Chiller HeatPump Rack
Complete machine architecture for Chiller, Heatpump and Compressor Rack applications:
- 4 circuits
- 6 compressors per circuit 1 and 2
- 1 compressor per circuit 3 and 4
- Common or split condensing fans
- Electronic expansion valve
- Dynamic IO allocation
- Local / remote HMI
Rear-door heat exchanger - RDHx
Rear Door Heat Exchanger (RDHx) is a server rack door equipped with fans and chilled water pipes. Free Advance manages the internal rack temperature by controlling both the fans and the water valve integrated into the door.
Parametric AHU
A complete ready-to-use application which provides complete control of the major Air Handling System functions and modules currently available on the market. The application, developed with a block programming approach, features an architecture for quick and easy configuration.
Cold Room
Cold Room is an application targeting the Eliwell programmable controller family which can control functions in both static and ventilated cold rooms, including combined temperature and humidity control.
Universal Controller
Universal Controller with 7 generic regulators (Four in temperature and three in pressure); each of those can be configured as PI, output sequencer, super heat, delta between two probes, maximum function between two probes, configurable PI limits, weekly scheduler, and low and high temperature/pressure threshold alarms.
Short guide on how to dynamically manage the Free Optima double row display.
This HowTo guides you through the creation of a multi-language HMI. It is structured in a powerpoint presentation and it also includes a Project sample.
Starting from Free Studio Plus v. 1.4 and from 596.12 and 668.12 FW, two new functionalities have been added:
- It is possible to have a faster booting time disabling the expansions not used (10 sec for each missing expansion).
- It is possible to force a Modbus Master (MBM) configuration as slave using a parameter.
Step by step guide on how to show SET variable list with AVP1000, AVP1100, AVP1200 and AVP1300.
It is a tool to compile and program the controller using command line. It is located in the Device folder of Free Studio Plus setup installation.
It could be useful in a production line or in system where there is a shell command line.
