E2 Parameters Definition:
112 = Highest of Pile 1 or 2
113 = Highest of Pile 1 or 3
114 = Highest of Pile 1 or 4
123 = Highest of Pile 2 or 3
124 = Highest of Pile 2 or 4
134 = Highest of Pile 3 or 4
Any other number will average Pile 1, Pile 2 Pile 3 and Pile 4.
The default setting is 0.
Humid_Diff. This parameter is used when the Humidity Config is set to 1 and
Plenum and Humidity sensors are averaged. If the two sensors drift more than
this setting then the Low Humidity Alarm will be active. The default value is 10
percent.
Max Refrig Fan Speed If running the fan pile differential in Auto, this is the max speed the fans will
ramp up to. The default setting is 100.
Max Pile Diff If the Pile Differential exceeds this value when the Setpoint is in the ramp
condition, the ramp will be halted until the drops below this setting.
Total Heat Hours This is the number of hours the system has run in the heat mode. This value
should be cleared at the start of each storage year.
Total Refrig Hours This is the number of hours the system has run in the refrigeration mode. This
value should be cleared at the start of each storage year.
