8.6. Parameter
A parameter can have a lower display level than the access level. I.e. not every parameter displayed
can be changed.
8.7. Controller description
8.7.1. Electronic level monitoring
Before switching on the chiller the electronic level monitoring takes effect.
The level is monitored for three states:
 Tank min level STOP; The chiller switches off immediately.

Tank min level warning; The chiller continues running, but does not switch back on if it is at
a standstill. The water feed solenoid valve (only with the automatic water feed option) is
opened.

Tank max level message; The cold water feed/water feed solenoid valve (only with the
automatic water feed option) is closed.
The ideal state is if the level lies above the warning level and below the maximum level. No message
appears in this case.
If the chiller is switched on and the min level warning is reached, the chiller stays switched on so
that a cooling process that has started is not interrupted. If the chiller is switched off, the chiller
does not start, so that a cooling process is not initiated which might not be able to be ended.
8.7.2. Switching the chiller on - off
The selected pump is released if:

it is selected in the system configuration on the software side,
 No fault is queued at the motor protection switch,
 No flow monitoring fault is queued,

No minimum or maximum pump pressure fault is queued.
The following conditions must be fulfilled for the chiller standby status:

The control system has finished its initialisation routine,
 Release of all selected pumps,
 Release of the cold water flow or cold water return sensor,

No exceeding of the cold water flow temperature,
 Release by tank level monitor,
 Release by cold water pressure monitor at evaporator inlet.

Release by other limit values (e.g. conductance)
