Description
Noise
Reduction
Unit is running with the Quiet Mode activated. Active setpoint may differ from what
has been set as cooling setpoint.
Max Pulldn
Unit thermostat control is limiting the unit capacity because the water temperature
is dropping at a rate that could exceed the active setpoint.
Pumpdn
Unit is shutting down.
4.2.3 Circuits Enable
As for the unit enable, the circuits can start only if all the enable setpoints/signals are active:
• Circuit Switch Enable (signal) = Enable
• Keypad Enable (setpoint) = Enable

4.2.4 Circuit Status
One of the texts strings listed in the table below will inform, on the HMI, about the Circuit Status.
Overall Status
Status
Description
Off:
Ready
Circuit is off waiting for a stage up signal from thermostat control.
Stage Up Delay
Circuit is off waiting for the stage up delay to expire.
Cycle Timer
Circuit is off waiting for the compressor cycle timer to expire.
BAS Disable
Circuit is off by BAS signal. Check with the BAS company how to start the unit.
Keypad
Disable
Circuit is off by the local or remote HMI. Check with your local maintenance if it
can be enabled.
Circuit
Switch
Circuit is off by Enable switch. Turn the Enable switch to 1 to allow the circuit start
up procedure to start.
Oil Heating
Circuit is off because the oil temperature is too low to guarantee a proper
lubrication of compressor. Heating resistor is activated to eliminate this temporary
condition. It’s suggested to power up the unit in advance to avoid this limiting
condition.
Alarm
A circuit alarm is active. Check the alarm list to see what is the active alarm
inhibiting the circuit to start and check if the alarm can be cleared. Refer to section
5.before proceeding.
Test Mode
Circuit mode set to Test. This mode is activated to check operability of onboard
circuit actuators and sensors. Check with the local maintenance if the Mode can
be reverted to Enable.
Max Comp
Starts
Compressor starts exceed the maximum number of starts per hour.
VFD Heating
Inverter on compressor cannot start because of low internal temperature. Heating
resistor is activated to eliminate this temporary condition. It’s suggested to power
up the unit in advance to avoid this limiting condition.
Maintenance
A component needs to be replaced or maintained. Refer to section 5.before
proceeding.
EXV
Preopen
EXV prepositioning before compressor starts.
Run:
Pumpdown
Circuit is shutting down because of thermostat control or pumpdown alarm or
because the enable switch has been turned to off.
Normal
Circuit is running within the expected operational conditions.
Disch SH Low
Discharge superheat is below the acceptable value. This is a temporary condition
that should disappear after few minutes of operation.
Evap Press Low
Circuit is running with low evaporator pressure. This could be due to a transitory
condition or a lack of refrigerant. Check with the local maintenance if corrective
actions are required. Circuit is protected by preventive logic.
Cond Press
High
Circuit is running with high condenser pressure. This could be due to a transitory
condition or high ambient temperature or problems with the condenser fans.
Check with the local maintenance if corrective actions are required. Circuit will be
protected by preventive logic.
High LWT Limit
Circuit is running with a high water temperature. This is a temporary condition that
will limit the maximum compressor capacity. Reduction of the water temperature
will allow the compressor to reach the full capacity.
High VFD Amps
Inverter current is higher than the maximum allowed current. Preventive logic will
protect the inverter.
