Issue

DC2000 series Optimiser / Compensator Controller requires replacement due to obsolescence.

Product Line

Field Devices

Environment

DC2000 series Optimiser / Compensator Controller installed to control Variable Temperature Mixing Valve, Boiler/s, Pumps etc.

Cause

Obsolescence of DC2000 series Optimiser / Compensator Controller.

Resolution

OVERVIEW

DC2000 series Optimiser / Compensator Controllers are flexible with regard to the number and type of electrical inputs and outputs to which they may be connected, enabling the Controller to be applied to a wide range of control applications. 

Overview details of the DC2000 Optimiser / Compensator Controller may be viewed here.   

INSTALLATION AND COMMISSIONING

In view of the numerous control applications to which the DC2000 series Optimiser / Compensator Controller may be applied, numerous wiring connection variations will also apply.

Please therefore check the number of inputs and outputs connected to the DC2000 series Optimiser / Compensator Controller installed before proceeding, as this will assist in determining the suitability of the possible replacement Controller suggested below.

Installation and Commissioning details of the DC2000 series Optimiser / Compensator Controller may be viewed here.

POSSIBLE REPLACEMENT

The most common control application to which theDC2000 series Optimiser / Compensator Controller may be applied comprises the following combination of inputs and outputs. 

Outside Air Temperature Sensor

Inside Air Temperature Sensor

Compensated Heating Temperature Sensor

Variable Temperature Heating Circuit Valve Actuator

Boiler/s (2 maximum)

H W S On/Off output (independent)

Should such inputs and outputs be confirmed then the DC1100 Optimiser / Compensator may be installed in place of the DC2000 series Optimiser / Compensator Controller.

Details of the DC1100 Optimiser / Compensator Controller may be viewed here.

Drayton A7xx series Sensors connected to the DC2000 Optimiser / Compensator Controller are compatible with the DC1100 Optimiser / Compensator Controller and may therefore be retained.

N.B.

It should be noted that where a DC2000 series Optimiser / Compensator Controller is included in an installation of a more complex nature then an alternative solution utilizing different products may need to be considered.

In such installations not only will the DC2000 series Optimiser / Compensator Controller need to be replaced but its associated Sensors will also need to be replaced.

Resolutions to such installations may best be determined following a review of the control system installed by a member of the local Schneider Electric office.
