Notes
1. Used for optional communicating thermostat.
2. Cut JP1 or JP2 for dry contact output on accessory relay 1 and 2.
3. If a single stage thermostat is used place a jumper wire between
Y1 and Y2 at P1 terminal.
4. If disconnect option is not installed connect line power to the L1
and L2 lugs on the compressor contactor.
5. Accessory relays 24VAC max. Activated by compressor output.
6. All 208-230V units are factory wired for 208V operation. If supply
voltage is 230V, installer must rewire transformer.
