    The blower cycles with demand from “C1” on logic panel. Mechanical cooling is used to satisfy the demand. If cooling lockout is chosen, the equipment is shut down and the outdoor air dampers are held closed. The degree of heating setback or cooling setup is determined by separate resistors at the…
