Choose the correct operating mode Sensor setup Available modes How it works No external temperature sensor Power and ventilation The heater runs continuously at the selected power. Ventilation circulates air without heating. External temperature sensor connected Temperature, heat plus ventilation, and ventilation The controller can regulate around a temperature setpoint. Heat plus ventilation stops combustion above the setpoint, circulates air, then restarts heating when the temperature falls. Temperature and heat-plus-ventilation modes require a compatible external temperature sensor, AUTOTERM assembly 1458 or AT4-0017-AA0, sold separately. Power mode does not require the external sensor. AUTOTERM Air heaters manufactured on or before 16 November 2016 do not support ventilation mode. Check the heater production date on its warranty card before ordering for an older installation. Controls and indicators Rotary knob adjusts fan speed, heating power or desired temperature, depending on the selected mode and sensor setup Dedicated heater on/off and ventilation buttons LED indicators show heating, purge, ventilation and fault states Red LED blink codes provide basic fault information Allow the heater to complete its shutdown purge. Do not disconnect the control panel or cut heater power while the heater is operating.
