Introduction
Thank you for buying our touch thermostat. We hope
you will enjoy the ease of use oered by the touchscreen
and intuitively designed interface. You can program the
thermostat any way you want with the options provided
under Heating Schedule and User Settings.
The thermostat will switch on your heating system at
predetermined times each day of the week. You can set
individual temperatures for up to six separate periods,
called events, for each day of the week. Lowering the
temperature when your home is unoccupied will reduce
your energy costs without reducing comfort.
The thermostat comes with a preset heating schedule
suitable for most homes. Unless you change the settings,
the thermostat will operate according to this preset
heating schedule.
The thermostat features an adaptive function that
automatically changes heating start times to ensure
that the required temperature has been reached at the
beginning of any specific event. After a few days, the
adaptive function will have learned how much earlier the
heating must be switched on.
The resistive touchscreen only requires a soft tap with
your fingertip to register the touch.
In this manual, the touch areas on the screen will be
referred to as buttons.
The thermostat oers remotely control of your underfloor
heating - through the OJ Microline®MWD5 app, which
can be downloaded from both Google Play and App
Store.
With Google Home devices or Amazon Alexa devices
you can integrate with the thermostat. Once connected,
simply ask the Google Assistant or Alexa to turn the
heating up in a given room and let smart technology do
the rest.

thermostat to acknowledge the change.
“Accept” is shown on the screen as “√”.

corner of the touchscreen.
Tap the “Left Arrow” button to return to the previous menu.
“Cancel” is shown on the screen as a button marked “X”.
