Switching on order or priority:
Governs the order in which available sources are switched on. The switching off order is the opposite of the switching on order.
Some sources may not be available due to being out of the operating temperature range (see section 6.3), due to have an alarm
signal in their digital input (see sections 0 and 8.1) or due to the temperature sensor of the source being faulty or disconnected (see
section 8.1). Sources that are available will follow the order or priority shown in table 6.1.
For example, if sources 1, 3 and 4 are available, the system will start up with source 1. Then, if necessary, it will start source 3 and if
it detects that one more is necessary, it will start source 4. When the e-source determines that it should switch off a source, the
first will be source 4, then, if necessary, it will switch off source 3. If the system shuts down completely it will also switch off source
1.
For this reason, the source that is intended to operate for the longest time should be connected and configured as "Source 1", the
next as "Source 2", and so on.
6.3. Configuration of each source
Main brine pump control
1. Used to enable or disable use of the main brine pump.
2. Used to configure the maximum and minimum speed at which the pump can work.

Source 1, 2, 3 and 4
1. Used to enable the source.
2. Used to configure the source as geothermal or aerothermal.
Max/min source 1, 2, 3 and 4
1. Used to configure the maximum and minimum outdoor temperature at which each
source is allowed to function.
2. Used to configure the maximum and minimum glycol temperature at which each
source is allowed to function.
