Product description

You have decided on a solar thermal system in order
to use solar energy, save the environment and fossil
fuels.
The DeltaSol AL E solar controller is the brain of
®
your solar thermal system. It makes sure your system
runs efficiently and with optimum energy yield.
The DeltaSol AL E is equipped with a compre-
®
hensive display and a RESOL VBus
®
remote diplays can be connected. Due to the energy-
efficient switch-mode power supply, power consump-
tion is very low.
This manual gives you an overview of your control-
ler and shows how to read measurement and balance
values.

Data communication / Bus

The controller is equipped with the RESOL VBus
data transfer with and energy supply to external mod-
ules. Carry out the connection at the two terminals
marked "VBus" (any polarity). One or more RESOL
VBus ® modules can be connected via this data bus,
such as:
• RESOL GA3 Large Display from version 1.31
• RESOL SD3 Smart Display from version 1.31
• RESOL DL2 Datalogger
• RESOL VBus
• RESOL AM1 Alarm module
