Commissioning
Once the ceiling heater is functioning verify that the fans operate at Low, Medium and
High speeds, that there is no excessive mechanical noise coming from the fans and that
all fans are working. Establish that the air stream from the discharge grille warms up
when heating is selected. Confirm that heating increases as higher heat is selected.
Confirm the heater operates correctly in Manual Mode. Then select Auto Mode and
increase the heating set point until the air stream warms up. Reduce the heating set point
until the air stream goes cold.
Persons using the ceiling heater must be given adequate instruction and supervision
concerning the use of the appliance by a person responsible for their safety. The heater is
not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities.
Before leaving site it is important that the cassette heater installation is “Handed-Over” to
the end user or his representative and the operation of it is fully explained and that they
understand how it operates. Explain also the service intervals and that the unit must be
regularly cleaned.
Fault Conditions
Cassettair ceiling heaters are fitted with two internal electrical fuses located on the
ECONTROL board; 6.3A (T) supplies the fan motors within the cassette heater and
125mA (F) controls the operation of the ECONTROL power board.
If J2 link on the ECONTROL power board is missing, the LED’s on the remote control
will flash and the ECONTROL power board status LED on the board will be permanently
red to indicate a fault. In the case of a fault condition (refer to flowchart), a Biddle
appointed technician or certified electrician should attend the unit to investigate the
reason for the fault. Once the cause has been determined and rectified, they will verify
all the functions operate correctly.
PCB Status
Fitted on the PCB board inside of the ceiling cassette heater is an LED, shown as LED1
on the wiring diagram that will indicate the ECONTROL power control status.
1. LED flashing green – operation normal.
2. LED flashing red – low supply voltage or controller not plugged into ECONTROL
power motherboard.
3. LED permanently red – for LPHW model J2 link missing. Remote Control LED’s
will also flash to indicate a fault.
