PROGRAMABLE WEEKLY TIMER
The Rinnai 431WTA features a weekly timer which allows four separate time periods, each with its own temperature,
to be set.
These periods can be programed differently for each day of the week, or for a group of days: weekdays, weekends
or all days of the week together.
The four timer periods create up to four separate operating intervals, each with its own temperature setting.
The programing covers a 24 hour time span(one day).
A detailed step-by-step guide of setting the times and temperatures shown in the two examples above are given on
pages 28-29.
Before setting the heater we encourage you to think about and write down your own program. A blank table is provided
on page 31 for you to do just this.
The example weekday
program period 1 has been
programed to start at 5:30
am with a temperature setting
of 76 F.
The heater will heat the room
to 76 F from 5:30 am until
8:00 am, when period 2
starts.
Period 2 has a temperature
setting of “nothing” or OFF,
and so the heater will not
operate again until the start
of period 3 at 5:00 pm, when
it will heat the room to 72 F.
Period 4 turns the heater
OFF again until period 1
starts the timer cycle on the
next day.
The two diagrams below graphically represent an example weekday and weekend program.
For example if you get up
later on the weekends
period 1 begins heating the
home to 76 F at 9:00am.
The heater has also been
programed to start heating
the home earlier in the
afternoon, and so period 3
starts at 4:00pm with a
temperature setting of 72 F.
Period 4 now has a
temperature of LOW [50 F],
and runs the heater on this
setting all night.
