All the boards feature a byte microprocessor, and consequently the calculation power and operation processing speed have been significantly increased. As for all the pCO series controllers, pCO3 comes in a plastic case that ensures a high index of protection and reduces the risk of electrostatic discharges due to incorrect handling. In addition, assembly is simplified by the DIN rail mounting system, allowing significant saving in wiring and assembly times. Given the increasing demand for integration, pCO3 can interface with many of the most commonly-used serial communication standards, and, using optional cards, can be integrated into the most widespread BMS systems.

The co ntroller. Connection between the terminal unit and main board is necessary. T he co ntroller is linked to a graphic. In general, th e cont roller is operated as follows. D uring t he. Upo n critical failure s, t he complete system will shut down with. For cert ain compo nent failures, the applicable feature is disabled to insure safe.
For example, when compressor failure occurs, t he failed compressor shall be. The system will not use that function until. Page 9 of T he con troll er also keep s th e history o f last alarms after. Maximum 16 units can be. Eac h controller is self independent. When used on p -LAN. Network, each unit must have same software revision and set to maintain same set p oints and.
Th e unit U01 must be set for the total units o n the network. U 16 are define as. The Master always starts first to maintain the temperatu re and humidity set points. Slave is kept on standb y as long as t he Master is able to ac hieve the set points within the dead. When the M aster fails to do so, it calls in the Slave t o assist.
Then both units wil l be. The Slave drop s out when set points are achieved. When t he Master fails by any of. Master is recovered.

Contents 1. Features of the program The main characteristics of the system are the following: display and control of the values measured; the number and type of devices controlled can be configured; alarms highlighted on the display and by audible signal buzzer ; configuration parameters number of devices, times, etc. Description Displays the alarms, manually resets the alarms and mutes the buzzer. If the button is lit up red , it means that at least one alarm is active.
