heating which warms your rooms from the ground up.

Specifically designed for underfloor heating, these thermostats can be mounted either vertically or
horizontally to suit individual needs. They come with a 2P Isolator / 16A Output relay.
The thermostat also comes with a programmable time clock which can automatically change the
temperature up and down at certain times. When the unit is in a down period, the heating doesn’t
turn off; instead it programs the temperature to the customers selected “set back” temperature.

To ensure a successful remote connection, you must have the following:

1. Make sure you are logged into your SWATT OJ App.
2. Make sure each thermostat you have is connected to the WiFi network.
3. If there is no WiFi connection available, try turning your router off and on. The thermostats
might be too far away from the router to join the WiFi network. The thermostat requires a
WiFi connection for the remote control.
4. Make sure your WiFi network is connected to the internet. Please note that sometimes you
can be successfully connected to the WiFi network, but your internet could be down. If this
is the case, you will have to check your router and connection with another device.
5. IF you server is not connecting it is either your WiFi, internet or the SWATT OJ server is
down. Alternatively, you can contact Speedheat Melbourne on [phone].
Using the App
The SWATT app divides your heated area into zones and within each zone are the thermostats that
have been grouped. By grouping thermostats into zones, this allows you to set all thermostats in the
same zone to the same schedule and temperature. If you do not wish to do this, you can also
program each thermostat separately.
Should you only have a single area with Speedheat Underfloor Heating we recommend keeping it
rather simple. i.e. name it Bathroom and the zone name Home.
Each zone is presented on a list and shows the thermostats within that zone.
MWD5 Menu on the App
On the App, you have the following functions to choose from:
Set up schedule: Allows you to programme individual heating schedules for each of your zones.
These can only be created for each zone and not a single thermostat.
Holiday: When you’re away, use this setting to keep your floors off during these periods.
Frost Protection: The will ensure that your floor will always stay above freezing point.
Manage Zones: With this function, you can create, edit, move, delete and rename zones and
thermostats you have added.
- Drag and drop your thermostats in different zones
- Tap zones and/or thermostats to rename them
- Drag and drop zones and / or thermostats into the bin icon to delete them
Energy Use: Should you wish to view usage for each thermostat.
Thermostat Information: Shows the details of each thermostat installed.
