rC01
not equal to 0.
2 Chiller running mode.
3 The recovery key is pushed to enable the function and the recovery led is on.
4 The condensing temperature / pressure is lower than set rC06 –rC07 (differential).
5 The input/output resources are configured
6 The remote recovery digital input is activated.
The recovery function is NOT Enabled if:

FUNCTIONING
Par.
rC01
= 1 unit with two separate circuits:
CIRCUIT # 1
With the recovery function enabled, the unit running in chiller and with the temperature/pressure proper condition, the unit can start the
recovery of the first circuit if the corresponding digital input is active. When the digital input is active the relay of the valve for the
recovery of the first circuit is activated.
CIRCUIT # 2
With the recovery function enabled, the unit running in chiller and with the temperature/pressure proper condition, the unit can start the
recovery of the second circuit if the corresponding digital input is active. When the digital input is active the relay of the valve for the
recovery of the second circuit is activated.
After starting the function, if the digital input becomes not active the recovery function runs for the time set in rC04 before stoppping..
Between the end and the next recovery function the instrument waits the time set in the parameter rC05 even if the digital input is
activated again.
RECOVERY START AND STOP OF THE TWO CIRCUITS CONFIGURED WITH CAPACITY STEPS
During the start and the stop of the fuction the time delay rC02 and rC03 are not counted and the valve is immediately turned on or off.
RECOVERY START OF THE TWO CIRCUITS CONFIGURED WITH MORE THAN ONE CAPACITY STEP
Circuits 1 and 2 configured with more than one step of power (eg each circuit with three compressors), if the thermoregulation requires
to turn on one or more resources and the recovery is activated from the digital input the unit turns on only one step and then waits the
rC02 delay (this delay keep off all the other steps after the recovery is started). After the delay the recovery valve is turned on and, after
the rC03 time (this delay keeps off all the other steps after the recovery is started), the other resources if necessary are turned on.
RECOVERY STOP OF THE TWO CIRCUITS CONFIGURED WITH MORE THAN ONE CAPACITY STEP
Circuits 1 and 2 configured with more than one step of power (eg each circuit with three compressors). After the rC04 time delay
(minimum on time of the recovery function when activated) if the digital input of the recovery is not active the units stops the new
resources for the time set in rC02. After this delay the recovery valve is turned off and the regulation restarts with its normal running
condition.
RECOVERY START OF THE TWO CIRCUITS WITH ALL THE CAPACITY STEPS ACTIVATED
When the system is running with 100% (eg all the three compressor of a circuit are on) of power and the digital input start the recovery
function: before turning on the recovery valve one of the step (depending on the time running hours), is turned off for the time set in
rC02. After rC02 the recovery valve is turned on. Then, after the rC03 time (this delay keeps off all the other steps after the recovery is
started) the resource forced off if necessary is turned on again.
RECOVERY STOP OF THE TWO CIRCUITS WITH ALL THE CAPACITY STEPS ACTIVATED
