Note this means that although a LAN and or internet connection is necessary for full monitoring and adjusting parts of the SLIC system once it is set up no LAN or internet is required for proper functioning of the heating system VSLIC SOFTWARE FOR FULL ACCESS AND ADJ USTM ENT The SLIC control box does not contain any user adjustments or displays This is because it is designed for access using a computer over a network Each SLIC is connected to a Local Area Network LAN and can be monitored and adjusted by VSLIC software see below from any computer on that network If the LAN is connected to the internet the same VSLIC software may be used for remote operation over the internet as well The software program called Virtual SLIC exe aka VSLIC is provided by SolarLogic and presently runs only on Windows based PCs Future updates will be compiled for other operating systems This software can be installed on multiple computers at any network location local or remote and used to monitor and adjust the SLIC system from different locations Typically the installer several occupants and SolarLogic may be granted access from different network computers Access to an installed SLIC is controlled by a combination of the VSLIC software the SolarLogic central server and the SLIC itself through user IDs and passwords More than one user can be logged on to a SLIC at the same time This feature makes it possible for the system owner and the installer
7. VSLIC SOFTWARE The SLIC SolarLogic Integrated Controller is a combination hardware software system controller typically installed to control Solar Combisystems These are heating systems that have several different heat sources that all provide heat to many different end uses The SLIC replaces all conventional controls adds intelligent logic and provides a host of internet delivered bene ts such as remote monitoring diagnostics data logging and remote system operation over the internet The SLIC uses a le with instructions provided by the SolarLogic Assisted Solar Heating Design SLASH D software for information about the heating system so it starts up knowing exactly how to operate the system eliminating the need for programming and lengthy set up procedures SOLARLOGIC SLIC olan opc imeorated Curtretiert FIGURE 1 SLIC GEN II Control Box The SolarLogic Integrated Control SLIC is typically installed to control all the heating equipment in a solar heated home SOLARLOGIC 256 2012 SolarLogic LLC M ANUAL HEATING CONTROL USING ROOM THERM OSTATS The SLIC Gen II system can be operated by the occupants of the building without computer access using only the room thermostats provided by SolarLogic Any occupant can turn the knob on thermostat up or down to increase or decrease the target temperature in that heating zone Also the switch at the bottom of the thermostat can be set by any occupant to Solar Only Nor
