOD Platinum is used in a variety of applications including building heating
and process applications .

Multi-MOD Platinum with Space and Scheduling Installation and Operation Manual
The Multi-MOD Platinum can operate in heating or cooling applications .
When connected to a temperature sensor and an outdoor sensor, the Multi-MOD Platinum
can change the target based on the outdoor temperature (Outdoor Reset) or it can
modulate the boilers to maintain a fixed set point . See "Sensor Type" on page 26 .
The Multi-MOD Platinum can operate in a temperature or pressure environment to
maintain a set point . For high temperature applications it can connect to 4-20mA
temperature sensors . See "Sensor Type" on page 26 .
It accurately modulate motors using any of the 0-5V, 0-10V, 1-5V, 2-10V, 4-20 mA, or
0-135Ω modulating signals . It can also modulate a combination of boilers with different
modulating signals . See "Output Type" on page 27 .
The Multi-MOD Platinum now has a built-in 7-day schedule . Each day has 4 day and 4
night time settings . See "Schedules" on page 42 .
The Multi-MOD Platinum can accept setback input from external controls to lower the
target Set Point . See "Setback Wiring" on page 20 and "Setback" on page 35 .
The Boost raises the building space temperature to day levels quicker . It does that by
raising the target water temperature before the first day schedule . See "Boost and Early
Shutdown" on page 34 .
This feature allows the user to temporarily switch the control from Night Time settings to
Day Time settings or visa versa . See "Shift" on page 42 .
The outdoor sensor is used to turn all the outputs off whenever the outdoor temperature
rises above the outdoor Cutoff value . See "Outdoor Cutoff Temperature" on page 32 .
The Multi-MOD Platinum operation can be turned off during off-season using the Season
setting . See "Season" on page 32 .
The control has three modes of rotation: Manual, Last-On, or Automatic . The Automatic
option rotates the stages based on time . See "Lead Stage Rotation" on page 38 .
in fast responding systems . See "Modulating Mode" on page 28 .
Any stage can be set to be a standby boiler (backup boiler) . A Standby boiler will only run
after the rest of the boilers reach full fire and remain at it for the Standby Delay period .
See "Standby Time" on page 37 .
This input checks for component status before activating any stage . It can be used to
check the combustion air damper or flow switch status . See "Prove Wiring" on page 19 .
This input turns off the heating from a remote location . See "Shutdown Wiring" on page 18 .
This output can be used to activate a system pump, combustion air damper, or perform
any other function that is required before any stage is activated .
The control offers multiple DHW Priority options . See "Prove/DHW Mode" on page 28 .
The Multi-MOD Platinum can accept a remote 4-20 mA set point signal . See "External
Set Point Wiring" on page 22 .
The Gain adjusts the aggressiveness of the modulation . See "Gain" on page 36 . .
This feature is used primarily to reduce boiler short cycling . The Last Stage Hold
maintains the system on longer and off longer . See "Last-Stage-Hold" on page 37 .
The Multi-MOD Platinum is equipped with a password that is used to stop unauthorized
user from changing any of the control settings . See "Security" on page 48 .
