Process Menu
Process Set Point
A maximum of (8) Process Set Points are available with a temperature
range of 60°F (15°C) to 240°F (115°C).
The Process Set Point is displayed as “SP.”
Process Set Points not being used can be turned to an “Off” setting.
Process Times (TM02 required)
Any of the (8) Processes can be timed. Each timed Process has a range of
00:00:01 to 23:59:59. The conclusion of a timed Process will immediately
proceed into the next Process. If the last Process of the program is timed, it
will proceed to the selected start position (see Looping Mode, page 7) after
timing out. The letter “T” will be displayed indicating a timed Process. Press
the up or down arrows on the TDM02 to scroll between the screens show-
ing the Process Set Point and the sensed temperature AND the sensed
temperature with the time remaining in the Process (hh:mm:ss).
Operation Menu
Soft Start (Global Setting)
The Soft Start feature controls the initial rate of voltage change to the mod-
ulator. Soft Start operates when switching from a lower Process tempera-
ture to a higher Process temperature. It is designed to slow the initial input
rate to the burner. This feature is available in three settings: slow, medium,
and fast and may be turned off. “Ss” (slow), “Sm” (medium) or “Sf” (fast)
is displayed during the time the Soft Start is active. This feature is compre-
hensive to all Set Points.
Max Valve VDC (Global Setting)
This feature limits the maximum voltage applied to the modulator. It has a set-
ting range of 7 to 25 VDC. This feature is comprehensive to all Set Points.

Offset Temp
This feature is used to maintain a desired temperature in an area not
being directly sensed by the MP2+ system. The average difference be-
tween the MP2+ sensed discharged temperature and the desired space
temperature must be known. This is the Offset. The Offset will set the
MP2+ sensed discharged air needed to produce the desired space tem-
perature. Decrease (-) the Offset to maintain and control space tempera-
ture lower than MP2+ discharged temperature. Increase (+) the Offset to
maintain and control space temperature higher than MP2+ discharged
temperature. The space temperature will be displayed as the Process
Set Point.
The feature has a range of -10°F (-5.6°C) to +10°F (5.6°C) and is avail-
able for each Process.
Ramping
This feature is used to step the input rate when changing from one Pro-
cess Set Point to another. It is available for each Process. The Ramping
Rate determines the amount of temperature change per hour in one-min-
ute steps. It has a range of 60 Deg/hr to 900 Deg/hr. The change can be
positive or negative.
Example
1 Program Offset to -5°F.
2 Program Process Set Point (desired space temperature) to 75°F.
3 Therefore discharge air temperature = 80°F.
(Required MP2+ discharge air temperature to maintain desired space temperature.)
4 The MP2+ discharged air temp. is 80°F. The displayed Process Set Point is 75°F.
Features

Max Ramp VDC
This feature limits the maximum voltage applied to the modulator while
operating in the Ramping mode. It has a setting range of 5 to 24 VDC. This
setting cannot exceed the maximum voltage output setting. This feature is
comprehensive to all Set Points.
Total Bandwidth (Global Setting)
This feature determines the amount of temp. change required to drive the
modulator from the minimum fire setting to the maximum fire setting and
vice versa. This feature is used to eliminate pulsating or hunting due to an
oversensitive application. Increase the Bandwidth if a pulsating or hunting
condition exists for an extended period of time after a Set Point change.
The feature has a range of 5°F (2.8°C) to 15°F (8.3°C). Total Bandwidth is
comprehensive to all Set Points.

This feature can be used with Max Ramp VDC and Soft Start to smooth the
stepping. (Soft Start only works when Process Temperature increases.)
“Ramp” is displayed to indicate the Ramping feature is active.
Timers
The controller features two Timers (Timer 1 and Timer 2) that accumulate
the hours of operation for each Process. Each Process has a Timer 1 and
a Timer 2. The TM02 is required.
Timer 1
Timer 1 logs the hours of operation for a Process. It will log up 999 hours
at which time it will automatically reset to zero. The hours can be user
reset to zero at any time. It also has a programmable alarm setting to no-
tify the user (by flashing a character in the lower right hand corner of the
display) when the desired accumulated hours for the Process have been
reached. It has a setting range of 1 to 999 hours. The feature is useful in
maintaining maintenance requirements.
Timer 2
Timer 2 logs the hours of operation for a Process. It will log up 999 hours
at which time it will automatically reset to zero. The hours can be user re-
set to zero at any time. The feature is useful in maintaining maintenance
requirements.
Diagnostic Menu
Max Proc Temp (Global Setting)
This feature limits the maximum temperature for each Process. It has a
range of 60°F (15°C) to 240°F (115°C). It does not allow the Process Set
Point to be set in excess of the Maximum Process Temperature setting.

Example
Process 1 = 75°F
Process 2 = 125°F
Process 2 Ramp Rate = 600 Deg/hr or 10 Deg/min
1 The control switches from Process 1 to Process 2.
2 The controller will immediately raise the temperature 10° and will hold it at the
new set point 85°F (75°F + 10°F) until 1 minute has passed.
3 It will continue to raise it 10° each subsequent minute until it meets Process 2.
4 It will take 5 steps (10°F each) and 4+ minutes to go from 75°F to 125°F.

Monitor (Global Setting)
The Monitor feature is a useful tool when setting up or troubleshooting
the MP2+ system. The following will appear on the display when Monitor
is in the “On” position:

Min Proc Temp (Global Setting)
This feature limits the minimum temperature for all Processes. It has a
range of 60°F (15°C) to 240°F (115°C). It does not allow any Process Set
Point to be set below the Minimum Process Temperature setting.
Calibration
This feature is used to fine-tune a particular application. Calibration shifts
the Bandwidth range up or down from the factory set mean. Each applica-
tion is different with variances in burners and appliances. It can be neces-
sary to change the midpoint of the modulation range to have the Process
Temperature and the actual sensed temperature match.
For sensed temperatures consistently displaying lower than the Set Point,
increase (+) Calibration by number of degrees off. For sensed tempera-
tures consistently displaying higher than the Set Point, decrease (-) Cali-
bration by number of degrees off. It is available for each Process and has
a range of –10°F (-5.6°C) to +10°F (5.6°C).
Looping Mode (Global Setting) - TM02 applications only
The looping mode feature is used to select the controllers default posi-
tion on startup and after the last process of a program is completed.
NOTE: On “Power up” the controller defaults to the last program
in use prior to removal of power. After last manual process of a
program or after last timed process of a program expires, the
controller defaults to the first process of the same program.

F/C Mode (Global Setting)
This feature sets the control to operate in either the Fahrenheit (F) or
Celsius (C) mode.
NOTE: Changing between Fahrenheit and Celsius will reset the control to
factory default settings.
Software Version (Global Setting)
Displays the version of software utilized by the controller.

Switching to another Program
Switching to another program can only be accomplished by entering the
Initial Programming Menu and selecting “Program Set #”.
Switching to Next Programmed Process
Push and release Button 1 on dial face (see page 11) or momentarily
latch (make) a set of contacts wired to the TB1 terminal (i.e. typically ac-
complished by a momentary ON (normally open) switch) to proceed to the
next Process. Pushing and releasing Button 1 or momentary latching of
TB1 during the last Process of a program will cause the MP2+ System to
return to Process 1. Multiple contacts used to switch Processes are to be

Switching to another Program
Switching to another program can only be accomplished by entering the
Initial Programming Menu and selecting “Program Set #”.
Switching to Next Programmed Process
Timed processes
Nothing is required. The MP2+ System will immediately proceed to the
next programmed Process after timing out.
NOTE: If the last Process of a program is timed, it will proceed either to the
“READY” position or to the First Process. By selecting the First Process in
the LOOPING Mode menu, the MP2+ can be programmed into a continuous
program loop (see page 7, LOOPING Mode).
Untimed (Manual) Processes
An untimed Process will remain in the Process indefinitely until Button 1 is
pushed and released or TB1 is momentarily latched. Pushing and releas-
ing Button 1 or the momentary latching of the TB1 will cause the MP2+
System to proceed to the next Process. If the last Process of a program
is untimed, pushing and releasing Button 1 or the momentary latching
of TB1 will cause the MP2+ system to proceed to the selected program
start position. Multiple contacts used to switch untimed Processes are to
be wired in parallel.
Aborting a Timed Process
Push and release Button 1 or momentarily latch TB1 twice within a 10 sec-
ond period or latch and hold continuously for 10 seconds.
Connecting Indicator Relays
Process 1 thru 8 indicators use a corresponding pair of terminals, labeled
Relay (1 - 8), on the TM02. The Program indicator uses a corresponding
terminal labeled Relay 9. Wire each indicator (LED, relay coil, etc.) 24
VDC 2 W maximum directly to the desired corresponding terminal. See
