The parameters referred to this function are the following:
- PC64 = Maximum dynamic offset for summer operation (chiller)
- PC65 = Compensation start temperature for dynamic summer set point
- PC66 = Compensation stop temperature for dynamic summer set point
With offsets greater than zero, behaviour is as follows:
The parameters referred to this function are the following:
- PC67 = Maximum dynamic offset for winter operation (heat pump)
- PC68 = Compensation-start temperature for dynamic winter set point
- PC69 = Compensation- stop temperature for dynamic winter set point
6.17.5 Forced shutdown
This function enables the forced shutdown of all compressors, when outlet temperature falls below
the Summer forced-shutdown set point (in the case of chiller operation), or exceeds the Winter
forced-shutdown set point (in the case of heat-pump operation). Compressors can only be restarted
when the temperature crosses the set point once again.
- PC35 = Forced-shutdown enable
- PC36 = Summer forced-shutdown set point
- PC37 = Winter forced-shutdown set point
On MOTOCONDENSING units and with PC11=2, this function is disabled.
