Description of the solar thermal system and the solar functions

Description of the solar thermal system
Additional solar systems can be created by adding functions to
a solar thermal system. You will find examples of possible solar
systems in the connection diagrams.
Solar thermal system (1)

Description of the solar functions
Adding functions to the solar thermal system forms the
required solar system. Not all functions can be combined.

Solar thermal system for solar DHW heating ( Fig. 17, page 199)
• If the collector temperature exceeds the temperature at the bottom of
the cylinder by the set switch-on temperature differential, the solar
pump is switched on.
• Control of the flow rate (Match-Flow) in the solar circuit via a solar
pump with PWM or 0-10 V interface (adjustable)
• Monitoring of the temperature in the collector array and in the

cylinder
External heat exchanger for solar system at cylinder 1 ( Fig. 18,
page 200)
• If the temperature at the heat exchanger exceeds the temperature at
the bottom of cylinder 1 by the set switch-on temperature
differential, the cylinder primary pump is switched on. The frost
protection function for the heat exchanger is ensured.

Transfer system with solar-heated pre-heating cylinder for DHW heating
( Fig. 19, page 201)
• If the temperature of the pre-heating cylinder (cylinder 1 - left)
exceeds the temperature of the standby cylinder (cylinder 3 - right)
by the set switch-on temperature differential, the transfer pump is
switched on.
