Smart Immersion Functions
On the new Smart Immersion we have four setting options:
Immersion Testing
Install the immersion using rigid cable, 2m long max, with 2.5 mm
2
cross-section and a temperature
resistance of at least 85°C.
The Cable should be rubber insulated HOFR sheathed, complying with BS6141 Table 8. It must be
fully earthed.
Ensure all terminal connections are securely made. Do not however use excessive force when
tightening the terminal screws.
Ensure that the power supply is disconnected prior to making any electrical connections. Provide
90mm length of cable for each of the Live and Neutral cables with 8mm of bare cable for connection
to the Immersion terminals.
Provide 110mm length of cable for the Earth cable with 20mm of bare cable for connection to the
Earth stud.
Make a circle with the bare Earth cable and tighten securely using the washer to the Earth stud.
Fit the Live and Neutral cables to the Immersion thermostat.
Ensure all terminal connections are properly tightened prior to commissioning
For installations with high water demands, or areas with hard water, Titanium immersions should
be fitted.
The thermostat should be set so that the water is heated to a temperature between 60°C and 65°C.
Water stored at temperatures below 60°C can result in bacteria growth and temperatures above
65°C can cause scalding.
The immersion stat has an integrated high limit stat which If the primary thermostat fails the limit
thermostat takes over and shuts the element off before the water can boil in the cylinder.
• OFF
• ECO – smart control: starts for 2 weeks at
70°C and then it will select automatically
storage temperatures through the day
• MANUAL – works as standard mechanical
thermostat can be set up to 70°C
• OPK (off peak) – this must be selected when
the cylinder is connected to the night tariff.
During the day time the immersion is not
connected and this would require the smart
control to be reset. When OPK is selected
it should be set at 60°C and working as a
standard thermostat. Alternatively the user
can select the manual mode.
