Please help - I have a Honeywell ST7100 heater/thermostat and there is no manual. I have tried to programme the hot water - but the red light continues to come on for the EXTRA HOUR - this is not required and I fear it is costing me extra money all the time. I do not need this. Where can I get assistance or read the manual on line please? Thank you.
