Help me understand my geyser timer

[blunt]

So we've just finished renovations and moved in to the new house and the previous owners (aged 92 and 95 - not getting any answers out of them) had geyser timers on the main board which I told the electricians to keep.

One of the geyser timers is pretty obvious with a clearly marked "On" indicator - https://www.dropbox.com/s/p9j4nb83jb5agec/Screenshot 2015-11-23 08.42.15.png?dl=0

The other one isn't so obvious - wonder if anyone can help me

Should I assume it's "On" to the left like the other?

Also, how do you set the time on these? Just make sure the dial is reflecting the current time and that's that?

Get an electrician to remove the timers and let the thermostat in the geyser work the way it should. My experience has been that I've actually used more electricity using a timer not less.

It looks to me like you manually move the dial in the direction of the arrow. The current time would be the time directly over the "-" sign. When you want the geyser to be on, you slide the yellow switch to the right (or left).

I would replace both timers so they are the same. I use the geyserwise product and it is great.

Timers on geysers work great if managed well.

1) schedule it around your usage pattern. Let the geyser finish its heating cycle before you get into the shower/bath.
2) when paying for electricity according to time of day use (off-peak vs peak time) it is common sense when to have it on to get cheap hot water.

Geyser timers generally suck.
If you have a dishwasher, then rather turn your geyser temperature down to 55ºC.
Geyser's are set to a factory default of 72ºC which is what runs your bill through the roof.
By turning my geyser down to 55ºC and switching it off manually for 12 hours a day my KWHrs dropped by 150 which at an average of R140 per unit is a saving of R210 pm.
If you live near or on the coast you can turn it down to 40ºC and still have excellent hot water.
