PUMP EVAPORATOR MANAGEMENT

Function
The CLIMATIC™ 60 offers in option a solution to manage a single or double evaporator pump(s).
Description
In case of double pumps, the CLIMATIC™ 60 can manage various possibilities of pumps operating.
Priority to pump 1
The CLIMATIC™ 60 specifi es the priority to pump 1 to start fi rst. Pump 2 is used only as a backup pump and will start only if pump 1
is in alarm. Pump 1 is kept ON as soon as the machine is enabled.
Auto priority to pump 1
Same confi guration as case 1, except that the pump will be stopped in case of dead zone changeover (winter / summer).
Priority to pump 2
The CLIMATIC™ 60 specifi es the priority to pump 2 to start fi rst. Pump 1 is used only as backup pump and will start only if pump 2 is
in alarm. Pump 2 is kept ON as soon as the machine is enabled.
Auto priority to pump 2
Same confi guration as case 3, except that the pump will be stopped in case of dead zone changeover (winter / summer).
No priority
The CLIMATIC™ 60 specifi es automatically the priority of the pump according to the operating hour counter. The fi rst pump to start
will be the one which has the less number of hours of operation. In order to equalize the number of hours the unit is stopped every
tuesday at 02 am to re-specify the priority.
Note: the total operating hour are displayed on the DC60 Advanced on 2 numbers in the menus (2314) and (2315) (pump n°1).
Example:
(2314) = 0123,
(2315) = 4567,
Total Hour = (2314)*10000 + (2315) = 01234567 hours.
No auto priority
Same confi guration as case 5, except that the pump will be stopped in case of dead zone changeover (winter / summer).
