ARTC-SVX005A-EN 33
This is the version of the interface software currently
loaded in the system. This number consists of four sets of
two-digit numbers.
• The first two sets indicate major and minor software
revisions.
• The third set has an initial value of ‘00.’ If this is a
special edition of the software, this number will be
designated something other than ‘00.’ See Figure 19,
p. 32
• The fourth number indicates the beta software revision
sequence.
Middle Section Functions
Chiller Status. Features in the middle section include
status indicators and controls for the chiller/heater system
as a whole:
• Chiller/heater temperature set points for cooling and
heating
• Chiller/heater system cooling in and out water
temperatures
• Chiller/heater system heating in and out water
temperatures
• Chiller/heater system source sink in and out water
temperatures
• Chiller/heater system power on or power off status
• Chiller/heater system operational mode: cooling,
heating, or simultaneous
Bottom Section Functions
Module and Compressor Status. Features in the bottom
section include:
System On
This button powers the chiller/heater (and all its modules)
on and off via a software switch. The button should be
pressed for few seconds to power the chiller/heater.
Cool and Heat Demand Comp / %
This is the cooling and heating demand value in terms of
the number of requested compressors as well as
continuous value as a percentage. A bar graph
representation of cooling or heating demand is adjacent to
the numeric value.
Setup
This is the number of chiller/heater modules set up at the
factory.
Online
This is the number of chiller/heater modules currently
communicating with the master microprocessor
controller, including the master module.
Evaporator / Condenser / Source
This is the pumps operating state. A green LED indicates
that corresponding set of pumps is being requested by the
chiller/heater; otherwise pumps are not requested.
Cool / Heat / Simult
This is the number of modules currently running in
cooling, heating, or simultaneous mode, in terms of
number of modules and number of compressors.
