What is the replacement for the Drayton Autotherm?
The Drayton TA/L1 actuator is obsolete, and no like for like actuators are available, this makes the Autotherm controller unusable.
The TA/L1 actuator provides positional feedback to the Autotherm controller, and actuators providing feedback are very few, and providing the correct feedback is not possible.
The Autotherm controller provides considerable functionality, and in our current ranges of controllers, these cannot be matched.

The most appropriate replacement controller is CSC5352. This device will provide a compensated heating system with a timed start, the output relay can be used to enable the hot water system. Please click HERE to upload the data sheet.
If separate time periods are required for the heating system and how water system, then the DC1100/1400 should be considered. Please click HERE to upload the data sheet.
Please note that in both of the above options, new sensors will be required and possibly actuators too.
