Pump OL
Pump Motor Overload
Pump overload input trips. The input transitioning to OFF is considered
an operation.
Alarm
Alarm Output
Alarm output actuations. The alarm output transitioning to ON is
considered an operation.
High Temp
High Temperature Input
High temperature input trips. The input transitioning to OFF is
considered an operation.

Cooling
Water
Cooling Water
Temperature
The cooling water temperature as measured at the end of the valve vent
during normal TCU startup. Value is saved through power cycles and is
overwritten at startup during the venting sequence.
Cooling LTS-
%
Cooling Long Term
Average Percent
Displays the average used cooling capacity after the unit reached
setpoint. This value resets if power is cycled or the setpoint is changed.
Heating
LTA-%
Heating Long Term
Average Percent
Displays the average used heating capacity after the unit reached
setpoint. This value resets if power is cycled or the setpoint is changed.

Lst Alm Dur-
s
Last Alarm Duration in
Seconds
How long the machine was in an alarm state. It counts from the initiation
of an alarm to the remedying of the condition or manual reset of the
alarm (for non-auto-resetting alarms).
Low Pres-hrs
Low Pressure Hours
The number of hours the machine was in a running mode but the pump
was turned off due to insufficient pressure to the unit.
10/18
Mem @-
x10000
Memory Writes
The number of times the memory has been written to. Shown in units of
x10000.
Loop Time-
ms
PLC Loop Time
How long it takes the controller to run the entire program and loop back
around to begin again. PID loop is updated only once per second
regardless of this value.
Max Lp
Time-ms
Max PLC Loop Time
The maximum recorded controller loop time once the controller had
loaded all initial parameters.
PS Volts-V
Power Supply Voltage
Incoming power supply voltage.
OS Freq-Hz
Power Supply Frequency
Incoming power supply frequency for AC supply. In the case of a DC
supply, this is shown as "0".
