Programable Weekly Timer - Rinnai RHFE-431WTA Owner's Operation And Installation Manual

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).
The two diagrams below graphically represent an example weekday and weekend program.
WEEKDAY PROGRAM

9:30pm

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.
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.
