Using MCO Touch Panel with Storage Water Heater

I am using the Ariston Andris Lux 15L storage water heater which I bought from Sim Siang Choon (IMM) for S$280.

Li Xiang and I are typical working adults. We leave the house at 9am, and return only after 9pm. Sometimes we will forget to switch off the storage water heater and there goes a few dollars to the electricity bill.

The light indicator on the default switch is so tiny that you can miss it sometimes. It is not obvious enough.

We will also wake up about 30 minutes earlier to switch on the storage water heater and go back to sleep so that we can have a hot shower in the morning.

Since I am already using MCO Touch Panel for all my lights in my house, I decided to get another MCO Touch Panel (1 Gang MH-S411) at S$130 from Automate Asia to replace the switch of my storage water heater.

Installation of the MCO Touch Panel for the storage water heater is different and slightly more tedious than the installation for lighting.

It still needs the usual extra signal cable and an electrical contactor.

Since lighting uses less power, the load can be taken on by the MCO Touch Panel.

However, for storage water heater, it uses a lot of power and the MCO Touch Panel will not be able to take the load.

It needs a device to proxy the power, in this case the device is known as the electrical contactor.

So your MCO Touch Panel will switch on/off the electrical contactor and in turn the electrical contactor will switch on/off the storage water heater.

You can get a hager electrical contactor for probably less than S$50.

If you need a electrician to do the installation for you, feel free to contact Automate Asia.

Finally, I can set my storage water heater to be switched on at 7.30am from monday to friday and have it switched off when we leave the house!
