KT-Elektronik SOL3-7

The SOL3-7 is a controller for solar thermal systems, and includes at max nine temperature sensor inputs, seven 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 SOL3-7 provides 117 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

•heating circuit,

•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)
