HOLIDAY SCHEDULING (Fig. 21) — The time schedules
may be configured for special operation during holiday pe-
riods. When modifying a time period, an ‘‘H’’ at the end of
the days of the week field signifies that the period is appli-
cable to a holiday. (See Fig. 14.)
The broadcast function must be activated for the holidays
configured on the HOLIDEF screen to work properly. Ac-
cess the BRODEF screen from the EQUIPMENT CON-
FIGURATION table and set the parameter that activates the
BRODEF function to YES. Note that, when the chiller is
connected to a CCN network, only one chiller or CCN de-
vice can be configured to be the broadcast device. The con-
troller that is configured to be the broadcaster is the device
responsible for transmitting holiday, time, and daylight-
savings dates throughout the network.

ferent holidays, perform the following operation:
