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 efcient 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
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 xed 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 rst 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
Use Normal (PID) logic for slow responding systems as in heating systems Use Process
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 re 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 ow 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
