APPENDIX C — CCN TABLES (cont)
CONFIGURATION TABLES (cont)
*Not supported.
†Only condenser pump sequence 1 is supported.
NOTES:
1. Flow checked if pump off needed when a command is sent to the primary
pump to prevent cooler from freezing in winter conditions. Command will
set the cooler flow switch to closed while the controls stop the cooler
pump. The controls may then generate an alarm. If this decision is active,
the cooler flow switch is not checked when the cooler pump is stopped.
2. If cooling reset select set point has been selected the set point based on
4-20mA input signal through ComfortLink™ control, then a 4-20 mA reset
function shall be ignored. Configuration 3 (4-20mA Control) and 4 (Space
Temperature) shall require an Energy Management Module.
3. Configuration 2 (4-20mA Control) shall require an Energy Management
Module. Configuration 1 Switch Demand limit provides 3 step demand limit
if an Energy Management Module is present. Otherwise, only one step is
allowed.
4. Reverse Alarms Relay configuration will be deenergized when an alarm
and alert relay is present and will be energized when no alarm is present.
