3.1.9 Contr ller functions

 

The Potterton Solar differential temperature controller

 

contains many functions to regulate and monitor the

 

solar primary system. Including

 

- controller functions for heating the solar cylinder

 

- functions for system protection and system monitoring

 

- additional functions (other accessories may be required

 

 

to achieve these functions).

 

3.1.10 General controlerfunctions

 

 

The controller collects the temperatures of various

 

measuring points and determines the right time to charge

 

the storage tank on account of programmed (additional)

 

functions and controller parameters.

 

 

3.1.11 Cylinder heatingby solar primarysystem

 

Switching action can be adjusted through dTmax (dTon)

 

 

and dTmin (dToff), but dTon cannot be set lower than dT

 

 

off + 1K .The solar cylinder is heated by operating the

 

 

solar pump on output A1 up to the set maximum storage

 

 

temperature. Pump operation is allowed as long as the

 

 

collector panel temperature exceeds the cylinder

 

 

temperature by a set amount.

3.1.12 Systems withtwostoragecylinders

 

 

For systems with more than one storage cylinder (System

 

 

Types 1 and 2) the cylinder heating can be optimised

 

 

depending on the energy supply. Usually the cylinder with

 

 

lower priority will have a lower temperature than that

 

 

with the higher priority. Re-directing the energy to the

 

 

lower priority cylinder will lower the temperature in the

 

 

collector array.To“reinforce” the collector temperature

 

 

the heating of the lower priority cylinder will be

 

 

interrupted for a short while at fixed intervals. If the

 

 

heating criteria for the higher priority cylinder is fulfilled

 

 

then the lower priority cylinder will be heated.

 

 

The higher priority cylinder can be selected in the
