Efficiency
The new controller makes the boiler more efficient by:
- Setting the pre-purge timing optimum to the boiler
Honeywell: standard 10s, IRI 30s
New controller standard 10s, IRI 20s
- Purge Cancel function∗ ignores the post purge when fast restart required. It eliminates the loss and shorten response.
∗This function is not set as default
When restart requirement occur during the post-purge, boiler consider post-purge time as pre-purge and shorten the pre-purge timing. It eliminates the loss and shortens response.
