The Power LED #5 (RED) on UC1 or any LED's on UC1 or MAC1E should not be on. Test the safety circuit by removing either lead from Fan Prover switch connected to UC1 P1 and P2 Fan Prover safety circuit. Do not let the opened LEAD touch a ground or damage may occur to the control when power is reestablished. Reestablish power to the UC1 and interlocked appliances and initiate a call for heat.
