695-200 Robertshaw IGNITION CONTROL

The Robertshaw 695 Series electronic blower motor controls were designed for use on heating and cooling equipment. The 695 controls the operation of the induced draft blower and the circulating blower in all thermostat modes. On a call for heat, the induced draft blower is energized. A pressure switch then proves the induction blower is functioning and brings in the gas valve. Operation of the gas valve starts the “on” delay timing. At the end of a pre-selected (and fixed) delay, the circulating blower is energized and it runs continuously until the call for heat is satisfied. At this time the “off” delay (adjustable) is initiated and the circulation blower operates until the “off” delay times out.
