Chapter 4: E2 Controller
Figure 4-24. Control menu loop.
4.5.4 Control Menu Loop
From the Control Menu, you may select from four screen menus: Setpoints,
Alarm Setpoints, Clock, and Version. The controller may be programmed by
the user to require Level 1 password authorization to enter this menu loop
(see Section 4.2.6). Once password access is granted, you may select and
adjust the setpoints controlling the performance of the unit, enable alarms
and determine their setpoints, and set the clock.
The Setpoints (SET) screens allow you to view and adjust the temperature
and humidity setpoint control parameters and compare them to system level
operating data derived from the various sensor/transmitter inputs. See
Section 4.5.4.1.
The Alarm Setpoints (ALARM SET) screens allow you to enable and adjust
the high and low temperature and humidity alarm setpoints and offsets, and
compare them to the control setpoints and to the system level operating
data derived from the sensor/transmitter inputs. See Section 4.5.4.2.
From the Clock screens you may view and adjust the current time, date and
day, and set up operating schedule(s) and setpoints for the A/C
system. See Section 4.5.4.3.
Two Version screens are provided for information only. They show
controller hardware and software details that are useful to Black Box
Technical Support if you need help.
