symptoms
Check
actions
No heat output from
fan convector
Are there any lights on the control panel?
►
If NO:
Check mains ON/OFF switch is set to ON
Check power supply to unit is switched ON at fused isolator switch
Check fuse in power supply fused isolator
Is the Alarm/Boost light flashing?
(refer to Section 8.2)
►
If YES:
Heating system water temperature is less than 29°C (refer to
Section 8.2).
Is the boiler or heat pump operating?
►
If NO:
Check the boiler/heat pump controls are correctly set for it to
operate
If the boiler/heat pump is faulty, contact your installer/service
engineer
If YES:
Wait for the system water temperature to reach at least 29°C.
Is the heating system circulating pump
operating?
►
Check and contact your installer to investigate if there is a problem
Low room
temperature
Is the required air temperature correctly set on
the control panel?
(refer to Section 8.2)
►
Set required air temperature using the ON/OFF button on the
control panel.
Is the required temperature setting indicator
light flashing?
(refer to Section 8.2)
►
Set point temperature has not yet been reached. Wait until indicator
light stops flashing
Low heat output from
fan convector
Is the water flow through the fan convector
too low?
►
Check for low water flow
A simple test for low flow is if there is a noticeable temperature
difference to the touch between the flow and return pipes when the
unit is operating
Are the isolating valves on the flow and return
connections open?
►
Check and open valves if necessary
Are the flow and return connections reversed? ►
Check - the flow and return connections are indicated on the fan
connector.
The flow pipe should be hotter to the touch than the return pipe
when the unit is operating
Has the fan convector been completely bled
of air?
►
Check by bleeding any remaining air - as described in either Sec-
tions 3.7 or 3.8, as appropriate for the model of fan convector.
Are the flexible hoses twisted or kinked
(Solo Hideaway model only)?
►
Remove unit from plinth and check. Rectify as necessary.
