TEMPERATURE CONTROLS
General Information
Commercial installations do not generally have controllers installed. These installations usually have one
permanent set temperature that is constant at all times. The public should not have access to alter the
temperature in these situations. These installations do not require controllers as the temperature can be
set by a series of dip switches on the PCB.
Exceptions to this are the following:
1.Circumstances where the required temperature is not available with the dip switches (for example
41°C or 47°C).
2.Circumstances where the temperature needs to be raised periodically by the building occupant in
order to flush the system.
3.Domestic situations where the user needs control of the temperature of the water so that different
temperatures can be used at different outlets.
In situations such as 1 and 2 the controllers should be installed in places out of reach of the public, such
as in the maintenance room or in a locked cupboard.
This
Commercial Setting will allow the controller to come back on automatically
after a power cut at the temperature set point previous to the power cut,
regardless of whether water is flowing through the unit. This should only be used
for commercial installations.
The maximum temperature available on the primary universal remote controller is the set point on the
dip switches. If only one controller is installed it will not go beyond 50°C when first installed. To bypass
this see
page 11 .
Positioning 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 local 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. 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 m.
