Operating The Timers - Rinnai Timberflame IB35 ETR Operating And Installation Instructions

OPERATING THE TIMERS

OPERATING THE TIMERS
•
Before operating the Timer(s), the clock time must be correct and a starting time and finishing time
for the Timer(s) must be programmed. See page 5. The two Timers operate in the same way. This
heater does not commence operation at the programmed starting time. It will attempt to heat a room
by the programmed starting time. See Pre-heat page 6, for further explanation.
To select the Timer(s) to commence heating.
Check the time shown on the Digital Display is correct.
Check the ON and OFF times, for both Timers if necessary.
Press the ON/OFF button to operate the heater. The ON indicator will glow green and the heater will begin to
operate.
Select the desired temperature setting.
Press the Timer 1 and/or Timer 2 button(s). The timer indicator(s) will glow and the heater will remain on
standby until one hour prior to the time programmed into the selected Timer(s) is reached. When this time is
reached, the Timer indicator will flash and the heater will operate. The ON indicator glows red when the
heater commences operation.
SET AND FORGET OPERATION
•
Your heater can be operated to alternate between Timers automatically during cold weather by selecting
Timer 1 and Timer 2 together. Both Timer indicators will glow. The appliance will remain on standby at intervals
between the programmed finishing and starting times of each Timer. While the heater is operating during
programmed intervals the Timer indicator will flash.
If there is a power failure, the system memory will retain the Timer programs, and the clock will stop
at the time the power goes off. The clock will start again when the power comes back on, but the time
will be slow by the duration of the power failure. To set the clock to the correct time after the power
has come back on, simply follow the instructions on page 5.
PREHEAT
•
This function operates automatically in conjunction with either of the timers. When a timer is selected, the
heater may operate anywhere within an hour prior to the programmed starting time of the timer.
The preheat function will attempt to preheat the room by the programmed ON time.
This function is called pre-heat due to the way it operates. The room temperature is sensed one hour before
reaching the programmed time of either timer.
The temperature differential at the time of sensing the room governs how long before the program ON time
the microcomputer will operate the heater and ignite the burner.
