If the quantity of milk is increasing without pre cooling the milk with mains water, the selector switch can be
set to +50%.
Do not forget to switch back to -50% when milk production reduces.
TR15
If a time relay (TR15) is installed, the cooling unit is started with a delay. This means if milk cooling (ice-
water pump) is started, the time relay is counting down and after the preset time and if not enough ice is
available, the cooling unit starts forming ice.
Time switch
A time switch can be mounted in areas where electricity cost is lower during certain periods in time. This
time clock controls the cooling unit to build ice in periods of low electricity cost.
