Intelligent temperature control

Basic Functions

The Intelligent temperature controller calculates the flow temperature and the heating circuit pump and the mixer are free. In addition, the buffer nominal temperature is also calculated . The block can be used either for heating or for cooling (adjustable in the Properties window of the block)
 
 
In intelligent temperature control the heating curve takes external influences in to account. (adjustable via the parameter Min , Max , S , N ). For the heating curve: The lower the outside temperature, the higher the flow temperature. Alternatively for the cooling curve: The higher the outside temperature, the lower the flow temperature.
 
By double- clicking on the module or in the Properties window, intelligent room control of the various rooms can be selected. Thus, the intelligent temperature control can see the desired room temperature and the room temperature deviations.

Inputs

 

AI

Analog Input outside temperature

For providing outside temperature

Ib

Boost input

When heating : Maximum flow temperature (parameter max) is output at AQF

When cooling : Minimum flow temperature ( parameter Min ) is output at AQF

St STOP input

Digital input - Suspends manifold operation. When on:

During heating: The minimum target flow temperature is put out on AQf and AQb

During cooling: The maximum target flow temperature is put out on AQf and AQb

Parameter

Min

Minimum flow temperature

 

Max

Maximum flow temperature

 

B

Buffer Temperature

Buffer temperature increase (for heating) or Buffer temperature lowering (during cooling )

S

Slope of the heating or cooling curve

 

N

Curve offset or cooling curve

During heating the flow temperature is increased by this value , lowered during cooling.

Str

Parametre - Start threshold in %

Only when the valve of at least one room is indicating a greater demand than this output Qp to indicate a manifold demand is switched on

G

Gain of roomtemperature difference

Sets with what gain the room temperature difference is weighted (default value = 1)

I

Room target temperature increase during the heating phase

 

 

Outputs

 

AQt

 

Room target temperature of the room with the highest (heating) or the lowest (when in cooling) required target flow temperature

TxQr

Text output

Provides the name of the room with the highest (when heating) and lowest (when cooling) target flow temperature

AQf

Flow Target Temperature

 

AQb

Buffer Target Temperature

 

Qp

Digital output

Output  to indicate manifold demand for mixing valve or pump control

AQr

Heating / Cooling unit requirement in °CM2

Heating a cooling demand of each room is calculated as: Temperature difference * Room size

AQI

Heating / Cooling load (0-100%)

The heating and cooling load of each room is calculated as follows: demand of room * area of room / total area

AQi

Flow temperature increase / decrease

Current increase of flow temperature (during heating) or Current decrease of flow temperature (during cooling)

Qe

Digital error output
