5 - PRO-DIALOG PLUS CONTROL OPERATION

5.1 - Start/stop control

The table below summarises the unit control type and stop or go status with regard to the following parameters.

-Operating type: this is selected using the start/stop button on the front of the user interface.

-Remote start/stop contacts: these contacts are used when the unit is in remote operating type (rEM). See sections 3.6.2 and 3.6.3.

-CHIL_S_S: this network command relates to the chiller start/stop when the unit is in CCN control (CCn). Vari- able forced to disable: the unit is halted. Variable forced to Enable: the unit runs in accordance with schedule 1.

-Start/Stop schedule: occupied or unoccupied status of the unit as determined by the chiller start/stop program (Schedule #1). Used when the unit is equipped with an optional CCN/clock board, otherwise the chiller occupied mode is forced to occupied all the time.

-Master control type. This parameter is used when the unit is the master unit in a two chiller lead/lag arrange- ment. The master control type determines whether the unit is to be controlled locally, remotely or through CCN (this parameter is a Service configuration).

-CCN emergency shutdown: if this CCN command is activated, it shuts the unit down whatever the active operating type.

-General alarm: the unit is totally stopped due to failure.

5.2 - Heating/cooling selection

On heat pumps, heating/cooling selection can be controlled differently depending on the active operating type:

•Locally on the unit, using operating types L-C1, L-C2, LC1r and LC2r (for cooling) and L-H (for heating).

•Remotely using the heat/cool selection volt-free contact when the unit is in Remote operating type (rEM).

•Via a CCN command when the unit is in CCN operating type (CCn).

The current heat/cool operating mode on the unit is indicated by item 4 in the Information menu and by the heat/cool LEDs on the summary interface.
