Chapter 4: E2 Controller
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.
