Hi to all

i have question about communication wiring between thermostat and the outdoor unit.

Rheem,model-SJKB0120 NL.

and Protech thermostat model Pro-620.

connectors on the thermostat are:
R,O,B,Y1,E,Y2,W2,G,C,L.

connectors on the outdoor unit are:
R,Y1,Y2,B,W3,G,C,A1,A2.

at first is this model of thermostat compatible with this model of package unit?

and if it is,please someone to send me instruction about connecting it right.

The attached file has on page 11 sample layouts which should be of use. ....
