The thermostat can control up to
four different periods per day.
- Occupied1
Period to keep space at a
comfortable temperature, i.e.
first thing in the morning.
- Unocc1
Period to keep space at an
energy-saving temperature,
i.e. when leaving for work.
- Occupied2
Second occupied period, i.e
coming home from work.
- Unocc2
Second unoccupied period,
i.e. when going to bed.
The thermostat is usually
configured to have four
programmable periods. If you
would like to change this to two,
refer to the Advanced Settings
section (0540) in this guide.
The thermostat, dependent on
the buttons pressed, walks you
through the programming sections
available. To get familiar with how
this works, walk through some of
the steps below without changing
anything. Once comfortable with
how the display works you can
change the respective settings to
suit.
Ignore any settings relating to
cooling by selecting ‘Next’, these
have no effect on the iHeat
operation (this only appears as the
thermostat is also used for other
applications).
1. Press ‘More’.
2. Press ‘Schedule’.
3. Press ‘Edit’.

change the schedule period.
8. Press ‘Next’. The selections
automatically cycle through
period, time, and temperature.
9. Use the up and down keys to
modify the flashing item (e.g.
time, temperature).
10. When complete press ‘Done’,
this will save all of the changes
that have been made and
‘Saved’ will appear on the
screen. To exit scheduling
without saving, press ‘Cancel’.
If that option is not available,
press ‘Go Back’ until ‘Cancel’ is
available.
Tip
If you find yourself in a totally
different area of the program and
don’t have an option to ‘Go Back’
or ‘Cancel’, let the display flash
without pressing any buttons.
After approximately one minute
the screen will go back to the main
display.
The system when in timer mode (programmable) is on heat with the fan on auto. It runs on
timers and is on all the time. Setup number 160 = 4 (refer to p. 11)
