Systems

The SOL3-5 provides 72 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 system variants are characterised about a multi-digit system identifier for the choice by basic system components and

extentions The order of the system identifier becomes clear with the help of the followed shown hydraulic systems

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)

Collector pump

A temporarily shown sun above a collector represents an operating state indication

of the pump belonging to the collector

Condition for the activation of the pump is not met and the pump is not operating

Condition for the activation of the pump is met and the pump is operating

The condition for switching off the pump is met, but pump is due to the minimum ON

time still in operation

Condition for switching on the pump is met, but pump is due to the minimum OFF

time yet in operation

Operating mode

The operating modes of heating circuit, hot water circulation and auxilary

heating are in the system scheme, context-sensitive arranged and allow

capture at a glance the current function of the system part
