The GR03/GR3 controller user manual can be used to set up all stand-alone and BMS installations which will operate with standard environmental conditions. Do not attempt to adjust the control parameters without having read and understood the manual. The NRL unit arrives with a basic operating program ready to start up as soon as the building utilities are completed. The GR3 user manual allows you to understand the basic functions and set points required to operate the system. For more complex systems the GR3 after service manual is available to provide additional information. In the interest of brevity the GR03/GR3 may be described as GR3 where it is appropriate.
