HONEYWELL / RESIDEO TF 832.3 control box

Control box honeywell / RESIDEO
Type tf 832.3
220vac

For 1- or 2-stage oil power burners up to 30kg/
h capacity and intermittent operations.
Flame detection:
– Photoresistor MZ 770 S
– Infrared-flicker detector IRD 1010.1
– UV solid state sensor UVD 970

APPLICATION RANGE
The TF 830.3 or TF 832.3 oil burner safety control boxes
are suitable to control and monitor oil power burner up to
30 kg/h capacity (approved and certified according to
EN230).

TYPES AVAILABE
TF 830.3 1-stage operation
post-ignition time ca. 20 sec.
low voltage protection according to EN230
TF 832.3 2-stage operation
post-ignition time 2-5 sec.
low voltage protection according to EN230

CONSTRUCTIONAL FEATURES
The control box circuitry is protected by a flame resistant,
transparent plastic housing. It incorporates the thermomechanical, temperature compensated timer, flame check and reset circuits.
Manual reset from lockout is provided by a push button with
an integrated lockout signal lamp. A central fixing screw
locks the control box to the wiring base. The wiring base and
control box have a positive plug-in arrangement, making it
impossible to achieve an incorrect connection between the
two parts. A variety of cable entry points provides utmost
flexibility of electrical wiring.

APPLICATION NOTES
1. Flame control
The following detectors can be used for flame control:
– For yellow oil flame: photoresistor MZ 770 S
– for blue or yellow flame: infrared-flicker detector type
IRD 1010.1 or as alternative the UV solid state sensor
UVD 970.
Using the photo resistor MZ 770 S, the no flame signal is
generated at light levels below 3 Lux with respect to the
operating cycle of the control. According to EN 230 stray
light safety level has to be established in conjunction with
the accompanying burner.
Connecting the IRD 1010.1 or the UVD 970, the correct
wiring has to be observed.
2. Burner control
For burners without an oil solenoid valve, the burner motor
has to be connected to terminal 5.
3. Low-voltage protection
The start up of the burner can only take place if the mains
voltage is higher than a limit which is 15% below nominal
value. If the voltage drops below 160V, a start-up is prevented
or – without allowing to release the fuel – the control box
goes into lock out mode.
4. Safety
The design and control sequence of the TF 830.3 and
TF 832.3 control boxes comply with the currently applicable
European standards and regulations.
6. Mounting and electrical wiring
Wiring base:
– 3 earth terminals with additional terminal for burner
earthing
– 3 neutral terminals with internal permanent connection
to neutral terminal 8
– 2 independant spare terminals (S1 and S2)
– 2 slide-in plates and 2 easy knock out holes plus 2 knock
out holes in the base bottom faciliate the base wiring
