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
HT# 059299-00 A
The Internet communication option gives remote access to the control from
any computer with a web browser The access is through Heat-Timer ICMS
web site Internet ready controls have the capability to connect to a large
number of network sensors These sensors can be space, temperature,
pressure, oil tank levels, and many more Furthermore, the Internet option
adds history graphing, export reports to e-mail, and alarming that is delivered
by e-mail, web, and text messaging See "Internet Communication" on page
45
The Multi-MOD Platinum can be upgraded to communicate over BACnet IP
or MSTP networks All Multi-MOD Platinum functions can be monitored from
a remote location See BACnet Communication Upgrade Manual
The Multi-MOD Platinum can be upgraded to communicate over Modbus
RTU networks All Multi-MOD Platinum functions can be monitored from a
remote location See Modbus Communication Upgrade Manual
When the Multi-MOD Platinum is equipped with Internet communication,
it can connect to a large number of wireless and wired space sensors It
uses the space average temperature to regulate the building heat for better
comfort control and fuel savings See "Space Feedback Concept" on page 6
The Multi-MOD Platinum modulates the boilers to achieve the smoothest operation and highest system
efciency It does that by overlapping the lead and lag boiler operation The concept depends on the
Ignition % and the Modulation Start %

When the control needs to start heating, it activates the System output In most cases, this output operates
a system pump or a combustion air damper Then, the control checks the safety components operation
status by checking the Prove input for closure If the Prove signal was shorted, the control starts the
lead boiler Purge Whenever a boiler is activated, it must rst go through the Purge period See "Purge
Delay" on page 36 During Purge the control sets the boiler modulation to the lowest ring rate set by the
Ignition % See "Ignition %" on page 40 After the Purge ends, the control starts to modulate the lead boiler
gradually Whenever, the lead boiler reaches its Modulation Start %, the control starts the lag boiler Purge
See "Modulation Start" on page 40 After the lead boiler reaches its full capacity, the lag boiler may start its
upward modulation This process repeats for each additional lag boiler or until the system is satised

When the load is reduced, the control will gradually decrease the lag boiler's modulation until it reaches its
lowest ring % The lag boiler will remain at the Ignition % while the control is reducing the lead boiler's
modulation When the lead boiler reaches 40% of the Modulation Start %, the control turns off the lag
boiler
The Multi-MOD Platinum has multiple operating modes that
satisfy most hydronic or steam systems When used to control
a hydronic system, it can change the target Set Point based
on outdoor temperature (Outdoor Reset) or it can modulate its
stages to achieve a xed Set Point
In Outdoor Reset, the Multi-MOD Platinum controls a hot water
heating system to provide a building with comfortable and even
heat levels It varies the temperature of the circulating heating
water in response to changes in the outdoor temperature The
heating water temperature is controlled through the modulation of
the stages
The Multi-MOD Platinum also controls the system-circulating
pump with an adjustable Outdoor Cutoff When the outdoor
temperature is above Outdoor Cutoff, the pump is off and no
heating water is circulated through the system When the outdoor
temperature drops below the Outdoor Cutoff, the system pump
output is activated and the heating water circulates through the
system The temperature of the heating water is controlled by the
Reset Ratio, Offset, Minimum Target, Maximum Target, and the
outdoor temperature

When a building is being heated, heat escapes through the walls,
doors, and windows to the colder outside air The colder the
outside temperature, the more heat escapes If you can input
heat into the building at the same rate that it is lost out of the
building, then the building temperature will remain constant The
Reset Ratio is an adjustment that lets the building achieve this
equilibrium between heat input and heat loss Outdoor reset is
the most efcient way a building can be heated
HT# 059299-00 A
The starting reset ratio for most systems is the 100 (OD):100
(SYS) (Outdoor Temperature : Heating Water Temperature) ratio
This means that for every degree the outdoor temperature drops,
the temperature of the heating water will increase one degree
The starting point of the ratio is adjustable, but comes factory
set to 70°F Outdoor Temperature and 100°F Water Temperature
For example with a 100 (OD):100 (SYS) ratio, if the outdoor
temperature is 50°F, this means that the outdoor temperature has
fallen 20° from the starting point of 70°F Therefore, the heating
water temperature will increase 20° to 120°F (100°F + 20°F)
When controlling a none-condensing
boiler directly without the use of a
mixing valve, minimum boiler water
temperature must be set to boiler
manufacturer specifications In that
case, system temperature must not go
below such temperature
Each building has different heat loss characteristics A very well
insulated building will not lose much heat to the outside air, and
may need a Reset Ratio of 200 (OD):100 (SYS) (Outdoor :
Water) This means that the outdoor temperature would have
to drop 2° to increase the water temperature 1 degree On the
other hand, a poorly insulated building with insufcient radiation
may need a Reset Ratio of 100 (OD):200 (SYS) This means
that for each degree the outdoor temperature drops the water
temperature will increase 2° The Multi-MOD Platinum has
a full range of Reset Ratios to match any buildings heat loss
characteristics
A heating curve that relies not only on Outdoor temperature but
also on type of radiation will improve the comfort See the Building
Suggested Settings table for different types of radiation based on
an average building insulation and heat loss The contractor can
ne-tune these settings to the specic building need
Radiators (Steel & Cast
Iron) 100 : 100 0˚F
Baseboard (Finned copper
tube& Cast Iron) 100 : 100 0˚F
Radiant (High Mass/
Concrete) 400 : 100 -10˚F
Radiant (Low Mass/Joists) 200 : 100 -10˚F
Fan Coils & Air Handlers 100 : 100 20˚F
A Multi-MOD Platinum control that is equipped with Internet
communication is capable of using Heat-Timer space sensors to
ne-tune its outdoor reset operation while providing signicant
savings The Multi-MOD Platinum adjusts the target water
temperature based on the Space Feedback Gain and the
difference between the current Space Average and the Space
target Example: Using a Space Feedback Gain of 4, if the
Space Average is 70°F and the day target is set to 72°F, the
control will add 4° to the System Target temperature for every 1°
(ambient temperature) the Space Average is below the Space
Target In this example, it would add 8° to the target water
temperature to compensate for the 2° reduction in the Space
Average See "Space Feedback Gain" on page 47
If the Space temperature exceeded the Space Target by 2°
while the target water temperature is at the Minimum Target
temperature for an hour, the control will turn the boilers off until
the Space Average drops below the Space Target
HT# 059299-00 A
Setting an Initial Pilot Program eases the installation and conguration of the Multi-MOD Platinum and gives
the opportunity to use many of the energy saving features while providing comfort
The program should consist of the following:
• Select the features that your system can utilize,
• Making sure you are ordering the right control and accessories (Multi-MOD Platinums do not come with
sensors or stage relays, these items must be ordered separately,
• Install and wire the Control,
• Set the System Startup menu,
• Set the System Settings,
• Set the Stages and their rotation,
• Set the Schedules
• Adjust the Reset Ratio and Water Offset (In Reset Mode Only) or set the Set Point,
The following are for communication equipped controls only:
• If the control had communication, connect and install the communication,
• If the control had Internet communication, install and wire the sensors
If you need the Multi-MOD Platinum to do additional tasks that either is not listed or do not know
how to congure them, contact Heat-Timer Corp Sales Department either by Phone (973)575-4004,

• 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
• 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

• To have the Multi-MOD Platinum operate the boilers and their pumps, use
SPDT relays (Single-Pole Double-Throw) and TDR relays (Time-Delay
relay)
• The SPDT relay sends the activation signal from the Multi-MOD Platinum
stage activation output to the boiler Interlock (TT) and its pump
• The TDR relay receives the SPDT pump activation signal and send it to the
pump When the SPDT relay signal ends, the TDR keeps the pump running
for an additional period This additional delay acts as the Run-On delay
available for the System output See "System Run-On" on page 34

• 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

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

is required during the night or on the weekends when a building is
unoccupied, but a minimum level of heat is still required
• To use the Setback, the EMS Input mode must be set to Setback
See "EMS Input Mode" on page 27 Also, the Setback value must
be greater than 0 See "Setback" on page 35
• The Setback can be activated based on the Night Schedule
settings or an external dry-contact Setback input
• When using an external Setback, wire the dry-contact Setback
signal to the EMS terminals (+) and (SIGNAL)
• When the Setback terminals are shorted, the Setback is enabled
and the Multi-MOD Platinum will hold the lower Set Point The
main display will show "Setback to: 150F" to indicate this
condition
• When the setback signal ends, the Multi-MOD Platinum will revert
