Could not wire start and stop on an Altistart 48
All models and serial numbers.
The ATS48 can start with either 2 wire or 3 wire control.
For 2 wire control: Wire a jumper between the STOP and RUN terminals. Close a dry contact between terminals 24V and RUN to start the unit. Open the contact to stop the unit.
For 3 wire control: Wire the normally closed STOP contact between terminals 24V and STOP. Wire the normally open START contact between terminals 24V and RUN. Momentarily closing the START contact will start the unit. Momentarily opening the STOP contact will stop the unit.
