The Setpoint display normally shows the set point temperature. A decimal point in the lower right corner of this display
indicates the temperature unit of measure is set to °F, no decimal point indicates the temperature unit of measure is set to °C.
See the Program Menu section to change the temperature scale units of measure. This display also shows alarm codes and
programming information.
Actual The Actual Temperature display normally shows supply temperature. A decimal point in the lower right corner of the display
indicates the temperature displayed is the supply temperature, no decimal point indicates the temperature displayed is the
return temperature. To change the display from supply to return temperature, press and release the Display/Program button.
The display will return to the default Supply temperature automatically after 5 seconds without a button press. This display also

Display Description of Operation
Control Power
The Control Power light is on and green when 24VDC control voltage is present.
Autostart Signal The Autostart Signal light is green when closed (run), yellow when open (stop), and unlit if this feature is disabled. This feature
allows starting and stopping of the unit by a remote contact closure. From the factory, the Autostart feature is disabled. See the
Program Menu section for instructions on how to enable or disable the Autostart feature. Do not introduce any external voltage
to the Autostart contacts; this will result in damage to the controller.
Pump
The Pump light is solid green when the pump is running and flashes red if the pump motor overload trips.
Heat
The Heat light is on and green when the heating is required.
Cool
The Cool light is on and green while in normal running operation when the cooling valve is open. The light flashes green during
an Autovent sequence or Process cool-down sequence.
Coolant Pressure
The Coolant Pressure In light will flash red if the inlet cooling water pressure drops below the set point of the low-pressure
safety switch. If a low-pressure condition occurs, the unit will automatically stop and remain de-energized until the cooling
water pressure is above the cut-in set point of the pressure switch. The light is solid green if the Coolant Inlet Pressure is satis-
factory. It will flash green while in the Purge mode.
Temperature The Temperature Limit light flashes yellow if a high or low temperature limit warning occurs and flashes red if a high or low
Limit
temperature limit safety occurs. A temperature limit safety stops the unit. Pushing the Alarm Reset button will reset this alarm.
Electrical Phase The Electrical Phase Error light flashes red when a line voltage problem exists. This error indicates a loss of phase, phase
Error (Optional)
1 reversal, or phase imbalance.
Heat Error The Heat Error light is solid red when the controller calls for heat and heating does not occur. The Heat Error light flashes red
1
(Optional) when the controller does not call for heat but heating occurs. Both conditions cause the unit to stop.

Down (Optional)
1 lights will also flash green during a seal saver sequence. After the Process Cool Down sequence is complete, the unit stops
and the Process Cool Down light remains green to indicate the completion of the sequence. See the Process Cool Down But-
ton section for a description of the Process Cool Down function and operation.
