These controls communicate directly with an electronic fan timer (ST9160 Electronic Fan Timer for single stage applications

ST9162 Electronic Fan Timer for two-stage applications) in typical forced warm air furnace applications

It can directly interface with the appropriate power supplies and a system thermostat for additional appliance applications

When controlled directly by a thermostat, these controls do not provide a postpurge function, because power to the control is removed when the thermostat call for heat ends
