Common questions about manuals, registration, and support for this brand.
To reset most Horstmann programmers, lower the front flap, and on the Heating channel press the ADVANCE and SELECT buttons together, then release. The programmer will return to preset factory settings.
The backup battery is integral to the unit and is not replaceable. Attempting to remove it will invalidate the warranty. It is designed to save settings for at least two years if the power is disconnected.
The manual boost timer provides up to 60 minutes of extra hot water during the day, outside of the normal off-peak overnight electricity schedule.
