R-G contacts close on the comfort control sending 24VAC to G of the AFC. 3. The AFC communicates to the EHC that st stage electric heat is being called upon. 4. The EHC determines the number of elements that are used for st stage and sends a message to the AFC for that correct cfm. (The EHC determines the amount of heat per stage by either factory programming or by the kw jumper position) 5. The AFC micro-processor sends a command to the serial communicating blower motor to run and close the blower interlock relay on the EHC. The blower motor will now run at the W electric heat cfm. 6. On subsequent calls for W2 and/or W3, the EHC will communicate to the AFC the required airflow request and energize the additional relays. NOTE: The EHC has lead-lag logic built in that energizes the electric heat relays based upon cycle counts. For example: BAYEV**5 The first time W only is energized; the K relay would close and energize the A heater. The second time W only is energized; the K2 relay would close and energize the B heater. The third time W only is energized; the K3 relay would close and energize the C heater. Defrost. The OD unit will initiate defrost and send 24VAC to the O terminal of the AFC. 2. The AFC will communicate to the EVC that the OD is in defrost and the EVC will start to maintain the correct superheat. 3. X2 from the OD will send 24VAC to W of the AFC. 4. The AFC communicates to the EHC that st stage electric heat is being called upon. 5. The EHC determines the number of elements that are used for st stage and sends a message to the AFC for that correct cfm. Optional Condensate Switch. An optional OEM condensate switch can be installed within the unit. This switch is only available through the National Distribution Center or Global Parts. 2. Switch contacts are normally open and close when water level rises. The closed switch will interrupt current flow to the YO terminal and de-energize the OD unit. 3. Switch is only operational during cooling mode. Condensate overflow is not operational during heating or defrost modes. Standard aftermarket condensate switches cannot be used within the unit but can be installed exterior of the unit. Switch should be wired in series with YO wiring to the OD unit. Freeze Protection. The EVC control has the ability to sense when the coil is beginning to ice. When this event occurs, the contacts to the YO circuit will open and de-energize the OD unit. 2. The indoor blower motor will continue to run to aid in defrosting the coil. After 20 minutes, the YO contacts will close and cooling operation will begin again. Blower Delays. Blower delays can be set to enhance system efficiency. See S2 dip switch settings table. TAM7 5
