The Bard Telcom Climate Watch System
The Bard Telcom ClimateWatch System (TCS22) is a building
monitoring and direct digital control system for use with one or two
(2) Bard 1-1/2 ton through 6 ton Wall-Mount air conditioners. The
Bard TCS22 allows you to remotely monitor (24-hours a day) and
digitally control The Wall-Mount™ air conditioning unit based on
user-defined control strategies. The sensing devices mounted
within The Wall-Mount™ unit function to input analog data such
as temperature as well as digital data such as air flow, compressor status, or filter status. The system provides monitoring and
sending several alarms with the built-in capability of automatically
dialing out to a pager or line printer to report alarm conditions.
The complete “turn key” telcom system consists of a state of the
art TCS22 direct digital controller, Climate Watch software, two (2)
Bard Wall-Mount air conditioners and a special control module “V”
that is factory mounted within the Bard Wall-Mount air conditioner.

VENTILATION OPTIONS
WALL-MOUNT ECONOMIZER ACCESSORY
1. Economizer to provide “free cooling” when the outside temperature is cool enough to provide needed cooling
without running the compressor. This DDC economizer is available as a factory installed option in models WA182
to WA721 and models WL182 to WL602. Economizer model nomenclature is “D” for factory installation. An example
would be WA372-A10DXXXXV. Decision for free cooling can be based on enthalpy or dry bulb temperature only.
INVERTER ACCESSORY (Field supplied)
1. Inverter can be used to provide forced air cooling through The Wall-Mount’s economizer system when a power failure occurs. To utilize
the power failure management portion of the TCS22, a field-supplied inverter and battery back-up system should be installed in the
telecommunication shelter.
ENGINEERING SPECIFICATION GUIDE
Furnish and install a one piece, factory assembled, prewired, and pretested DDC controller. The units will have the following features and be
manufactured by Bard Manufacturing Company, Model No. TCS22 ________.
1.0 Enclosure Construction The enclosure shall be constructed of 20 gauge cabinet with 16 gauge door prepainted steel. Cleaned, rinsed, sealed and dried before the
polyurethane primer is applied. The cabinet is handsomely finished with a baked on textured enamel which allows it to withstand 1000 hours
of salt spray exposure.
2.0 Communication Remote communication options with the controller available via modem or ethernet network module.
* Modem - the controller shall include a modem to allow remote communication and control of the controller. The modem shall be suitable
for asynchronus communications at 9600 baud (optional) ______.
* Ethernet Network Module - the controller shall include an ethernet card and all software to allow remote communication and control of the
controller (optional) ______.
3.0 DDC Controller A System Controllers (SC) for the air conditioning units shall be based upon multi-layer printed circuit boards in metal enclosures, with 16 bit
microcontrollers, battery backed calendar clock chips, two communication ports on board RS232 and RS485, a minimum input resolution of
10 bits and minimum scan time of 1 second, and minimum communication speed of 9600 baud.
Each SC shall have 16 universal inputs, 12 normally open relay outputs, and eight 0-10 volt DC analog outputs. The universal inputs
shall be pre-programmed to interpret up to four contact closures in conjunction with a resistor ladder to any single input; they shall also
read 0-5 volt DC and 4-20 ma inputs as standard, and have built-in look up table of 3,000 ohm thermistors. Inputs may be used for
temperature, pressure, flow, voltage, current, frequency and for pulse counting.
Relay outputs may be configured for maintained, momentary, or pulse width modulation operation, with or without interlocks, and with
or without verification of status of the controlled device. Outputs shall be rated for 5 amps at 24 volts. Analog outputs shall be suitable
for 5 ma over 0-10 volt DC, referenced to ground.
Object oriented firmware shall be embedded in each SC, so that specific applications can be configured by linking preprogrammed
objects. Objects shall include PID control, logic, schedules, timers, dynamic and static trending, optimum start, demand management,
calculated points, remote points, broadcast, and event logging. Multiple instances of each object shall be available, so that for
example up to 256 logic gates may be utilized. No high level language shall be required for configuring the SC. Configurations shall
be stored in non-volatile EEPROM memory, and shall be retained indefinitely through power outages.
The hardware clock in each SC shall maintain time and date regardless of power failures. The SC shall automatically spring forward
and fall back at the onset and conclusion of daylight savings time.
LEDs shall indicate the status of each binary output, and the status of the communication busses. Four LEDs shall be available on
each SC for user configurable alarm/indication.
SC shall have Molex type connectors for inputs, outputs and power, and two part terminals for communication wiring, so that a
controller can be replaced by unplugging the connectors and plugging them into a replacement.
