When a water pump works continuosly for CO24 time, the other one is switched on and after CO25 second
the first one is switched off.
If a water pump overload occurs, the water pump is switched off and the other one is switched on.
27. CYCLIC OPERATION OF THE WATER PUMPS
If the water pump is OFF (reached set point), is possible to enable it to run to detect the right water
temperature.
At the end of the ON time, the controller verify if is necessary to switch on the compressor/s or not; if is not
necessary, the water pump is switched OFF for CO85 time and then switched on for another CO87 ON
cycle.
