Ramp loading select. For units with more than one compressor per circuit.

 

 

 

 

Yes = ramp enabled

 

 

 

 

No = ramp disabled

 

 

 

 

This configuration enables the ramp to be activated for heating or cooling (depending on configuration): the

 

 

 

 

maximum rate (in °C/min) of temperature drop or rise for the heat exchanger water (leaving or entering, upon

 

 

 

 

configuration). Ramp setting value can be configured in the Setpoint menu.

Delay at start-up. This value is reinitialised after power-up or when both circuits are halted by local, remote

 

 

 

 

or CCN command. No compressor will be started up until this pause has expired. However, the evaporator

 

 

 

 

pump command will be activated immediately. The safety lockout loop will not be checked until the pause has

 

 

 

 

expired.

If the auto sequence is selected, the pump change-over occurs when the rotation delay is elapsed. If the

 

 

 

 

manual sequence is selected then, the selected pump is used in priority. Change-over occurs if one pump

 

 

 

 

fails.

Pump changeover delay. Displayed if auto pump sequence is selected. This parameter is used for pump

 

 

 

 

auto-rotation: the control tries to limit the pump run time difference to the pump changeover delay value.

 

 

 

 

Change-over between pumps occurs when this difference becomes greater than the configured pump

 

 

 

 

changeover delay.
