regulation, is inhibited.
Once the valve is turned on, any additional compressors required by regulation chiller
compressors will be delayed of rC03 seconds after the valve
o
if the heat recovery request comes when the maximum number of available compressor is
switched on, a compressor is switched off and a delay time rC02 starts counting; once
elapsed, the heat recovery valve is activated, condenser fan is switched off (if rC09=1) and
starts conting a delay rC03 after wich the compressor will be re-started (if CO02 time is
elapsed
When the unit enters in recovery operation, the recovery state is maintained for a minimum time set in
parameter rC04.
Exit from heat recovery

if the unit has only one compressor per circuit, when heat recovery request is not active the heat
recovery valve of circuit 1 or circuit 2 is de-activated

if the unit has more than a compressor per circuit:
o
if the heat recovery request is de-activated when the number of compressors switched on is
lower than the maximum available, the recovery valve is activated with delay of rC02
seconds; during this delay the switching on of more compressors of the circuit, if required by
the regulation, is inhibited.
Once the valve is turned on, any additional compressors required by regulation chiller
compressors will be delayed of rC03 seconds after the valve
o
if the heat recovery request is de-activated when the maximum number of available
compressor is switched on, a compressor is switched off and a delay time rC02 starts
counting; once elapsed, the heat recovery valve is activated, condenser fan is switched off
(if rC09=1) and starts conting a delay rC03 after wich the compressor will be re-started (if
CO02 time is elapsed
When the heat recovery is deactivated, the next request will not be fulfilled until the end of time set in the
RC05 (counted from the moment of exit the recovery operation).

43. MASTER / SLAVE FUNCTION

The IC208CX can be used as a slave in a master / slave configuration; the master is represented by a
device that has the specific function, the IPL500 Master.
The use of the device as a slave is enabled automatically when the IC208CX is connected to the Master and
the serial communication with the Master work correctly.
During operation, the slave:
• does not calculate the power to be supplied to the system; the power is calculated by the Master and sent
to the Slave
• operates normally the procedure to enter to the defrost, but before starting the defrost it need the Master
consent
• can be configured to manage compressors type ON / OFF (not inverter, not with capacity step)
• can not be configured to manage the domestic hot water
• can not be configured to handle condensing units
More detailed specifications of Master / Slave operation and configuration are in the IPL500 Master / Slave
documentation.
43.1 DISABLE THE HEAT RECOVERY CYCLE BY CONDENSER TEMPERAURE /
PRESURE
The heat recovery operation can be disabled depending on the condenser condition to avoid a possible high
pressure alarm.
If condenser temperature/pressure is equal or higher than the set rC06 (limit of the recovery cycle), the heat
recovery operation (of the same circuit of the transducer) is disabled.
When the heat recovery is disabled, the bottom display shows b1rC (circuit 1) or b2rC (circuit 2).
