7.2.4.5 Scheduling
Daily (from Monday to Sunday) schedules of Occupied/
Unoccupied state can be set and send to the RCB board.
7.2.4.6 Alarming
Alarms generated from RCB board will be received and
reported by Alarm management in the Supervisory Controller.
You can configure alarms properties such as:
• Alarm repeat rate
• Alarm type
• Alarm category
• Alarm displayed message
• Alarm monitoring flag
The Alarms generated from the Supervisory Controller for the
RCB application are the following:
• Control Temp High
• Supply Temp High
• Return Temp High
• Control Temp Low
• Supply Temp Low
• Return Temp Low
You can set the following attributions for each of the alarms
above:
• Alarm repeat rate
• Alarm delay
• Alarm type
• Alarm category
• Alarm displayed message
• Alarm monitoring flag
For the alarms generated by the RCB board, any reset or clear
actions you performed in the Supervisory Controller will be
forwarded to the RCB.
7.2.4.7 Real Time Clock Updates
Please refer to Section 7.2.3.7,Real Time Clock Updates.
7.2.4.8 Hand-Held Terminal Support
Please refer to Section 7.2.3.8,Hand-Held Terminal Support.
7.2.5 MultiFlex RTU
Similar in design to the MultiFlex combination input/output
boards, the MultiFlex RTU board is designed specifically for
operating package rooftop HVAC units as part of a
Supervisory Controller or REFLECS BCU building control
system. The MultiFlex RTU is designed to be a replacement
for the previous generation ARTC, and is 100% compatible
with all legacy Supervisory Controller and BCU systems.
The MultiFlex RTU board has 16 analog inputs, 8 relay
outputs and 4 analog outputs. Most of these I/O points are
reserved for sensors and input devices required to read
environmental data (such as space and supply air
temperature) and control all output devices that control the
environment (such as heat/cool stages and dampers). Both
auxiliary inputs can be configured for a variety of sensor types
including any type of linear sensor. For linear sensors, the
auxiliary inputs can be configured as Satellites. By doing this,
the minimum and maximum voltage and minimum and
maximum Engineering Unit parameters are user configurable
for these inputs. The RTU relay outputs are rated for line
voltage (240VAC).
The RTU board controls the rooftop unit directly with its built-
in heating, cooling, and humidity control algorithms. It may
operate in stand-alone mode, or it may interface with a
Supervisory Controller or BCU to control the store
environment in zones and pass along logging and alarm
information.
The MultiFlex RTU has its own installation and operation
manual (P/N 026-1706).
NOTE
NOTE: The RCB does not have the
capability of resetting individual
alarms. All alarms on the RCB will be
reset or cleared by the RCB if anyone
is reset or clear the alarms in the
Supervisory Controller.
