Water Temperature Adjustment

EGS-I&S-01

2.Aquastat satisfied.

a.Aquastat contacts open, turning off domestic hot water circulator and de-energizing relay.

b.Normally open contacts open, stopping boiler operation.

c.Domestic hot water priority only: Normally closed contacts close, returning boiler control to space heating.

1.The aquastat controls the maximum water temperature in the tank. The differential is a fixed 5°F with a 160°F maximum setting, set at the factory to 120°F.

WARNING

SCALDING

This water heater can deliver scalding temperature water at any faucet in the system. Be careful whenever using hot water to avoid scalding injury. By setting the aquastat on this water heater to obtain an increased water temperature, you may create the potential for scald injury. To protect against injury, you should install an ASSE approved mixing valve (a device to limit the temperature of water to protect against scald injury via mixing hot and cold water supply) in the water system. This valve will reduce point of discharge temperature in branch supply lines. Such valves are available from the manufacturer of this water heater or a local plumbing

supplier. Please consult with a plumbing professional.

Figure 5 - Scald Warning

Table 4 details the approximate relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.

APPROXIMATE

TIME/TEMPERATURE

RELATIONSHIPS IN SCALDS

120°F	More than 5 minutes
125°F	1 ½ to 2 minutes
130°F	About 30 seconds
135°F	About 10 seconds
140°F	Less than 5 seconds
145°F	Less than 3 seconds
150°F	About 1 ½ seconds
155°F	About 1 second

2.For the most energy efficient operation, adjust the aquastat for the minimum water temperature necessary to meet domestic hot water needs. Refer to Figure 6. Use a small flat screwdriver to rotate the temperature dial through the hole directly below the temperature indication window. The temperature setting is aligned with the notch in this window. IT IS NOT

NECESSARY TO REMOVE THE COVER TO ADJUST THE TEMPERATURE SETTING. THE AQUASTAT COVER SHOULD NEVER BE REMOVED WITHOUT ELECTRICITY BEING FIRST DISCONNECTED.
