▷
Plug X9 is not wired at the factory. In other words,
the burner heats at its full capacity.
▷
A capacity range from 60 to 100% can be se-
lected using a voltage or current signal. A sig-
nal sensor is connected to terminal X9 for this
purpose:
20 mA/0 V = maximum capacity,
0 mA/10 V = minimum capacity.
Burner Chip Card (BCC)
▷
All the data relevant to the device are saved
on the BCC and the internal device memory
(EEProm). In addition, the parameters are saved
on the BCC.
CAUTION
Danger of electric shocks!
– Before working on possible live components,
ensure the unit is disconnected from the power
supply.
– If the BCC is removed from the burner control
unit, the heater TR will be non-functional.
▷
In the event of faults which cannot be rectified
by authorized trained personnel, contact the
supplier.
▷
The BCC can be removed from the burner control
unit and submitted for diagnostic purposes by
agreement with the supplier.

Delay
▷
If no other fault is active, the TR can be readied
for use again by inserting a new BCC. The BCC
must be compatible with the TR 75 and the gas
type used.
Setting the switch-on delay
▷
If multiple heaters switch on at the same time,
there can be a gas and/or power shortage on
individual devices. To avoid this happening, ad-
just the switch-on delay using the potentiometer
on the burner control unit.
▷
The potentiometer is set to 0 s at the factory.
– +
▷
If necessary, a switch-on delay of 5 to 10 s can
be set between the devices.

After completing the wiring, close the cover
and the housing cover on the burner control
unit again.
8 Switch on the power supply.
▷
A circulating dash will be displayed when the
voltage supply is switched on to indicate that
the switch-on delay is running.
9 Release the gas supply.
0 Commission the heater.
Commissioning
CAUTION
To avoid damage to the heater TR, please observe
the following:
– The heater may only be commissioned once
it has been ensured that the heater, gas pipes,
mains voltage supply and room thermostat have
been installed by authorized trained personnel
according to the regulations.
– During the initial commissioning procedure, the
direction of rotation of the main fan must be
checked first, see page 9 (Checking the
direction of rotation of the main fan).
▷
The TR may only be commissioned using the
gas type specified on the type label.
