TEMPERATURE CONTROL

HIGH-LIMIT THERMOSTAT ADUSTMENT

 

 

 

 

A Honeywell high limit thermostat is used on both On/Off and Hi/Lo

 

 

water heaters (refer to “Location of Controls” on page 29.

The

 

 

thermostat has a capillary style temperature sensor located in a well

 

 

(pocket) fitted in the outlet header and senses the temperature of the

 

 

water leaving the water heater.

 

 

 

 

The high limit temperature setting is adjusted by removing the front

 

 

cover (loosen one Phillips-head screw) and turning the adjuster.

 

 

 

 

The high limit is reset by pressing the red button on the front of the

 

 

thermostat. It may be necessary to allow the system water

 

 

 

 

temperature to cool sufficiently before the high limit can be reset.

In general, the high limit should be set approximately 15°C above the operating temperature, however the following maximum limits must be observed:

Water Heating Applications: 90°C maximum.

Mechanical/Process Heating Applications: 99°C maximum for vented systems and 90°C maximum for unvented systems.
