NOTE
6 COMMISSIONING FUNCTIONS
The topics in this section are advanced topics for control technicians and engineers. These topics cover procedures for the initial
EZstat setup.
The EZstat commissioning functions are values and settings that are entered during the installation and commissioning of a
controller and the equipment it is controlling. Typically these functions do not change after the installation and commissioning
process.
To set up the commissioning functions, you will need the following information:
•
Information about the equipment
•
The sequence of operation for the equipment
•
The building automation system plans for controllers that are part of a network.
Users may change the occupied heating and cooling setpoints without accessing the commissioning functions. This procedure
is covered in the topic
User functions
.
