Water Heater Setback Control:
This Setback Control works with the water heater gas control. It has the capability to adjust the
setpoint of the water heater during periods where little or no hot water is required for use. The
Setback Control adjusts the setpoint of a water heater similarly to the way a programmable
thermostat does for a furnace.
Setback Control Features:
•7 day / 4 period programming
•Conserves energy
•Hot water capacity indicator (provides an estimate of available hot water)
•Battery back-up stores programming during a power outage
•Can be programmed to comply with Sabbath requirements
•Similar interface to furnace / air conditioning thermostats
•Precision control of water temperature
CONGRATULATIONS!
You have just purchased one of the finest water heater accessories on the market today!
This Installation and Operation Manual will explain in detail how to install and operate your
new Setback Control. We strongly recommend you contact a plumbing professional for the
installation of this new control.
We require that you carefully read this manual and the manual supplied with the water heater
when questions arise. If you have any specific questions concerning your warranty, please
consult the plumbing professional from whom your Setback Control was purchased. For
your records, we recommend that you write the installation date for this control in the back of
this manual.
This manual should be kept with the Setback Control.
Important Information
-3-
The following terms are used throughout this manual to bring attention to the
presence of hazards at various risk levels, or to important information concerning
product life.
READ CAREFULLY
Indicates special instructions on
installation, operation or maintenance,
which are important but not related to
personal injury hazards.
NOTICE
Indicates a potentially hazardous
situation, which, if not avoided, could
result in death, serious injury or
substantial property damage.
WARNING
Indicates potentially hazardous situation,
which, if not avoided, may result in
moderate or minor injury or property
damage.
CAUTION
Indicates an imminently hazardous
situation, which, if not avoided, will result
in death, serious injury or substantial
property damage.
DANGER
NOTICE
This water heater is equipped with an energy cut out device to prevent overheating. Should
overheating occur or the gas supply fails to shut off, turn off the manual gas control valve to the
water heater and call a qualified service technician.
Whenever the water heater is filled with cold water, condensate will form on the cool tank
surface and drops of water will fall on the hot burner and combustion chamber surfaces
producing a “sizzling” noise. Condensation is normal and does not indicate a leak. It will
disappear when the tank becomes heated.
NOTICE
The lower the temperature setting, the greater the energy efficiency, both to heat the water and
to maintain the storage temperature during standby periods. Lower water temperatures also
extend tank life. Remember, no water heating system will provide exact temperatures at all
times. Allow a few days of operation at this setting to determine the correct temperature setting
consistent with the requirements for the installation.
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five (5) seconds at a
temperature setting of 140°F (60
°
C). To protect against hot water injury, install an ASSE
approved mixing valve in the water system. This valve will reduce point of discharge
temperature by mixing cold and hot water in branch water lines. A licensed plumbing
professional or local plumbing authority should be consulted.

scalded.
For energy efficient operation of your water heater, the suggested initial water temperature setting is
120˚F (49˚C). During the winter season, or any cold period, you may desire a higher water temperature
setting to adjust for the colder incoming water. This adjustment, however, may cause additional
condensation to form on the cooler tank surface. This does not mean the tank is leaking. During summer
months, the warmer incoming water temperatures will benefit the performance of your water heater and
reduce the amount of condensation developed.
Condensation does not mean your tank is leaking. Over 40% of reported tank leaks on installation are
proven to be condensation. To avoid unnecessary expense and inconvenience, make sure the tank is
leaking before calling a service technician.
As was stated previously, the recommended water temperature during periods when hot water is required
is 120˚F (49˚C). During setback periods, the recommended water temperature is 85°F (29°C). If it is
possible that hot water will be needed during the Leave and/or Sleep periods, set the Setback to 105°F
(41°C). This control may be used for the Sabbath. Please consult your local rabbi for recommended
water temperatures and appropriate times for the Sabbath.
Initially, the Setback Control will default all water temperatures to the setpoint on the water heater gas
control.
CAUTION
This water heater, when set at a lower temperature setting, is not capable of producing hot
water of sufficient temperature for sanitizing purposes.
WARNING
Do not operate the water heater or Setback Control without the Setback Control Junction Box
Assembly cover in place.
Do not operate water heater and Setback Control with jumpered or absent controls or safety
devices.
Turn off or disconnect the electrical power supply to the water heater and Setback Control
before servicing. Label all wires prior to disconnection when servicing controls. Wiring errors
can cause improper and dangerous operation. Verify proper operation after servicing.
All electrical wiring must be installed and grounded in accordance with local codes, or in the
absence of local codes, the National Electrical Code, ANSI/NFPA 70 and/or CSA C22. Electrical
Code.
