The SOL3-5 is a controller for solar thermal systems, and includes at max nine temperature sensor inputs, five 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

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)

Display

System scheme

The controller SOL3-5 it equipped with a graphical display The display

allows it to visualize the current system scheme with all relevant sensor

informations as welll as state informations of pumps and valves for a

quick overview of the operating condition of the system

Among the symbols used in the system scheme are the following:

Element Symbol Meaning

Pump Pump is in operation

Pump is not in operation

Switching valve Switching valve is showen with filled triangles

Valve

Valve is not in operation

Valve 'CLOSE' is in operation

Valve 'OPEN' is in operation

Auxilary heating

Auxilary heating is not in operation

Auxilary heating is in operation

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

Operating mode Symbol Symbol Time phase

Check and set party mode

Using the Party mode function, the controller continues or activates the day

mode during the time when the party timer is active, regardless of the

programmed times-of-use The activation of the party mode (count down) starts

with turning the rotary switch to any operating mode position (e g information

level) When the party timer has elapsed, the party mode timer is reset to 00:00

The party mode counts down in steps of 15 minutes and ranges up to 48 hours
