6 COMMISSIONING FUNCTIONS

The topics in this secon are advanced topics for control technicians and engineers. These topics cover procedures for the inial

EZstat setup.

The EZstat commissioning funcons are values and sengs that are entered during the installaon and commissioning of a

controller and the equipment it is controlling. Typically these funcons do not change aer the installaon and commissioning

process.

To set up the commissioning funcons, you will need the following informaon:

• Informaon about the equipment

• The sequence of operaon for the equipment

• The building automaon system plans for controllers that are part of a network.

Users may change the occupied heang and cooling setpoints without accessing the commissioning funcons. This procedure

is covered in the topic User funcons.
