Light Load/Peak Load Chiller Configuration

Three different types of light load/peak load chiller behaviour can be selected by parameter LPK-01:

Table 1.   Light load/peak load chiller configuration

LPK-01

Light load/ peak load chiller configuration

0

Light load/peak load control

1

Alternate low and high capacity chillers

2

Keep low capacity chiller enabled


The light load/peak load chiller can be commanded when it is enabled by the input “EnPeakLoadChill“.

If free cooling is commanded, then the light load peak load chiller can only be commanded when parameter LPK-02 is set to 1 (enable light load/peak load chiller during free cooling operation).
