NOTES:
1. Flow checked if pump off needed when a command is sent to the
primary pump to prevent cooler from freezing in winter condi-
tions. 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 to 20 mA input signal through
Comfort
Link™
controls, then a 4 to 20 mA reset function shall be ignored. Con-
figuration 3 (4-20mA Control) and 4 (Space Temperature) shall
require an Energy Management Module.
3. Configuration 2 (4-20mA Control) shall require an Energy Man-
agement Module. Configuration 1 Switch Demand limit provides
3 step demand limit if an Energy Management Module is present.
Otherwise, only one step is allowed.
