Battery Backup; Recommended Timer On/Off Setting; Reset The Timer - Rheem Water Heater User Manual

The function of the timer is to enable the gas burner to automatically boost the
stored water temperature, if required, due to low solar energy gain during the
day. This will ensure the solar storage tank is full of hot water for the evening
hot water requirements.
Warning: The timer is not waterproof. Do not splash the timer with water.

BATTERY BACKUP

The timer has an inbuilt rechargeable battery. If a power failure occurs, the
rechargeable battery will maintain the memory of the timer, avoiding the loss of
any set programs.
Note: The rechargeable battery may be run down at the time of installation.
Connecting to mains power will recharge the battery.

RECOMMENDED TIMER ON/OFF SETTING

It is recommended the timer be set to enable boosting between
4:00 PM (16:00 Hours) and 6:30 PM (18:30 Hours). Note: The timer uses a
24 hour clock. This two and a half hour boosting period is sufficient to allow the
gas burner to heat up the entire contents of the solar storage tank through a
45°C temperature rise. This may be necessary during periods of very low solar
energy gain through the solar collectors, such as during constant rain or
extremely cloudy weather.
It may be necessary and is recommended to reset the timer during daylight
saving time (in the states where applicable), to enable boosting between
5:00 PM (17:00 Hours) and 7:30 PM (19:30 Hours), to maximise the solar
energy gain during this period.

RESET THE TIMER

It is recommended the timer be reset before commencing the initial
programming. This will delete any set programs.

Press the "R" button gently to reset the
timer. Use a non-metallic object like a
wooden or plastic toothpick.
Warning: Do not use a sharp
metal object as this may pierce the
protective membrane and an electric
shock may result.
Note: When the "R" (reset) button is pressed, the entire screen is illuminated
and all programs, including the current time, are deleted from the timer's
memory.
