Modular Linking
A number of fan heaters can be connected together in a 'daisy
chain' fashion. A total of ten units can be controlled from a single
electronic control panel. The required connections can be made
in a daisy chain fashion as shown in Fig. 9. (References shown
below).
ECP - Electronic Control Panel
MU - Master Unit
SU
- Slave Unit
MLC - Modular Linking Cable
CPC - Control Panel Cable
To make these connections remove one of the small knock-outs
and feed an appropriate LAN cable (not supplied) to the BUS
OUT control socket ('D' in Fig. 9) of the Master Unit. Fix this cable
in the back panel using suitable cable gland (not supplied).
Continue this process for all linked heaters. Replace the control
housing of each heater and power up all units. Ensure that all
control settings function correctly.

one or a combination of the following abnormal events occurs:
1.
Air inlet or outlet grilles are obstructed.
2.
Internal ventilation is impaired due to build up of dust and
fluff.
3.
