Replacement of Satchwell CD2201 Compensator Controller–Actuator by Schneider Electric Satchwell CSC Compensator Controller due to obsolescence.

[Product_Support]

Issue

Satchwell CD2201 Compensator Controller–Actuator requires replacement.

Environment

Stand alone discreet Satchwell CD2201 Compensator Controller–Actuator

Cause

Obsolescence of Satchwell CD2201 Compensator Controller–Actuator

Resolution

Replace Satchwell CD2201 Compensator Controller–Actuator with Schneider Electric Satchwell CSC Compensator Controller, compatible Temperature Sensors and MD Series Actuator and Linkage Kit.

1. Replace Satchwell CD2201 Compensator Controller–Actuator with Schneider Electric Satchwell CSC Compensator Controller.
   N.B.
   Two models of the Schneider Electric Satchwell CSC Compensator Controller are available :-
   CSC 5252 Compensator Controller without Time Clock
   CSC 5352 Compensator Controller with integral Time Clock 
   Details of the Schneider Electric Satchwell CSC Compensator Controllers may be viewed here.
   It should be noted however that the CD2201 Compensator Controller–Actuator had no integral Time Clock.
2. Replacement of Air Temperature Sensors
   It should be noted that the existing Satchwell Outside Air Temperature Sensor associated with the CD2201 Compensator Controller–Actuator is obsolete and should be replaced.
   Similarly, it should be noted that the existing Satchwell Inside Air Temperature Sensor associated with the CD2201 Compensator Controller–Actuator is obsolete and should be replaced.
   Details of replacement Schneider Electric STO600 Outside Air Temperature Sensor may be viewed here.
   Details of replacement Schneider Electric STR600 series Inside Air Temperature Sensor may be viewed here.
   N.B.
   It should be noted that the CSC Compensator Controller will perform entirely satisfactorily without the connection of an Inside Air Temperature Sensor.
3. Replacement of Water Temperature Sensor.
   It should be noted that the existing integral Satchwell Water Temperature Sensor associated with the CD2201 Compensator Controller – Actuator cannot be re-used and should therefore be replaced.
   In order to minimise mechanical work it is suggested that a Surface Mounting Temperature Sensor is installed on the pipework, rather than an Immersion Temperature Sensor installed in a Pocket in the pipework.
   Details of replacement Schneider Electric STC600 Surface Temperature Sensor may be viewed here.
4. Replacement of Actuator.
   Whilst the existing Satchwell MB Valve Body may be retained, a new Schneider Electric Actuator and Linkage Kit will need to be installed on the MB Valve Body in order to permit control from the CSC Compensator Controller.

   Details of the Schneider Electric LMD/AR-MB Linkage Kit may be viewed here.

Please be aware: since July 2016 the CSC compensator and other descrete controllers were withdrawn from service.
