You can change the heater's current mode by tapping the mode buttons. You can adjust
the mode's temperature using the + and – buttons when you're on that mode.
Scheduling your Heating
You can program your heating by creating a schedule of "events", where the heater
switches on or off. These events can be temporary, like setting a timer, or they can be
recurring, so the heater switches on at the same time every week. You can set an
unlimited number of events, switching the heater on and off across the week.
For every event, you must set a start time. Then, choose whether you want it to
repeat. Select "Only Once" if you just want to set a timer for now. If you want the
event to repeat, select which days you want it to occur. Finally, choose whether you
want the heater to switch on or off. Make sure you confirm your settings at every
stage and press save to keep the event.
Each event will appear in your schedule. You can activate and de-activate events
using the toggle. You can also delete events by swiping left and tapping Delete.
The heater will beep when it begins a new heating event. The heater will heat at
whatever mode it was last set to: you cannot schedule mode changes. Note, if you
change the heater's setting during an event – i.e. turning it on when it is scheduled to
be off – the heater will remain as it is until the next scheduled event.
