Product Precautions
Honeywell TMG-740-3-MOD-43-35 is satronic tmg 740-3 mod. 43-35 burner control box. It sequences and supervises single- or two-stage forced-draught gas and dual-fuel burners using ionisation, UV or infrared flame detection.
- Controls forced-draught burner start sequences
- Supports ionisation, UV or infrared flame detection
- Provides continuous five-LED flame indication
- Implements the Mod. 43-35 timing programme
TMG-740-3-MOD-43-35 operates with TMG plug-in base, approved flame detector, air-proving switch, burner motor, ignition and fuel valves.
Engineered applications include Forced-draught gas burner control, Dual-fuel burner sequencing, Modulating burner supervision, Burner-control-box replacement.
Important Notice: Isolate burner power and fuel, verify the Mod. 43-35 programme, detector selector, base wiring and air-proving circuit, then repeat the complete burner safety test.

Apter Power Honeywell TMG-740-3-MOD-43-35 Product and System Technical Reference PDFApter Power Honeywell TMG-740-3-MOD-43-35 Installation and Commissioning Workbook PDFThe first document presents model-specific engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.
Forced-draught gas burner control
Sequences purge, ignition and fuel-valve operation.
Dual-fuel burner sequencing
Supervises flame during intermittent burner service.
Modulating burner supervision
Supports staged or modulating burner arrangements.
Burner-control-box replacement
Restores the exact timing programme and detector selection.
Read the applicable Honeywell instructions before work. Verify TMG-740-3-MOD-43-35 and the installed Honeywell Satronic burner control configuration.
1
Verify the complete TMG-740-3-MOD-43-35 marking and its assigned Honeywell Satronic burner control position before work.
2
Place the connected forced-draught gas burner control process in the approved maintenance state.
3
Isolate applicable power and burner purge, ignition, fuel-valve and flame-supervision signals field energy before disconnecting conductors.
4
Record connector, conductor, address, firmware and software identities before removal.
5
Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.
6
Confirm the installed TMG plug-in base and approved flame detector against the approved project.
7
Restore power in a controlled sequence and review device, network and host diagnostics.
8
Prove the intended dual-fuel burner sequencing function and retain the final test result.
Technical notes
Isolate burner power and fuel, verify the Mod. 43-35 programme, detector selector, base wiring and air-proving circuit, then repeat the complete burner safety test.
