Plant Extension timer

The TP/EXT1 plant extension timer is designed to extend the normal period of run time of a system for a selected time up to 6 hours. The plant extension timer operates a set of normally open volt free contacts and is available for 24VAC or 240VAC operation.

The LEDS indicate the hours set/remaining for the extended period of operation. The TP/EXT1 incorporates a remote start facility which allows the extension timer to be set at any time but will not run until a start signal is received. A useful application of this is to automatically initiate the extension timer when the system switches off at the end of a normal period of operation.
