6. Fault analysis and processing
Fault State Analysis of the Reasons Solutions
Power on, an the
Heater is no heating
• Power failure or no
power.
• The target temperature
is higher than
Thermostat on temp
• Heater failure.
• Check the power supply an
the electric circuit.
• Check the ambient
temperature to efine heater
Is failure or not
• Please contact Delta or
authorize Delta service
agent.
Power on, Heater is
always at heating
status.
• The target temperature
is lower than
Thermostat off temp
• Heater failure
• Check the ambient
temperature to efine heater
Is failure or not,
• Please contact Delta or
authorize Delta service
agent.
Power on, the Fan is
stop but the heating
is enable at low temp
con ition
• Fan lock
• Heater failure
• Power off pro uct than check
the Fan bla e is no block by
foreign matter
• Please contact Delta or
authorize Delta service
agent.
Power on, the Fan is
running but the
heating is isenable
at low temp con ition
• Over temperature
protect.
• Heater failure
• Check the heater air input an
output is no block, If the
heater surface is still hot, wait
for surface col own an
power on again at low temp
con ition for check the over
protect is clear or not.
