WARNING
Electric shock hazard.
Can cause personal injury or equipment damage.
This equipment must be properly grounded. Connections and service to the MicroTech control
panel must be performed only by personnel that are knowledgeable in the operation of the
equipment being controlled.
NOTICE
This equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with this instruction manual, may cause interference to radio
communications. It has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his or her own
expense. McQuay International disclaims any liability resulting from any interference or
for the correction thereof.

Software ID
MicroTech RMC controller software is factory installed and tested in each panel prior to shipment.
The software is identified by a program code (also referred to as the “Ident”), which is printed on a
small label affixed to the MCB. The program code is also encoded in the controller’s memory and is
available for display on menu 16 of the keypad/display or a PC equipped with MicroTech Monitor™
software. (Information on using the keypad/display is included in the “Getting Started” portion of
this manual.) Using menu 16 or Monitor software is the most reliable way of determining the
controller’s program code.
RMC controller program codification is as follows:
RMC Panel
English units
Version (numeric)
Version revision (zero then alphabetical)
RMC-E01A
If the RMC Panel’s program code does not match the format shown above, it is likely that a special
program has been loaded into the controller. In this case, some of the information in this manual
may not be applicable.
Software Compatibility
At the time of this writing, the program code for RMC Panel software is RMC-E01A. In its default
configuration, this software is not compatible with some earlier versions of MicroTech applied
rooftop and SCAC controller software. The current software compatibility for the default
configuration is summarized in Table 3. The wildcard character ([) can be zero or any letter.
If you want to use an RMC Panel with older units that have incompatible software, the unit
controller software must be upgraded. However, there is one exception: If the units are older applied
rooftop units that have incompatible software and they do not need the RMC Panel’s common duct
static pressure control feature, you can either (1) upgrade the unit controller software or (2) set the
RMC controller’s Configuration parameter to “ALL RTU.” Note that when the Configuration
parameter is set to “ALL RTU,” the RMC controller’s software will become compatible with all
applied rooftop software and incompatible with all SCAC software. See the “RMC and Unit
Controller Setup” section of this manual for information on how to change the software
configuration.
If you have a version of applied rooftop or SCAC software that is later than the compatible
programs shown in Table 3, it is likely that program RMC-E01A is compatible with it; however, it
may not be. To find out for sure, contact McQuayService.

Getting Started
The MicroTech Remote Monitoring and Control (RMC) Panel is a self-contained device that is
capable of monitoring and controlling up to eight McQuay applied rooftop or self-contained air
conditioning (SCAC) units via network communications. You can display and modify information
in the RMC Panel and its associated unit controllers with either of the following methods:
• Using the keypad/display at the RMC Panel
• Using an optional PC equipped with Monitor software
You can also use the keypad/display at each unit, but then your access will be limited to that unit
only.
The following “Getting Started” sections describe how to use the RMC Panel’s keypad/display. (A
unit controller’s keypad/display operates similarly; the main difference is that the special keystroke
combination that changes the keypad-controller interface is not available.) For information on using
the optional Monitor software package, see the user’s manual supplied with the Monitor software.
The last “Getting Started” section describes how to set up the RMC Panel and its associated units
for normal operation.
Note: As used throughout this manual, the term “RMC network” denotes the RMC Panel and its
associated units; it would not include, for example, a reciprocating chiller that is on the same
MicroTech network. Therefore, an “RMC net work” could be either a self-contained network
(typical) or a part of a larger MicroTech network.
Using the Keypad/Display
The Keypad/Display Board, shown in Figure 1, is provided with the RMC Panel and all MicroTech
applied rooftop and SCAC unit controllers. With the keypad/display you can monitor operating
conditions, system alarms, control parameters, and schedules. After the password has been entered,
you can edit set points, parameters, and schedules.
The keypad/display on the RMC Panel can emulate each unit’s keypad/display. Once the RMC
Panel’s keypad/display is interfaced to the desired unit controller, it operates almost exactly the
same as the unit-mounted keypad/display. The only difference is that a unit’s service mode cannot
be changed from the RMC Panel. (A special keystroke combination changes the keypad-controller
interface). The Unit Selection LEDs on the panel face indicate which controller the keypad/display
is currently interfaced with.
Note: The fact that the service mode cannot be changed is not always true. This is not true for older
versions of applied rooftop programs.

Menu Structure
The keypad accessible information in the MicroTech controller is organized in a menu structure to
provide quick access. As shown in Figure 2, this structure is divided into three levels: categories,
menus, and items. The category, which is the highest level in the structure, can be “Status,”
“Control,” or “Alarm.” The name of each category describes the basic purpose of the menus it
contains. Complete information on the contents of each menu is included in the following
“Keypad/Display Menu Reference” section.

Status Category
Menus in the Status category contain information about the current operation of the RMC controller
and its multiple-unit control groups (if any). The fields in these menu items provide status
information only and cannot be changed with the keypad. The Status category menus are
summarized in Table 4. Status.
Control Category
Menus in the Control category contain set points and parameters that define how the RMC
controller operates. After the password is entered, most fields in these menu items can be changed
with the keypad. The Control category menus are summarized in Table 4.
Alarm Category
Menus in the Alarm category contain current and previous alarm information. The Alarm category
menus are summarized in Table 5.
Display Format
The information stored in the RMC controller’s menu structure can be viewed on the 2-line by 16-
character LCD display. As shown in Figure 3, the current menu is displayed on the top line and the
current item is displayed on the bottom line. The item line contains one or more fields that convey
varying information.

Password Protection
The MicroTech controller includes password protection to guard against the entry of inadvertent
changes. When you attempt to change the value of an adjustable parameter with the keypad, the
controller prompts you to enter the password. If the correct password is entered, the controller will
allow you to make changes as desired. Five minutes after the last keystroke is made, the controller
will disallow further changes until the password is re-entered.
The keypad password for all controllers is the following keystroke sequence: ENTER, ENTER, ENTER,
ENTER. It is not adjustable. See “Keypad Functions” below for more information.
Keypad Functions
The MicroTech controller’s keypad consists of 12 pressure sensitive membrane switches, which are
divided into 4 groups: “Category,” “Menu,” “Item,” and “Action.” See Figure 4. Following are
descriptions of these groups and the keys they contain.

Category Group
Acting like bookmarks in the menu structure, the keys in the Category group provide quick access to
the desired menus. By using these keys, you can minimize scrolling between menus with the keys in
the Menu group (see below). Refer to Figure 2.
Status Key: Any time the STATUS key is pressed, the first menu in the Status category is displayed.
This is menu 1, “RMC Status.”
Control Key: Anytime the CONTROL key is pressed, the first menu in the Control category is
displayed. This is menu 4, “Group Assign.”
Alarms Key: Any time the ALARMS key is pressed, the first menu in the Alarm category is
displayed. This is menu 17, “Units w/Alarm.” Note that when an alarm occurs, the display will
automatically switch to the “Units w/Alarm” menu. You can then use the SWITCH key to return the
display to whichever menu and item it was at before the alarm occurred.
Switch Key: The SWITCH key toggles the display between associated Status and Control category
menu items. It allows you to quickly check a controlled condition against its set point. For example,
by pressing SWITCH when the Group #1 static pressure is being displayed (“Group #1=” item under

12 OM-121
menu 3), the Group #1 static pressure set point will be displayed (“Press Spt=” item under menu 5).
If SWITCH is pressed again, the actual pressure will be displayed again. Note that the SWITCH key
will not work with every menu item. Table 4. Status and Table 4 list the SWITCH key destinations for
all applicable menu items. The SWITCH key has two additional functions: (1) it can be used to return
the display to the menu and item it was at prior to an alarm (see “ALARMS Key” above) and (2) it
can be used in conjunction with the Menu NEXT or PREV key to change the controller the RMC
Panel’s keypad/display is interfaced with (see “Changing the Keypad-Controller Interface” below).
Menu Group
The keys in the Menu group allow you to choose the menu you want to display. Refer to Figure 2.
Prev Key: When the Menu PREV key is pressed, the display will scroll to the previous menu in the
structure. This action will occur regardless of the current menu number. Note that you can “wrap
around” from the first menu to the last menu by pressing the Menu PREV key twice.
Next Key: When the Menu NEXT key is pressed, the display will scroll to the next menu in the
structure. This action will occur regardless of the current menu number. Note that you can “wrap
around” from the last menu to the first menu by pressing the Menu NEXT key twice.
Item Group
After you select a menu, you can choose the item you want to display by using the keys in the Item
group. Refer to Figure 2.
Prev Key: When the Item PREV key is pressed, the display will scroll to the previous item in the
current menu. Note that you can “wrap around” from the first item to the last item by pressing the
Item PREV key twice.
Next Key: When the Item NEXT key is pressed, the display will scroll to the next item in the
current menu. Note that you can “wrap around” from the last item to the first item by pressing the
Item NEXT key twice.
Action Group
The Action group keys allow you to clear alarms or change set points and parameters in the selected
item’s field(s). Note that the password must be entered before any set point, parameter, or schedule
changes can be made. See “Password Protection” above for more information.
Incr Key: When the INCR key is pressed, the entry in the item’s selected field will change to the
next higher value or next available selection. The field being edited will flash until the ENTER or
CLEAR key is pressed.
Decr Key: When the DECR key is pressed, the entry in the item’s selected field will change to the
next lower value or previous available selection. The field being edited will flash until the ENTER or
CLEAR key is pressed.
Enter Key: When the ENTER key is pressed, the entry in the item’s selected field will be locked in.
If the selected item has one field, pressing ENTER also completes the edit. If the selected item has
more than one field, pressing ENTER also makes the next field available for editing with the INCR
and DECR keys. If no change is desired, press ENTER until the desired field is flashing or the edit is
complete. (It is possible to initiate an edit of a multi-field item by pressing the ENTER key. In this
instance, the first field would be left unchanged and the second field would be available for editing.)
Clear Key: The CLEAR key is used to clear alarms and edited (flashing) fields. When a specific unit
controller alarm is in the display, pressing CLEAR will clear the current alarm. (At the RMC Panel’s
keypad/display, you must change the keypad-controller interface to the unit with the alarm to do
this. See below.) When an item field is being edited, pressing CLEAR will restore the field’s previous
entry and end the edit.

OM-121 13
Changing the Keypad-Controller Interface
The RMC Panel’s keypad/display can be directly interfaced with its own controller or remotely
interfaced with any of its associated unit controllers via network communications. The controller
that is currently selected is indicated by the Unit Selection LEDs on the panel face. When the RMC
Panel’s keypad/display is interfaced to a unit controller, it acts identically to the unit’s
keypad/display (see note below).
To shift the interface “down” to the next controller (for example, from Unit #1 to Unit #2), press
SWITCH and then the NEXT key in the Menu group. To shift the interface “up” to the previous
controller (for example, from Unit #2 to Unit #1), press SWITCH and then the PREV key in the Menu
group. Repeat either keystroke sequence until the desired controller is selected. Note that you must
release the SWITCH key before pressing the Menu NEXT or PREV key, and the key stroke sequence
must occur quickly (within 1 second); otherwise, the controller will execute separate, normal
SWITCH and Menu NEXT or PREV key functions.
The controller selection function can “wrap around” from the last to the first controller or from the
first to the last controller. For example, you can change the interface from Unit #8 to the RMC
Panel by pressing SWITCH and then Menu NEXT.
The keypad-controller interface will automatically change back to the RMC Panel five minutes after
the last keystroke is made.
Note: A unit controller’s service mode can be changed only at the unit. You can look at a unit’s
service mode with the RMC Panel’s keypad/display, but the unit controller will not let you change it
remotely. (Caution: This feature was not available with the following applied rooftop unit programs:
95016[-03[and earlier, and 95031[-01[.)
Keypad/Display Exercises
Following are three exercises that will guide you through some typical keypad operations. Note that
often there is more than one way to perform an operation. For example, you can use the Menu group
keys with or without the optional Category group keys to quickly find the menu you want to display.
Changing a Set point
In this exercise, assume that the two VAV rooftop units are operating as Group #1 and the duct
static pressure is too high. The common duct pressure is currently 1.6"WC, and the Group #1 DSP
Set point is 1.5"WC. Using the following procedure, you will change this set point to 1.0"WC and
thus lower the actual pressure.
1. Press CONTROL in the Category key group. The first menu of the Control category is displayed.
This is menu 4, “Group Assign.”
2. Press NEXT in the Menu key group once. Menu 5, “Group #1,” is displayed. The first item of this
menu, “Cntl Temp=,” is also displayed.
3. Press NEXT in the Item key group three times. The “Press Spt=” item is displayed. This is the
Group #1 DSP (duct static pressure) Set point. The default value of 1.50"WC should also be
displayed.
4. Press either INCR or DECR in the Action key group. The controller prompts you for the password.
5. Press ENTER in the Action key group four times. (This is the password.) The “Password
Verified” message is displayed.
6. Press DECR until the set point is 1.00"WC. Notice that the adjustable field flashes during the
change.
7. Press ENTER. The field stops flashing. This means that the new set point is locked in.

14 OM-121
8. Press SWITCH in the Category key group. The actual duct pressure (“Group #1=” item under
menu 3, “Static Press”) is displayed. Now that the set point has been lowered, the pressure
should drop.
Clearing an Alarm
In this exercise, assume that an alarm which requires a manual reset occurred in Unit #1. If the
conditions that caused the alarm are gone, you can clear the alarm from the RMC Panel by using the
following procedure.
Note: When a unit alarm occurs while the RMC Panel is the selected controller, the RMC
Panel’s keypad/display automatically switches to menu 17, “Units w/Alarm.” So to set up
this exercise, change the display to menu 17 by pressing the ALARMS key.
1. The item line of menu 17 shows “#1,” which indicates that there is an alarm associated with
Unit #1. Press ALARMS in the Category key group to silence the alarm horn.
2. Since the alarm is in Unit #1, change the keypad-controller interface to Unit #1 by pressing
SWITCH and then Menu NEXT. The “Unit #1” Unit Selection LED lights indicating that the
keypad/display is interfaced with Unit #1.
3. Press the ALARMS key. The first menu of the unit’s Alarm category is displayed. This is the
“Curr Alarm” menu (rooftop menu 29, SCAC menu 26).
4. With the current alarm in the display, press CLEAR in the Action key group. This clears the
alarm and returns the unit to normal operation. The “#1” alarm indication on menu 17 of the
RMC Panel automatically clears.
Modifying a Schedule
In this exercise, assume that a change in building occupancy requires the units assigned to
Schedule #4 to run from 12:30 a.m. to 5:00 p.m. on Saturday. Currently, they are scheduled to be
shut down on Saturday. Using the following procedure, you will change this schedule accordingly.
(This procedure assumes that the password has previously been entered and the 5-minute
authorization timer has not expired.)
1. With the “RMC Panel” Unit Selection LED lit, press ALARMS in the Category key group. The
first menu of the Alarm category is displayed. This is menu 17, “Units w/ Alarm.”
2. Press PREV in the Menu key group four times. Menu 13, “Schedule #4,” is displayed. The first
item of this menu, “Sun,” is also displayed. Note that you could have started at the beginning of
the Control category of menus and stepped forward to menu 13 by using the Menu NEXT key, but
it would have taken longer.
3. Press PREV in the Item key group three times. (This makes use of the wrap-around capability.)
Menu item “Sat,” is displayed. The default start-stop schedule of 00:00–00:00 should also be
displayed. Each of the four sets of numbers is an adjustable field: start hour, start minute, stop
hour, and stop minute. Note that you could have stepped forward to “Sat” by using the Item
NEXT key, but it would have taken longer.
4. Press ENTER in the Action key group. The second field (start minute) flashes, indicating that it
can be edited. Since the desired schedule is 00:30–17:00, the first field (start hour) does not need
to be changed. By pressing ENTER instead of INCR, you can bypass this field.
5. Press INCR until the start minute field is 30. Notice that the adjustable field flashes during the
change.
6. Press ENTER. The second field stops flashing, and the third field (stop hour) starts flashing. This
means that the new start minute is locked in and the stop hour can be edited.
7. Press INCR until the stop hour field is 17.
8. Press ENTER. The third field stops flashing, and the fourth field (stop minute) starts flashing.

OM-121 15
9. Since the stop minute field does not require editing, press ENTER again. The fourth field stops
flashing, thus completing the edit. Note that the same result could have been accomplished by
pressing the CLEAR key instead of the ENTER key.
Keypad/Display Menu Reference
The following tables show every menu, item, and field in the menu structure of the RMC controller.
These menus and items can all be displayed with the keypad/display.
Status Menus
Table 4. Status lists all possible menus and items in the Status category. The table’s range column
lists all possible values for each item. Following are brief descriptions of the Status category menus.
RMC Schedule Status
Menu 1, “RMC Status,” tells you the current status of the RMC Panel’s four schedules. You can
assign a schedule to one or more of the units associated with the panel. For more information, see
the “Scheduling” section in the “Operator’s Guide” portion of this manual.
Control Temperature
Menu 2, “Control Temp,” tells you the current Control Temperature for each of the four multiple-
unit control groups. This Control Temperature is the conditioned value (minimum, maximum, or
average) that the RMC controller writes to each unit assigned to the group. The RMC controller
calculates the Control Temperature from the return or space temperature it reads from each unit in
the group. For more information, see the “Multiple-Unit Control Features” section in the
“Description of Operation” portion of this manual.
Static Pressure
Menu 3, “Static Press,” tells you the current duct static pressure for each of the four multiple-unit
control groups. This pressure is the conditioned value (minimum, maximum, or average) that the
RMC controller uses to control each VAV unit assigned to the group. The RMC controller
calculates the common duct static pressure from the duct pressure it reads from each unit in the
group. For more information, see the “Multiple-Unit Control Features” section in the “Description
of Operation” portion of this manual.

Control Menus
Table 4 lists all possible menus, items, and adjustable fields in the Control category. The table’s
range column lists all possible values for each adjustable field. Following are brief descriptions of
the Control category menus.
Group Assignment
Menu 4, “Group Assign,” allows you to assign units to the RMC Panel’s four multiple-unit control
groups. (A multiple-unit control group is a set of two to eight units that operate as though they were
one large unit.) If the RMC Panel is being used for remote monitoring or scheduling only, all
parameters in this menu should be set to “NA.” For more information, see the “Multiple-Unit
Control Features” section in the “Description of Operation” portion of this manual.
Group #1 Setup
Menu 5, “Group #1,” contains parameters that are used to set up the first multiple-unit control
group. Two to eight units can be assigned to this group (see “Group Assignment” above). If the
RMC Panel is being used for remote monitoring or scheduling only, no parameters in this menu
need to be set. For more information, see the “Multiple-Unit Control Features” section in the
“Description of Operation” portion of this manual.
Group #2 Setup
Menu 6, “Group #2,” contains parameters that are used to set up the second multiple-unit control
group. Menu 6 is similar to menu 5; see “Group #1 Setup” above for more information.
Group #3 Setup
Menu 7, “Group #3,” contains parameters that are used to set up the third multiple-unit control
group. Menu 7 is similar to menu 5; see “Group #1 Setup” above for more information.

OM-121 17
Group #4 Setup
Menu 8, “Group #4,” contains parameters that are used to set up the fourth multiple-unit control
group. Menu 8 is similar to menu 5; see “Group #1 Setup” above for more information.
RMC Schedule Assignment
Menu 9, “RMC Schedule,” allows you to assign one of the RMC Panel’s four schedules to each unit.
It is not necessary to assign an RMC schedule to a unit; for example, you could have an external
time clock start and stop a unit. For more information, see the “Scheduling” section in the
“Operator’s Guide” portion of this manual.
Schedule #1
Menu 10, “Schedule #1,” contains the internal scheduling parameters for the first RMC controller
schedule. This schedule, which is similar to the one in each unit controller, can be assigned to any
unit associated with the RMC Panel (see “RMC Schedule Assignment” above). For more
information, see the “Scheduling” section in the “Operator’s Guide” portion of this manual.
Schedule #2
Menu 11, “Schedule #2,” contains the internal scheduling parameters for the second RMC
controller schedule. Menu 11 is similar to menu 10; see “Schedule #1” above for more information.
Schedule #3
Menu 12, “Schedule #3,” contains the internal scheduling parameters for the third RMC controller
schedule. Menu 12 is similar to menu 10; see “Schedule #1” above for more information.
Schedule #4
Menu 13, “Schedule #4,” contains the internal scheduling parameters for the fourth RMC controller
schedule. Menu 13 is similar to menu 10; see “Schedule #1” above for more information.
Holiday Date
Menu 14, “Holiday Date,” allows you to schedule 14 holiday dates. Each date can be assigned a
duration from 1 to 31 days. On each day of the holiday period, the holiday schedules entered under
menus 10, 11, 12, and 13 are used. For more information, see the “Scheduling” section in the
“Operator’s Guide” portion of this manual.
Time and Date
Menu 15, “Time/Date,” allows you to adjust the current time, day, and date. You can also set up the
controller for daylight-saving time. For more information, see the “Scheduling” section in the
“Operator’s Guide” portion of this manual.
Service
Menu 16, “Service,” contains controller setup and service related items. For more information, see
the following “RMC and Unit Controller Setup” section. The last item, “IDENT=,” displays the
RMC controller’s program code.

Alarm Menus
Table 5 lists all possible menus, items, and adjustable fields in the Alarm category. The table’s
range column lists all possible values for each item. Following are brief descriptions of the Alarm
category menus.
Units With Current Alarms
Menu 17, “Units w/Alarm,” tells you which units currently have alarms. Each unit is assigned two
characters on the item line; for example, “#1.” If a unit alarm or a loss-of-communications alarm
exists for a particular unit, its number will be displayed. The number will be flashing if the current
alarm is a comm loss or fault alarm. If no alarms exist in the network, the item line will be blank.
For more information, see the “Alarm Monitoring” section in the “Operator’s Guide” portion of this
manual.
Alarm History
Menu 18, “Alarms,” tells you what the last eight alarms were and when they occurred. Both current
and previous alarms are displayed. Each alarm is displayed as a set of two items. The first item
