BT - Temperature probe
BP - Pressure probe
IN - Manual burner stop switch
MB - Terminal strip
RS - Remote lock-out reset button (if present)
S - Remote lock-out signal
TL - Limit control device system: this shuts down the burner
when the boiler temperature or pressure exceeds the set-
point value.
TR - High-low mode control device system: this controls oper-
ating stages 1 and 2 and the TR load control is not re-
quired when the regulator RWF40 is connected as its
function is performed by the regulator RWF40 itself.
TS - Safety control device system: this operates when TL is
faulty.

The burner is factory set for two-stage operation
and the TR remote control device that commands
light oil valve V2 must therefore be connected.
WARNING
Alternatively, if single stage operation is required, instead of con-
trol device TR install a jumper lead between terminal 5 and 6 of
the terminal strip.
