APC NetworkAIR™ FM-DX 43
D. MASTER CONTROLLER
1. Monitoring and Configuration: The master display shall allow monitoring and
configuration of the precision air conditioning unit through a menu-based control.
Functions include status reporting, setup, and temp/humidity set points. Four LED report
the operational status of the connected Precision air conditioning unit.
2. Controls: The microprocessor shall come equipped with control keys allowing the user to
navigate between menus, to select menu items, and to input alphanumeric information.
3. Alarms: The microprocessor controller shall activate a visible and audible alarm in the
occurrence of any of the following events:
a. High control temperature
b. Low control temperature
c. High control humidity
d. Low control humidity
e. High filter differential pressure
f. Return sensor failure
g. High supply temperature
h. Low supply temperature
i. Loss or low airflow
j. Supply sensor failure
k. Water regulator actuator failure (model specific)
l. PC/Multicool Actuator failure (model specific)
m. High head pressure
n. Low suction pressure
o. Humidifier failure (model specific)
p. Replace canister (model specific)
q. Frequency Controller1 failure
r. Frequency Controller2 failure (model specific)
s. Air block interlock open
t. Water detected (optional)
u. Fire (thermal sensor trip--optional)
v. Smoke detected (model specific)
w. Condensate pump failure
4. Logging: The microprocessor controller shall log and display the 30 most recent alarms.
Each alarm log shall contain time/date stamp as well as operating conditions at the time of
occurrence. Controller shall display the run time hours for major components
(compressors, heaters, humidifier, blower motors).
