Test Mode
Unit mode set to Test. This mode is activated to check operability of onboard
actuators and sensors. Check with the local maintenance if the Mode can be
reverted to the one compatible with unit application (View/Set Unit – Set-Up –
Available Modes).
Auto
Unit is in Auto control. The pump is running and at least one compressor is
running.
Auto:
Noise Reduction
Unit is running with the Quiet Mode activated. Active setpoint may differ from
what has been set as cooling setpoint.
Wait For Load
Unit is in standby because the thermostat control satisfied the active setpoint.
Evap Recirc
Unit is running the evaporator pump to equalize the water temperature in the
evaporator.
Wait For Flow
Unit pump is running but the flow signal still indicate a lack of flow through the
evaporator.
Pumpdn
Unit is shutting down.
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.
Unit Cap Limit
Demand limit has been hit. Unit capacity will not further increase.
Current Limit
Maximum current has been hit. Unit capacity will not further increase.
As soon as the unit status turns to Auto, the start sequence is initiated. The start sequence follows
the steps indicated in the simplified flowchart:
5.2.2 Preparing circuits to start
To allow a circuit start up is required to enable the circuit using the enable switch located on the
unit switchbox. Each circuit is equipped with a dedicated switch identified with Q1, Q2 (if available)
or Q3 (if available). The enable position is indicated with a 1 on the label whereas the 0 position
corresponds to disable.
The status of the circuit is indicated in the View/Set Circuit – Circuit #x – Status/Settings. The
possible status will be described in the following table.
