General

Honeywell/ Satronic TF 834.3 / 836.3 for 1- or 2-stage oil power burners up to 30kg/ h capacity with or without oil preheater and intermittent operations. Flame detection:

• Photoresistor MZ 770 S
• Infrared-flicker detector IRD 1010
• UV solid state sensor UVD 970.

Features:

• The control box circuitry is protected by a flame resistant, transparent plastic housing. It incorporates the thermomechanical, temperature compensated timer, and 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.
• The TF 834 and TF 834 E are fully compatible with the TF 734 and TF 734-2 respectively.
• Using the TF 83X.3 as a replacement, the flame detector IRD 911 must be replaced by its compatible type IRD 1010. An optional extension button (item no. 70601) compensates for height differences.
