Figure 11 Logic sequence for Herringbone control panel
6 Control system
The control system must be installed in
accordance with the design specification.
6.1 Control panel design
Ambi-Rad control panels are available
either as standard units to control
single or multiple zones of heaters
utilising the Ambi-Rad black bulb
radiant thermostat. Special control
functions are available on request.
Herringbone control panels use the
logic in figure 11 to operate in a safe
and satisfactory manner.
6.2 Installation of control panel
To install the Ambi-Rad control panel
remove the plastic plugs from the four
9mm diameter holes in the back of the
control box. Using these holes fix the
box in a convenient position to a
suitable plugged wall or solid structure
with No. 10 gauge wood screws or
6mm diameter bolts or set screws.
Access to the holes may be gained from
the inside of the box without the
necessity of removing the wiring
chassis. Make the electrical connections
in accordance with figure 12a or 12b
and cut holes in the removable gland
plate provided in the box. Conduit or
strain relief glands should be used.
