Safety system and alarms
1. Switch the Darvall Cozy Heater on. The self-test starts.
2. All indicators on the Control Panel light up & the alarm sounds are tested.
3. This test indicates that the visible and audible alarm indicators are functioning correctly.
4. The LCD display will indicate when the Darvall Cozy Heater needs regular maintenance.
The Darvall Cozy has 2 sensors
1. Sensor1: Temperature Sensor in the hose outlet. (Inside of the hose nozzle)
2. Sensor2: Temperature Sensor in the air outlet. (At the elbow of the hose)
3. During the STS (Self-Test Sequence), the over-temperature alarm will sound then turn off
4. During normal operation NO temperature alarms should be displayed.
5. The temperature alarms sound if the temperature limits are exceeded, for example if the Darvall
Cozy Heater is set to warm to 43°C and the Heater Hose outlet temperature sensor 1 is outside of
43±3°C or Cozy Heater Outlet temperature sensor 2 is outside 53±3°C the over temperature limit
alarm sounds.
If a “Temperature Alarm”Condition occurs
1. Unplug the power and wait for 5minutes.
2. Reconnect the Darvall Cozy Warm Air Heater to a grounded power source. The Darvall Cozy
Heater should reset using the the normal STS sequence.
3. Select a temperature setting and turn the Darvall Cozy Heater. It should function normally
“High Level Temperature”Alarm Conditions
If the Darvall Cozy Heater senses that the Sensor 2 air temperature is above the 53±3°C range, the red
over-temperature alarm indicator illuminates and the alarm sounds within 5 seconds. At the same time,
the display flashes and shows “Over Temperature”. This alarm will continue until the temperature is
lower than 44°C.
The Darvall Cozy automatically turns off the heater and fan. You can press “ON/OFF” button to switch
the Darvall Cozy into standby mode.
If the High Level Temperature Alarm Condition re-occurs turn off the power and unplug the Darvall Cozy
Warm Air Heater from the wall outlet.

Temperature alarm OR if there is a High Level Temperature Alarm Condition, please contact the Darvall
Cozy Heater distributor or AAS Customer Service or a qualified service technician.
