Quick installation and operating manual KT-Elektronik
The SOL3-3 is a controller for solar thermal systems, and includes at max nine temperature sensor inputs, three switching
outputs, one pulse input and one 0-10V input or output
The controller is ready to use with the temperatures and operating schedules preset by the manufacturer On start-up, the
current time and date need to be set at the controller
This Quick manual contains necessary information for installation and start up

Systems
The SOL3-3 provides 26 different hydraulic systems These differs in basic system components and extentions
Basic system components Extentions
•number of collector arrays,
•number of storage tanks,
•switching between collector arrays and storage tanks using
valves or pumps,
•internal (or non) or external heat exchanger
•auxilary heater,
•circulation pump
The schemes below are only schemes, without any kind of basic valves and security equipement A system scheme is
identified by a explicit system schema indicator (e g I o 2. I.0)
System I  I.0.0
1 collector array, 1 storage tank
System 2  I.0.0
2 collector arrays (valve),
1 storage tank
System 3  I.0.0
2 collector arrays (2 pumps),
1 storage tank

Every shown schemes above could be extend with some additional functions The extentions (e g heating circuit, auxilary
heating and circutation) can be combined They are coded in the lower digits of the system schema indicator
Xxx.0.0 no extention
xxx. I.0 auxilary heating
xxx.2.0 circulation pump
xxx.3.0 auxilary heating and circulation pump
Example extentions of the basic system scheme I - I
System I – I. I.0
(with auxilary heating)
1 collector array, 1 storage tank,
System I - I.2.0
(with circulation)
1 collector array, 1 storage tank
System I - I. 3.0
