[. . . ] LED #2 (Blue) shows that the burner is approved to fire after the Venter Fan Prover safety circuit through the UC1 is completed. MILLIVOLT INSTALLATIONS Each millivolt appliance interlocked with the MAC1E must have its own WHKE kit installed. The WHKE Gas Pressure Switch actuates the Venter through the A - B Dry contacts. [. . . ] MAC1E SAFETY INTERLOCK TEST PERFORM THE FOLLOWING INTERLOCK TEST AFTER CONNECTING MAC1E TO UC1 AND INTERLOCKING ALL BURNERS 1. MAC1E LED #1 (AMBER) should be on indicating an appliance call for heat. If the UC1, P1 & P2 Prover safety circuit is closed, indicating an approved condition, the appliance interlock relay will close making terminal #3 closed to terminal #4. The Power LED (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. After 60 seconds a Prover Start Up fault should arise with UC1 LED #4 flashing 3 times. Remove appliance call for heat and power to the UC1 and any interlocked appliances. The Power LED (RED) on UC1 or any LED's on UC1 or MAC1E should not be on. Reestablish power to UC1 and interlocked appliances and initiate a call for heat from each appliance to confirm proper operation of UC1, MAC1E and appliances. Perform Draft Adjustment and Combustion air safety check as outlined in Venter/Inducer installation manual. IMPORTANT: DO NOT OPERATE AN APPLIANCE THAT OPERATES WITH THE PROVER SAFETY CIRCUIT DISCONNECTED!RESETTING FAULT CODE CREATED BY STEP 4 OF SAFETY INTERLOCK TEST IMPORTANT: Prior to accessing the fault code memory, note the settings of the UC1 dip switches so that they can be returned to their original Pre / Post-Purge positions. When power is supplied to the UC1 use caution when moving dip switches. The last fault code can be retrieved at any time by setting all dip switches 1-8 to the up, or "on" position. The last fault code, or lack there of, will be indicated by counting the number of times LED 4 flashes.
