If it was stuck controllers would be pointless. The pint of going higher in the kitchen is higene. Wiring is not much just two wires generally and the controllers of the brands I know Rinnai and Reheem come with cable. One difference is Reheem the bathroom, kitchen and 3rd controller are different parts but Rinnai you can use 4 identical units and they sort themselves out and you do some button pressing to set the kitchen controller. OH Rinnai also has a wireless option too. You wire the wireless transmitter to the heater and away you go. You can also have 3 wired controllers too. But not much help if you have different brand. Re: Hot water control pads 14Jun 09, 2015 12:18 pm Ok thanks. We'll think about it after we move in.

The infinities have switches inside to change the max temp but turns out the model he had was fixed to max 50 and ignored the switches. We have a 24L Rinnai - probably 12 years old, and I remember we had problems with the low output of the shower head resulting in a sudden temperature drop so I downloaded a later version manual for the26e which has a diagram for all the dip switch settings ( jumpers ). I'm pretty sure by looking at the diagram - page 26, you can change one of the settings ( computer programming ) so that your neighbours issue is fixed. Stewie Re: Hot water control pads 16Jun 09, 2015 2:39 pm Have the same document, but that is what I was getting at in the post above. The model he had it didn't matter what you dd with the switches 50 was the max that could be selected. Apparently it was a compliance thing. No controllers out of box= fixed 50 degree max (even had a sticker on the front stating this), with controller you could change the maximum temperature using the switches, which then allowed you to choose higher than 50 on the nominal kitchen controller but max of 50 on the bathroom controllers. One thing I never have understood with this method is the controllers don't know what tap is running. So if the kitchen is master and set to 60 and you turn on a bathroom tap you get 60! Re: Hot water control pads 17Jun 09, 2015 10:30 pm I guess as you say if there is one model where you can't adjust the dip switches then that is that.

I would have thought that there would be a bit more electronic trickery built into them these days where the individual controllers "talked" to the main unit but obviously not, even allowing for the fact that it has a small computer chip inside.

Stewie It is not an issue of smarts in the controller, the issue is the controllers, nor the heater know which tap has actually be turned on. All that happens is a hot tap is opened somewhere, water flows through heater, heater senses this and decides to heat it to the temperature set on the controller that currently has priority. It wouldn't be hard to put a flow switch in a pipe to know what tap is opened, but that of course adds complexity and cost, and doesn't help much if two hot taps are turned on at once as which one has control? Re: Hot water control pads 19Jun 11, 2015 10:40 am Does anyone know if they help with priority? Example I am in the shower and my MIL (we are including a granny flat in our build) puts the tap on full blast down the other end of the house. In our current house, this seemed to cause an issue, frequent bursts of cold water in the shower. Re: Hot water control pads 20Jun 11, 2015 11:10 am Priority just means the controller with priority is the one that is setting the temperature. Controllers have no effect on water pressure though if you have controllers and only run the hot water tap when showering etc you won't get a temperature drop just a pressure drop. If you run hot and mix with cold then the same issue applies. But that would for the most part be a silly thing to do anyway. the sun master is the solar heating to "warm" the water in the tank the S26 is your hot water system which will heat the water (25 degrees?) so with both turned on you… 2 14571 I want to build a decking to the drawn shape outlined in black.
