Efficiency

The new controller makes the boiler more efficient by:

Setting the pre-purge timing optimum to the boiler
Purge Cancel function∗ converts the post purge time into pre purge time and allows for quicker response.
∗This function is not set as default

BL

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.
