Number of wires connected depends on the HVAC system requirement.
•4-wire Heat/Cool System (single stage): RH (jumper between RH and Rc/R), Y1, W1, G
•5-wire Heat/Cool System (single stage): RH, Rc/R (remove jumper between RH and RC/R), Y1, W1 G.
•2-wire Heat only (single stage): RH (jumper between RH and Rc/R), W1
•3-wire Heat only (single stage): RH (jumper between RH and Rc/R), W1, G
•3-wire Cool only (single stage): RH (jumper between RH and Rc/R), Y1, G
