My viveiro storage heaters.

[personnel]

My viveiro storage heater give out maximum heat when I am at work. It has three controls on the side, and I am not sure how to set them correctly.  Is it possible to change the timings, and how do I do it?

i have these in a house i let. you cannot adjust the timers if they are on economy seven. just close the vents on them whilst you are at work and open them when you get home
