SECTION 5 – SEQUENCE OF OPERATION
SMOKE PURGE
• The Series 100 units have three specialized smoke
purge sequences.
• These three sequences are outside the normal op-
erating sequences of the unit.
• They are typically only used in very specic ap-
plications, such as after a re or smoke event.
• Smoke purge sequences can be initiated either by
a hardwired input to CTB1 or through a command
from the BAS.
• When the unit enters a Smoke Purge mode, all cool-
ing and heating functions is immediately stopped.
Smoke Purge Setup
• Three different smoke purge sequences can be set:
1. Smoke Purge 1
2. Smoke Purge 2
3. Smoke Purge 3
• Each of these different sequences can be set for
one of three options:
1. Purge
2. Pressurization
3. Evacuation
• The different options for each sequence must be
selected in the PROGRAM-UNIT DATA menu.
