Setting date
3
Setting the time interval when the pump can turn on to take the
heat energy to the solar collector on Holiday mode.
This
interval must be in the night, for this mode to make sense!
4
Setting time intervals which allow the electrical heater to turn
on (Setting timer)
5
Setting start of the daily and night electricity rates. An important
information for correct reporting the consumed electricity.
6
Setting the differential temperatures between the solar collector
and the water heater for turning the pump on or off. For a
temperature difference between the collector and the water
heater more than
Pump On
, the pump will turn on and will
work until the difference gets less than
Pump Off.
7
Setting the differential temperatures between the boiler (the
second heat source) and the water heater for turning the pump
on or off. For a temperature difference between them more than
Pump On
, the pump will turn on and will work until the
difference gets less than
Pump Off.
8
Setting temperature for protecting the collector from freezing
and a critical minimum temperature. If the collector's
temperature is the same as in Pump On, the pump turns on to
take heat from the water heater to the collector.
