control
This mode regulates on both inlet water sensor of the evaporator and the condenser.
This is only applicable on water-cooled chillers.
The same functions are used as in inlet condenser control and inlet evaporator control.
Load-up will be requested when both functions request a load-up and the load-up time = 0. This is an
"AND" function.
Load-down will be requested when one of the functions requests a load-down and the load-down time
= 0. This is an "OR" function.
External thermostat Not accessible because DICN is not possible for condenser-less units and this function is only
available on condenser-less units.
