iCOM Control Training and Service Manual

Freecooling and Dual cooling will operate in the same manner as chilled water with the supervision of the Supply Limit, again showing different valve positions on the units

If in a Freecooling or Dual Cooling unit if the limit of the coil operation is detected (no free cooling or no CW available) the valve will close off and unit will become DX operation in the system.

Networking and Functions

Unit 2 Unit (U2U) Communications by networking will allow the following functions to be placed into operation when the requirements exist. The user must install the correct hardware and properly program the units for the functionality.

In the iCOM Network the owner may perform the following functions:

The Teamwork Mode functions, which allow multiple stages of Cooling/ Heating and/ or Humidification/ Dehumidification. The ability to prevent the units fighting is included in this feature.

The Lead/ Lag function, which allows one or more units to be set as “Running and Standby” for activation in case of an alarm. This also has the ability to be programmed in a rotation for assurance of functional standbys.

The Cascade function, which allows additional units to be staged on based on the temperature or humidity requirement.

Understanding the iCOM Network setup process:

To setup a system network with the iCOM control requires a complete understanding of the control processes and parameter programming to insure the proper functional operation without incident. To insure the setup is correct and that the operation will function as selected you need to map both the room layout and the unit setup. First, read and record all programmed settings in all of the single units. Second, document the network parameter settings that are needed and identify the numerical order of the units to be networked. The order of the setup process is very important.
