The electronic controller enables:

1. compressor modulation and / or staging based on suction pressure;

2. TCP/IP Ethernet with web server functionality allows monitoring and configuration of

controllers through a standard web browser;

3. alarm messaging by email;

4. fan speed control if an Alco Controls FSP150 fan speed driver is installed.

The controller has been pre-programmed with a number of parameter values that are most likely

correct. Individual installation requirements however may make it necessary to alter parameter

settings.

The control target of the compressor controller (1) is to maintain the suction pressure at a

defined value by varying the available compressor capacity.

The control target of the condenser controller (2) is to maintain the condensing pressure at a

defined value. This is done by varying the fan speed, if fan speed control is installed.
