Description
Robertshaw 790-400 Ram-4 Ignition Module Control
The RAM intermittent ignition controls are 24 and 120 VAC. When the thermostat calls for heat, RAM’s IID Control simultaneously initiates ignition sparking and opens the pilot valve portion of the gas valve. Pilot flame recognition stops ignition sparking and opens the main valve portion of the gas valve. Pilot burner flame is continuously monitored at a synchronous frequency for the duration of the heating cycle. Should the pilot flame fail during the heating cycle, the control will shut off the main valve until the pilot flame is established.
