Johnson Controls Unitary Products 5
D Units will come with the new state of the art Simplicity SE
(Smart Equipment) control system. The new unit control
incorporates the best of the already proven Simplicity™ unitary
controls and creates a more robust, intelligent control. The goal
of this control is to utilize cutting edge technology making the
equipment easier to install, operate, and service. All units are
Factory commissioned, configured, and run tested.
Versatile - The Simplicity SE control can be configured to use
with a standard thermostat (easy to connect screw terminals), A
zone sensor, or can be setup to communicate with multiple BAS
communication protocols to integrate with building automation
systems.
Reduce field installed complexity - Each unit will comes
equipped with factory installed supply air, return air, and
outdoor air temperature sensors providing key temperature
readings thus reduce field installed complexity.
On-board USB Port - The new control comes with a long list of
features including data logging, current and previous system
faults and software update capabilities using the on board USB
port and common flash drive. Energy use monitoring
capabilities allow custom tailoring to allow a system to work
more efficiently at all times and occupancy levels. Self test and
start-up reports also available from the board VIA the USB port.
Embedded LCD Display - The board has a easy to read, built-
in LCD display and easy to use navigation joystick and buttons
allowing the user to quickly navigate the menus displaying unit
status, options, current function, supply, return and outdoor
temperatures, fault codes and other information.
Safety Monitoring - The control monitors the outdoor, supply,
and return air temperatures and the high and low pressure
switch status on the independent refrigerant circuits. On units
with heating the gas valve and high temperature limit switches
are monitored on gas and electric heating units. The control
also monitors the voltage supplied to the unit and will protect
the unit if low voltage due to a brown out, or other electrical
issue occurs.
Low Ambient - An integrated low-ambient control allows units
to operate in the cooling mode down to 0°F outdoor ambient
without additional components or intervention. Optionally, the
control board can be programmed to lockout the compressors
when the outdoor air temperature is low or when free cooling is
available.
Anti-Short Cycle Protection - To aid compressor life, an anti-
short cycle delay is incorporated into the standard control.
Compressor reliability is further ensured by programmable
minimum run times. For testing, the anti-short cycle delay can
be temporarily overridden with the push of a button.
Fan Delays - Fan on and fan off delays are fully programmable.
Furthermore, the heating and cooling fan delay times are
independent of one another. All units are programmed with
default values based upon their configuration of cooling and/or
heating capacity.
Nuisance Trip Protection and Three Strikes - To prevent
nuisance calls, the control board uses a three times, you're out
philosophy. The high, low-pressure switch, anti-freeze
protection, low voltage or heating high limit must trip three times
within two hours before the unit control board will lock out the
associated compressor. The same safety must trip three times
before a hard lockout will occur.
E Robust design - Each unit is designed with an embossed
top to increase structural support and ensure rigidity. The unit
has a powder paint exterior finish including a industry leading
1000 hour salt spray rating. All units are painted with a long
lasting, powder paint that stands up over the life of the unit.
