"
- CZ": R4 and T5 enable a charging zone control to be created for charging in 2
thermal layers. A detailed functional description of this add-on can be found on page 15.

"Basic - R" diagram: In some cases the solar circuit pump must be controlled according to the
solar radiation. For this reason, a S7 radiation sensor must be installed in the collector level. For
control purposes T1 must be inserted between the collector and bypass. A detailed functional
description of this add-on can be found on page 15.
To prevent erroneous settings, the described switch-on and switch-off values are interlocked,
this means they can be set only at a specific value to one other.
Since with this diagram, speed controls are only useful when the objective is "absolute
temperature", this control objective has been saved both in the settings "Absolute temp." and
also "Differential temp.". The control devices are therefore dependent on this setting.
