ModulAiR Advantages
ModulAiR A/C’s are created by combining quantity
two CyberONE single compressor 3.5, 5, 8 or 10 ton
systems to create quantity one dual compressor 7, 10, 16
or 20 ton system. The result is a large tonnage system in
a very compact foot-print that solves difficult rigging
applications.
Small Elevator? Easy Rigging:
Many service elevators are too small to accomodate the
rigging of typical 1-piece computer room A/C cabinet. As
a result, the historical solution to this rigging problem, has
been to field “cut-down and disassemble”, and then field
“reassemble” the air conditioner. This historical approach
is not only time consuming and costly to the owner, it is
also very risky to the long-term reliable operation of the
air conditioner. ModulAiR units are designed to be the
cost saving, reliable solution to these difficult rigging
problems.
ModulAiR Systems Offer Outstanding Benefits

Alarm History:
The A-Tech-20 controller provides
users with a recorded history of the
last 25 alarms, including the time and
date of the alarm.
CONTROL INPUTS / OUTPUTS:
The A-Tech-20 is capable of both
digital (on/off) and analog (proportional
integral, PI) input and output
device control. Prior to shipment,
each ModulAiR unit's A-Tech-20 is
factory program configured to match
the unit's system operational requirements:
Digital (On/Off) Outputs:
• 2 (two) Cool (if applicable)
• 2 (two) Reheat/Heat
• 1 (one) Humidification
Analog (0-10 Vdc) Outputs:
• 1 (one) Cool
• 1 (one) Reheating/Heat (opt.)
• 1 (one) Humidification (opt.)
Temperature Anticipation:
The A-Tech-20 incorporates a selfcalibrating
and self-adjusting control
logic that adjusts the response of the
SATS air conditioner to changes in
temperature and humidity. The
system provides premium setpoint
accuracy while controlling the room
conditions rate of change, minimizing
the equipment energy consumption
and maximizing the system’s
operating life and reliability.
Remote Stop / Start:
Included in the system's electrical
control circuit shall be a 2-pin
terminal connection for remote stop /
start of the ModulAiR air conditioner
by a remote source.
POWER LOSS RESTART:
In the event of a loss of power to the
system, the A-Tech-20 can be
configured for Automatic or Manual
Restart. The A-Tech-20's nonvolatile
memory enables the system
to restart when power is restored,
without the loss of the "last" stored
set points and other system configuration
settings.
Sequential Load Activation:
To minimize the total in-rush current
loads during system start-up/restart,
the A-Tech-20 controller can be
configured for time-delay sequence
start-up. The user can designate
specific unit restart time-delays, as
well as, each unit's respective
compressor, electric heater and/or
humidifier. Unit restart delay can be
adjusted from 0 to 10 minutes. Unit
compressor, electric heater and/or
humidifier restart delay can be
adjusted from 0 to 60 seconds.
Recovery Delay:
After a power loss, the A-Tech-20's
Recovery Delay feature allows the
ModulAiR A/C to operate without
initiating any high or low temperature
or humidity alarms for a delayed
period. This feature allows the A/C
time (15 to 60 minutes adj.) to "pulldown"
the conditioned space's load
without nuisance alarms during initial
start-up or power loss restart.
COMPRESSOR OPERATIONS:
Short cycle protection:
Each compressor is protected from
frequent compressor cycling through
the A-Tech-20's minimum compressor
ON and minimum compressor
OFF short cycle timers.
Cold Start Time Delay:
Each compressor of a DX Split
system is protected from liquid
slugging through the A-Tech-20's
Cold Start compressor time delay.
The Cold Start timer delays, and
therefore, overrides the system's
refrigerant low suction pressure
Guide Specifications - Microprocessor Control Options
3-7

Microprocessor Controls - A-Tech-20
Guide Specifications - Microprocessor Control Options
switch during system start-up. This
allows the system time to build
sufficient discharge pressure during
cold weather start-up.
Pump-Down Cycle:
The A-Tech-20 is pre-programmed
for a one-time refrigerant system
pump-down cycle upon compressor
shutdown on all split DX systems.
This assists in the prevention of
liquid slugging at start-up/restart.
SECURITY:
Multiple security levels prevent
unauthorized adjustment of critical
system parameters. The user may
select a four-digit password for
setpoint and configuration changes.
Keypad Lockout:
The A-Tech-20 includes a selectable
Keypad Lock-Out feature that
prevents unauthorized users from
making changes to system setpoints
and settings available directly from
the multi-function keypad/display.
Keypad Lock-Out eliminates the
need for stat-guards.
DIAGNOSTICS & SERVICE MODE
The A-Tech-20 incorporates a
unique self-diagnostics algorithm that
continually tests system functions
and hardware operation. In the
event of such a failure, the user will
be alerted to the condition via a
visual and audible alarm.
Control Board:
Initiates a self-test of the control
system.
Input diagnostics:
All system inputs and input devices
are continuously monitored for
proper operation.
Output diagnostics:
(Service Mode)
Major component functionality can
be tested by manually turning
components ON and OFF from the
A-Tech-20 control panel. Select
output devices that can be manually
tested include (if applicable):
• Compressor 1 or 2 • CW Valve
• Blower Motor • HW Valve
• Humidifier • FC Valve
• Heat 1, 2 or 3 stgs • AWS Valve
• Summary Alarm • Liq-Line Solenoid
• Custom Alarm 1 • GC Pump Enable
TIME CLOCK & NIGHT SET-BACK
The A-Tech-20 includes both Time
Clock and Night Set-Back occupied/
non-occupied energy saving modes.
These features enable the user to
customize each unit's daily 5-day/
weekly and 2-day/weekend operational
schedule.
Time-Clock Feature:
The Time-Clock feature enables the
user to create an automatic time
schedule for the unit to be allowed
ON. The Time-Clock 5-2 day
schedule allows the user to limit unit
operation to occupied periods only.
Night Set-Back Feature:
The Night Set-Back feature enables
the user to create a schedule for
automatic relaxing of the unit's
temperature and humidity control set
points. For example, during the
space occupied periods of 7am to
6pm, the unit operates at a temperature
setpoint of 72°F. Then, during
the space unoccupied periods of
6pm to 7am the next morning, the
temperature setpoint automatically
"relaxes" to 77°F. The Set-Back
schedule resets again after 7am that
morning where the temperature
setpoint changes back to 72°F for
Day Time Operation.
Override Feature:
During the unoccupied time cycles,
the user can temporarily "override"
the Time-Clock and/or Set-Back
features. The user can override
these functions for a time duration of
1 to 6 hours.
CyberLAN
Networking Options
MULTI-UNIT "N+1"
SEQUENCING
(Optional)
AC-1 AC-2 AC-3
(Master)
AC-4 AC-5 AC-6
(Standby)
Critical control applications can
incorporate the A-Tech-20's Cyber-
LAN multi-unit sequencing program
logic, where under an A/C failure
condition, the A-Tech-20 will automatically
initiate the unit operation of
a designated standby/backup unit.
Multi-Unit Sequencing:
Multiple CyberAiR air conditioners
incorporating A-Tech-20 controls can
be configured in groups of up to 6
(six) units to allow for "N+1" redundancy/backup
critical application
operation.
The "N" in N+1, represents the
number of concurrent units in an On-
Line Operational Mode with 1(one)
unit in a standby mode. The value of
"N" can range from 1 unit to a
maximum of 5 units with a minimum
and maximum of quantity 1 unit in
standby mode.
3-8

Microprocessor Controls - A-Tech-20
To allow for equal unit runtime and/or
to ensure unit operation, the A-Tech-
20 can be configured for automatic
timed and/or manual lead-lag of
standby unit operation.
The CyberLAN Multi-Unit Sequencing
control logic shall automatically
initiate the current standby unit upon
a user selectable system failure
alarm condition.
The A-Tech-20 is programmed to
automatically change from current
primary unit operation to secondary
standby unit operation via three
methods:
1) Manual ChangeOver
2) Automatic Timed (1-30 days)
3) Automatic ChangeOver on Unit
Failure (if applicable):
• High Temperature
• Low Temperature
• High Humidity
• Low Humidity
• High Head Press
• Low Suction Press
• Sensor Failure
• Loss of Air Flow
• Dirty Filter
• Leak Detection
• Smoke Detection
• Firestat
• GC Pump Failure
• Comm. Failure
Factory defaults set a "logical" active/
inactive state for the alarms. This is
to limit "nuisance" type alarms that
may occur because of conditions
inherent to a particular application or
system and that are not critical to the
operation of the system.
(For example: If Low Humidity is not
critical to a particular application, and
therefore, the A/C unit is not equipped
with a Humidifier, the Low Humidity Alarm
can be set to an inactive state.)
Multi-Unit Network Grouping
Interconnect Cable Options:
• 75 ft. cable length (standard option)
• 150 ft. cable length
Capacity Assist-Mode:
(Additionally Optional)
In addition to switchover via manual,
automatic timed or failure, the
CyberLAN Multi-Unit Sequencing
“Capacity Assist-Mode” can initiate
switchover to standby unit operation
to assist in the temperature and/or
humidity control of the space.
Remote Wall Mounted
Capacity Assist T/H Sensor
Sequence of Operation:
The optional Capacity Assist Mode
includes quantity one remote wall
mounted Capacity Assist-Mode T/H
Sensor with interconnect cable. This
single capacity assist remote T/H
sensor controls all N+1 units in the
respective CyberLAN Group. To
establish a single point of control
reference, the CyberLAN Group’s
temperature and humidity set point is
determined by the Master Unit’s
(U1’s) A-Tech-20 setpoints. Therefore,
each of the current on-line units
of the CyberLAN Group operate and
control space temperature and/or
humidity based on the Master Unit’s
(U1’s) TEMP and HUMID SETPT in
respect to their individual deadband.
Capacity Assist Sensor Cable Options:
• 75 ft. cable length (standard option)
• 150 ft. cable length
The current standby unit is enabled
when the actual space temperature
or humidity rises or falls to a condition
equal to the Master Unit’s (U1’s)
setpoint plus dead-band plus stage
differential (if appl.) plus Capacity
Assist Differential.
(Note: As standard, each unit of a
CyberLAN Group incorporating Capacity
Assist Mode additionally includes its own
standard unit mounted return air T/H
sensor. If the Capacity Assist Sensor or its
communications cable were to fail, Multi-
Unit & Capacity Assist Mode operations will
be automatically disabled, and the N+1
Units will perform as stand-alone systems.
CyberLAN - REMOTE
COMMUNICATIONS
