NOTES:
1. 48/50TJ004-007 units only have one stage of cooling, but can have 2
stages of heat. In these applications set DIP switch B to ON for 2-STAGE
operation.
2. For 50HJQ and 50TJQ heat pump applications, set switch A to OFF (air
conditioning). The 50HJQ and 50TJQ units do not have an ‘‘O’’ terminal.
