UNDERSTANDING THE CYCLE CONCEPT
The Heat-Timer MPC Platinum is a microprocessor-based control designed to manage a low-pressure steam heating system. It
operates a steam boiler or a two-way steam valve to provide the desired amount of heat to the building.
The MPC Platinum operates based on the CYCLE principle. Heat-Timer created this principal specically for steam heating
systems to overcome the inabilities of standard thermostatic controls to cope with the unique challenges of low-pressure steam
heating. Unlike water and air systems, steam systems take time to build up a "head of steam". Moreover, once the system starts
heating up, it has momentum that takes time to dissipate. This makes it difcult to control its temperature.

Cycle length based on outdoor temperature
By monitoring the outside temperature, the MPC Platinum is able to anticipate the building heating needs. Each CYCLE period
(usually 60 minutes long, but adjustable depending on the type of radiation units) consist of a Cycle-ON segment and a Cycle-OFF
segment. The length of the Cycle-ON segment will vary with the outside temperature. The colder it is outside, the longer the
Cycle-ON part.

The MPC Platinum constantly checks the outside temperature by means of a solid-state sensor located on the exterior of the
building. At the same time, it monitors the heating system of the building by means of a heating system sensor. This heating system
sensor is located where it will show that heat has reached the furthest location in the building (or the hardest to heat area). Based on
this combined data, the MPC Platinum sends instructions to the heating plant to control the heat level in the building.
In addition to adjusting the length of the Cycle-ON segment, the outdoor temperature acts as a system cutoff. When the outdoor
temperature rises above one of the adjustable cutoff temperatures (Two outdoor cutoffs are available. One is for the day and the
other is for the night), the MPC Platinum will not call for any heat. When the outdoor temperature drops below the cutoff, the
MPC Platinum will automatically begin controlling the heating cycle. Once the heating system is active, the heating system sensor
will register when heat has reached throughout the building. The combined effect of these two sensors is to provide an even,
comfortable level of heat throughout the building.

Sample Cold Weather Cycle
The MPC Platinum is able to maintain two different heat levels. The Day heat level is the higher level of heat. It provides
comfortable temperatures when the building tenants are active. The Night heat level provides lower heat and conserves energy when
the building is empty or when tenants are asleep. Both heat levels rely on the identical cycle concept, but the lower Night settings
provide less heat given the same outdoor temperature.
SEQUENCE OF OPERATION
• The MPC Platinum activates the steam source when the outside temperature falls below the outdoor sensor cutoff (factory set at
55°F for Day and 40°F for Night, but fully adjustable).
• The MPC Platinum will continue to call for heat, keeping the steam source active, until the heating system sensor reaches its
adjustable Set Point. This indicates that steam has gotten entirely through the system, or that "heat is established".
• Once "heat is established", the Cycle-ON segment of the cycle will begin.
• During the Cycle-ON period, the MPC Platinum will keep the steam source activated. The length of the ON part of the cycle
is dependent on the outdoor temperature, the Day/Night setting, and several user selectable adjustments that can be tuned to the
specic heat loss characteristics of the building.
• Once the Cycle-ON part has ended, the Cycle-OFF part of the cycle will begin. The MPC Platinum will turn off the boiler or
close the steam valve for the remainder of this cycle.
• When the Cycle-OFF part is over, the MPC Platinum will once again activate the steam source unless either the outside
temperature has risen above the cuttoff, or the thermal lockout is active.
• With the thermal lockout, the heating system sensor temperature must fall below the Set Point through an adjustable differential
before the heating source can be reactivated. This allows residual heat in the pipes to continue to heat the building. Once the
pipes have cooled sufciently, a new cycle can begin.
• However, if the MPC Platinum is an Internet capable control and space sensors are installed, the control checks for Space Lockout
before staring another cycle.

• During a heating cycle, the control switches between the different cycle states. The states are divided into groups.
• During any of the operational states, the control has the output relays energized. And during the energy saving states, the control
has the output relays de-energized.
• An Internet control Cycle Timeline is viewable on the History tab of the ICMS site. They are part of the Stock History.
• State Groups are divided into either Boiler-On or Boiler-Off. The Boiler-On groups are represented by the reddish background.
They are graphed on the upper portion of the Cycle-Timeline Internet history graph. The Boiler-Off groups are graphed on the
bottom portion of the graph and has a bluish background.
• These Internet graphs help troubleshoot and ne tune the control operation.
TYPICAL STEAM HEAT CONFIGURATION
The MPC Platinum works with virtually any non-vacuum steam heated system. The MPC Platinum can control a boiler directly to
create steam. For systems where a central plant provides steam, the MPC Platinum opens or closes a motorized valve to allow or
prevent steam from entering the heating system. The MPC Platinum also works with one or two-pipe steam systems.
However, based upon the specic layout of the steam heating system there are several differences in locating the heating system
sensor and in the output wiring to the boiler or motorized valve that the user need to observe. It is important to carefully check the
piping diagrams at the end of this manual to determine which of the following four layouts matches your heating system:
• One Pipe Steam - Motorized Valve
• Two Pipe Steam - Motorized Valve
• One Pipe Steam - Direct Burner Operation
• Two Pipe Steam - Direct Burner Operation
For subatmospheric vacuum type steam systems, see Heat-Timer SRC Platinum Control on the Heat-Timer web site
(http://www.heat-timer.com).
INITIAL PROGRAM
Setting an Initial Program ease's the conguration of the MPC Platinum while giving the opportunity to utilize many of the energy
saving and comfort features. The program should consist of the following:
• Select the features your system can utilize,
• Make sure you have the right control and accessories,
• Install the Control,
• Set the System Startup,
• Set the System Settings,
• Set the Schedules
• Adjust the Day and Night Heat Adjustments and the Set Point
SELECTING THE SYSTEM FEATURES
Heat-Timer designed the MPC Platinum with low-pressure steam building heating as the primary purpose. With this in mind, the
user can use many of the control features to ease, enhance, and improve the system performance. Below is a list of its major features.
Steam Outdoor Reset
• The MPC Platinum regulates the amount of steam sent to the building based on the outdoor temperature. It uses the Cycle concept
based on the Day and Night Heat Adjustment and outdoor cutoffs to regulate the heat. The colder it gets, the longer the Cycle-On
runs. See "AUTO/BYPASS Switch" on page 16.
Night Setback
• Whenever the outdoor temperature falls below the Outdoor Cutoff, the MPC Platinum adjusts the Cycle-ON and Cycle-OFF ratio
to hold a constant Day or Night heat level. The Night heat level is for when the building is unoccupied or tenants are sleeping.
Day and Night Schedules
• The MPC Platinum has 4 Day and 4 Night settings for each day of the week. By setting a Schedule, Day and Night Heat
Adjustments, and Outdoor Cutoffs, you can save energy while providing comfortable heat to the building. The settings allow
the MPC Platinum to reduce the length of the steam Cycle-ON portion during the night or when building is unoccupied. See
"Schedules" on page 29.
HT# 059085-00 F

MPC Platinum Installation and Operation Manual
Vacation Schedule (Available with Internet Control Only)
• This feature gives the user the ability to provide a lower-than-night space target between two specied date-time combinations.
This provides additional savings for schools and ofce buildings to use in long holiday periods. See "Vacation Schedule Setting"
on page 30.
Space Sensor Feedback (Available with Internet Control Only)
• For better control and much more energy saving capabilities you can add wireless or wired space sensors to the MPC Platinum to
ne tune its operation and increase the system's overall efciency. When you add space sensors to the space average, the MPC
Platinum checks the space average before the beginning of each cycle to determine if the building is sufciently heated. See
"Space Lockout" on page 28.
System Output
• The system output relay connects to and operates a combustion air-damper or other boiler room equipment and it will energize
whenever there is a call for the boiler. In addition, if you connect the combustion air-damper's end-switch to the Prove input
terminals, it will stop the boiler from ring if the damper is not fully open. See "Installation" on page 8.
Boost and Early Shutdown
• The boost returns the building to its Day (Normal) heat level after Night (Setback) heat level. It does it by running the burner
or valve output for a period of time that depends on the outside temperature. It offers an adjustable curve parameter to tune its
operation to the specic building. See "Boost Mode" on page 26.
• The Early Shutdown feature shifts the Day schedule to Night Setback before the last Night Time setting for that day. The Early
Shutdown varies based on Outdoor temperature (OD). The warmer the Outdoor temperature the earlier the MPC Platinum shifts to
Night Setback. See "Early Shutdown Curves" on page 27.
Remote Communication
• The MPC Platinum is upgradable to Internet, BACnet IP, BACnet MSTP, or MODBUS communication to allow monitoring and
controlling of all of its functions from a remote location. Only the Internet communication package allows the MPC Platinum to
accept a variety of additional sensor inputs to monitor their status and provide web, E-Mail, or text message alarms under specied
adjustable conditions.

• All non-communication MPC Platinum controls are upgradable to any of the available communication options. This, requires the
• The Upgrade Kit consist of two boards, a CPU Board and a Communication Board. The CPU Board has the control operating
software.
• All communication boards have an Ethernet socket that is used for the BACnet IP or Internet communication and a RS485 socket
that is used for BACnet MS/TP or MODBUS communication.
• Both boards are mounted on the back of the Platinum control's motherboard. Thus, to install both boards you need to remove the
control from the enclosure by removing 3 facing screws. Then, turn the control over to reveal its back.
• Each of the boards is mounted on a group of standoffs that must be replaced during the upgrade. See "Remote Communication
Wiring" on page 14.
• Connect the communication cable from the side Knockout.
• Reinstall the Panel in the enclosure using 3 screws.

OUTDOOR SENSOR INSTALLATION
Only use the Heat-Timer sensor included with the unit (HT# 904220-00).
• Locate the sensor in the shade on the north side of the building. The sensor
should never be in direct sunlight.
• Be sure the location is away from doors, windows, exhaust fans, vents, or other
possible heat or cool sources.
• The sensor should be mounted approximately 10’ feet above ground level.
• Adhere the Outdoor Label provided to the back of the sensor base.
• Use the Enclosure Base bottom knockout for the conduit. Use the locknut to hold
the conduit and enclosure base together. Screw the cover to the base.
• Make sure to seal around the sensor enclosure and wall except from the bottom.
• The sensor wires can be extended up to 500’ using shielded 2-conductor cable
(HT# 703001-01) (#18/2). Do not connect the shield at the sensor. However,
connect it at the control using the terminal marked with an “O”.
• Do not run sensor wires in conduit with line voltage wiring.
Determining the proper location for the Outdoor Sensor is very important. The MPC Platinum will
base the heat on the outdoor temperature information it receives from this location. If the sensor is in
the sun, or covered with ice, its reading will be different from the actual Outdoor temperature (OD).
HEATING SYSTEM SENSOR (HSS) INSTALLATION
• Install the sensor at one of the following locations:
The ideal location for the HSS is on the furthest radiator in the system. This
radiator is usually the hardest to heat.
The sensor may be located on the furthest return riser. However, the sensor
MUST be above the boiler water line (on a dry return).
• Only use the sensor provided with the control. If you are replacing an earlier
Gold model Heat-Timer, it is NOT necessary to upgrade the sensor.
• Strap the HSS to the pipe using the tie-wraps provided with the outdoor sensor.
Then wrap insulation around the sensor and pipe to achieve the highest accuracy.
• The sensor wires can be extended up to 500' using a shielded 2-conductor cable
(HT# 703001-01) (#18/2).
• Do not connect the shield at the sensor. However, connect it at the control using
the terminal marked with an “O”.
• Do not run sensor wires in conduit or trough with line voltage wiring.

If the HSS cannot sense the system is full of steam, the MPC Platinum
will not provide comfortable heat levels. Be sure the HSS is located on
a properly vented pipe that cannot easily be isolated from the system.
Using a Pressutrol instead of the HSS
• Heat-Timer MPC Platinum control requires the use of a HSS. However, if a
good location for the HSS is not possible, it is acceptable to install a Pressuretrol
Adaptor Kit (HT# 900043-00) that connects to the boiler operating pressuretrol.
In this case, the system may not be as efcient as when using the HSS and the
Thermal Lockout feature will not be available..

• The MPC Platinum is equipped with a System output to operate additional equipment.
The most common use for this output is operating a combustion air-damper.
• The SYSTEM output terminals are 9 and 10. These terminals do not source any power.
Wire these terminals directly to the combustion air-damper activation terminals.
• The contacts can switch a 6A resistive at 120VAC load.
• A good practice is to use the MPC Platinum's Prove input terminals to connect to the
combustion air-damper End Switch. This prevents the MPC Platinum from activating
the boiler before fully opening the damper. See "Wiring The Prove" on page 12.
• The System relay energizes whenever the Output relay energizes. When the Output relay
de-energizes, the System relay remains energized for the System Run-On period before
de-energizing.
WIRING TO AUXILIARY CLOCK
• The MPC Platinum is equipped with an AUX CLOCK output (terminals 11 and 12). Use
the output to operate additional equipment based on the Aux Schedule. A common use is
to turn on and off a set of lights based on a schedule. See "Aux Relay Schedule" on page
30.
• The AUX CLOCK output terminals do not source any power. Wire the AUX CLOCK
terminals directly to the equipment activation terminals if the equipment does not require
any power.
• If the equipment controlled require powering, make sure that its power consumption does
not exceed the output relay rating. Otherwise, use an isolation relay.

outputs to operate additional equipment based on the control logic. Each of the Option
output relays has different logic operating choices. Select the desired choice from the
Startup Menu. See "Option Outputs Modes" on page 21.
• If the control is an Internet capable control, the OPTION3 output relay will function as a
relay to manage a cable or DSL modem's power.
• The OPTION output terminals do not source any power. Wire the OPTION terminals
directly to the equipment activation terminals if the equipment does not require any
power.
• If the equipment controlled require powering, make sure that its power consumption does
not exceed the output relay rating. Otherwise, use an isolation relay. In this case, use the
OPTION terminal to break the hot power wire. going to the equipment. Then, connect
the neutral wire directly the equipment second terminal.
On Internet capable controls, you MUST use Option 3 output to
manage the power to Cable and DSL modems. However, DO NOT
use Option 3 Output to manage the power to Cellular Modems.

WIRING THE SHUTDOWN
• You can use this feature whenever it is desirable to deactivate the MPC Platinum from a
remote location or another controller like a Building Management System (BMS).
• The Shutdown feature de-energizes the BURNER and MOTORIZED VALVE output
relays, turning off the boiler or closing the motorized valve. However, the SYSTEM relay
will remain energized for the period of the System Run-On. See "System Run-On" on
page 28.
• The Shutdown signal must be a dry contact only. DO NOT place voltage across the
SHUTDOWN terminals.
• Bring the two wires from the dry contact to the terminals marked SHUTDOWN- A3, A4.
WIRING THE PROVE
• The MPC Platinum uses the Prove input to check system operation before activating the
outputs. A good practice is to use the MPC Platinum's Prove input terminals to connect
to the combustion air-damper End Switch. This prevents the MPC Platinum from
activating the boiler before fully opening the damper. See "Installation" on page 8.
• If the PROVE input terminals are open, the MPC Platinum will enable only the System
relay. The Burner and Motorized valve (OUTPUT) relays will be de-energized when the
PROVE input is open.

DHW ENERGY SAVER WIRING
• The DHW Energy Saver communicates all of its information to the Platinum control
using RS485 (3-wire connection).
• The DHW Energy Saver RS485 terminals are wired to the Platinum main board’s
RS485 (under the PCB board).
• Follow the wiring as per the graph on the right.
ALERT
DO NOT connect the DHW Energy Saver to the RS485 on the Platinum RI board.
Instead, connect the DHW Energy Saver RS485 to the Platinum main board.
• Maximum wiring length should not exceed 100 Feet. Use 18 gauge 2-conductor
shielded wire (#18). Connect the shield to the middle terminals on both of the RS485
connections. To eliminate communication errors, DO NOT splice the communication
cable wires.
• When connecting the DHW Energy Saver and a Platinum Extension to the same
connector, make sure to splice the cables externally before bringing them to the RS485
Plug Connector on the main Platinum Board. See "DHW Energy Saver Manual".

• The switch must be in the AUTO position for the MPC Platinum to control the heating
system.
• The BYPASS position overrides all automatic control of the MPC Platinum.
• If the MPC Platinum has power and is operational, switching to BYPASS automatically
activates the Motorized Valve, the Burner, and the System output.
• Switching the control to BYPASS manually during a power outage, activates the
Motorized Valve, Burner , and System outputs.
ALERT
Switching the MPC Platinum into Bypass overrides all automatic operation. In
Bypass, the boiler will run constantly on its own limits or the valve will be fully open.

MENU TYPES
When powering up the MPC Platinum for the rst time, it will take you through an 70
second count down followed by the System Startup Settings then another 10 second boot
setup and nally end with the default screen. Once the control is mounted and wired, set
up an initial pilot program.
• Set and adjust System Startup Settings: The contractor sets these values after installing
the control for the rst time. End users should avoid changing these settings as they
will change the control operating logic. If the Startup Settings are not correct, the MPC
Platinum may operate the system incorrectly.
• Set and adjust System Settings: These settings adjust the system to the specic building
characteristics. These are general settings that control the amount of heat provided. The
default settings will generally work in most applications, but adjustments should ne-
tune the performance of your system.
• Set and adjust Maintenance: Provide calibration tools for the sensors and allow a
password to be set.
• Set and adjust Schedules: Sets the Day/Night heat schedule and the Aux clock schedule.
Four pairs of Day/Night times can be set for each day of the week. In addition, the Aux
relay is capable of following the Aux Schedule. It is programmable to turn on or off up
to eight times per day.
• Shift: Allows you to temporarily shift from Day (higher heat level) to Night (lower
heat level) settings, or vice versa, without reprogramming the times of the Day/Night
Schedule.
Depress the knob to move
forward through the menus and to
accept changes. To change a
setting's value, rotate the knob.
