Honeywell Controller Features

• The S8610U controller provides many safety functions for controlling a gas-powered heater. The controller's circuitry monitors the pilot's flame during heating operations, making sure that the flame height is not too small or large. In addition, the controller activates the heating system's ignition sequence based on communications with the thermostat. Also, the gas supply will automatically shut off if the controller detects no flame from the furnace or boiler.
