What it is
The Timeguard TRT039N is a surface-mount digital heating programmer with four independently timed channels, giving separate 7-day control of hot water and up to three heating zones on a fully pumped central heating system.
Signs this part needs replacing
- Display is blank, dim, or unreadable even after checking the power supply
- Programmed times no longer trigger the heating or hot water
- Buttons stick or no longer register presses
- Clock repeatedly loses time or resets
Before you order
- Isolate the electrical supply before removing the old programmer
- Note your existing wiring configuration/terminal labelling before disconnecting
- Confirm this replaces a 4-channel unit (hot water + 3 heating zones), not a 2 or 3-channel model
