For this function it is necessary to connect a condenser valve end-switch or a condenser flow switch. When the chiller condenser valve is commanded on and the condenser status is off within the delay defined by ALM-01, then a condenser valve alarm is generated. The chiller unavailable flag (chiller common alarm output) and the chiller shutdown sequence is started.
The condenser valve alarm is displayed by DISP-01.
The alarm must be reset (manually or automatically) in order to start-up the chiller again.
