TEMPERATURE CONTROLS - GENERAL
When deciding on the best position for the temperature controls, the following points
should be taken into account.
• Fit the controls out of reach of children (suggested height from the floor 1.5m.)
• Avoid positions where the controllers will become hot. Do not fit them near stoves or
ovens, or above radiators or heaters.
• If possible, avoid exposure to direct sunlight or positions where bright lights will make
the digital display difficult to read.
• Position away from areas where the controller will be prone to splashing by cooking
products such as oils and fats.
• The temperature controllers are water resistant, however they should be positioned
away from areas where direct or persistent splashing could occur.
• Refer to the I.E.E electrical wiring regulations current edition for location requirements
in shower and bath areas.
• The cables to the temperature controller carry only 12VDC (extra low voltage.)
• When using more than one temperature controller the signal cable should be run in
parallel. That is, from controller to controller to heater, or from each controller to the
heater. Do not wire the controllers in series.
The installation in every application will vary, therefore the temperature controller cable
has been provided so that you may cut the length accordingly and fit the spade
connectors, ensuring a good connection.
Cables are simply ‘piggy-backed’ at the water heater or at the primary temperature
controller. Polarity is not important when connecting the cables, either colour wire can
be connected to either terminal at both the heater or primary temperature controller. If
more cable is needed any cable with similar specification to the cable supplied with the
controller can be used. Maximum length is 50 metres.
