Temperature Regulation

WARNING

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handi- capped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possi- ble temperature setting that satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves.

WARNING

Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bath- tub or shower.

Temperature Conditions

VERY LOW – The thermostat minimum setback tempera- ture is 60°F.

Programming the Thermostat

Before programming the settings on the thermostat, read the “Temperature Regulation” section again.

This new programmable thermostat technology makes it pos- sible for you to enjoy all the benefits of hot water whenever you need it and save the cost of heating water when you don’t need it.

Simple and easy to use, the programmable control has three basic modes of operation:

1.Manual mode – a set and forget operation.

2.Vacation mode – for those occasions when the residence is unoccupied and there is no need for hot water.

3.Programmable mode – can be programmed for up to 24 hour a day, 7 days a week with 4 set periods a day.

Override is an optional setting that allows for temperature adjustments during a given time period. This setting reverts back to the previous mode of operation upon completion of the designated override time period.

Option menu is a mode to change the factory setting for the time clock (12 hr. clock or 24 hr. military), temperature scale (°F to °C), default heating setpoint, vacation setpoint and maximum heating setpoint.

DATE AND TIME SETTING:

Your new programmable control comes complete with a day of the week and digital clock display. These settings are changed using the day and time keys on the control pad. To adjust day and/or time, depress the appropriate key button. The day of the week scrolls left to right on the display as the “DAY” button is depressed. The time setting can be adjusted by scrolling for- ward or backward using the + and - of the “TIME” button. The clock is based on a 24-hour rolling display with AM and PM appearing below the hour and minute characters.

CONSTANT TEMPERATURE DISPLAY:

The constant display screen shows the water temperature

“WATER TEMP” inside the tank. It is continually on dis- play until interrupted by a reprogram procedure, but reappears after 20 seconds of inactivity.

MODE CHANGE

To change the mode-of-operation depress the “MODE” but- ton at the bottom of the control. The mode display will change by scrolling from top to bottom with the Auto mode appearing on the top of the column, followed by the Manual mode in the middle and finally the Vacation mode at the bottom. Continue to change between mode settings by depressing the “MODE” button until the desired setting is displayed.
