Control Panel
Water Temperature
Zenith Tudor water heaters are fully automatic, and may be left switched ON under the control of the variable
thermostat.
Nominal operating temperature can be varied from about 30°C to about 80°C.
Temperature should not be set to less than 50°C without due regard to regulations governing the storage
temperature of hot water.
Economy Setting
The economy setting "E" will maintain stored water temperature
at approximately 50°C. At the "E" setting, the temperature control
locates into a set position and a slight resistance will be felt when
rotating the temperature control beyond that setting. This measure
is to help ensure that higher temperatures are only selected
deliberately.
Frost Protection
If the heater is located where ambient air temperature could fall below 5°C when the heater is not in use, the
"anti freeze" setting on the temperature control will maintain stored water temperature over 5°C to prevent
freezing and damage to the water heater.
The same protection does not extend to connecting pipework or fittings.
Safety Cut-out
Should the heater over-heat, a manually resettable safety cut-out will automatically turn the heating element
OFF. The cut-out must be reset by a Zenith Service Provider or a licensed electrician. Users should never
reset the cut-out without qualified assistance.
