6. set HW timer
This is a user function, and at this option the on/off times for hot water production may be set.
NOTE: This function is not appropriate to the Combi boiler and may be ignored. Hot water production
with the combi boiler is instantaneous and is available at all times.
Hot water production always takes priority over heating and the heating function will be temporarily
suspended whilst hot water is being generated. This applies to both the Strata 1-38 boiler and
Strata 1-38/46 Combi.
To set operational times for hot water charging follow the procedure as described in 19.4.5 a to l.
Default – on 0.600 – off 23.00.
