Product Description; Installation - D-D The Aquarium Solution DUAL HEATING & COOLING CONTROLLER Product Instruction Manual

PRODUCT DESCRIPTION

The Dual Heating and Cooling Controller is designed to allow for the precise control of
the temperature in both freshwater and saltwater aquariums.
The programmable controller constantly displays a real time temperature reading for
the aquarium and uses a accurate solid state NTC (negative temperature coefficient)
sensor, this is encased in a waterproof plastic housing allowing it to be fully submerged
in the aquarium or sump.
Operating two independent mains output sockets the controller can power both
suitable heating and cooling devices. One socket is dedicated to powering a heating
element raising the temperature in the aquarium and the other for operating a cooling
device lowering the temperature. The controller will automatically switch power to
each socket as needed to maintain the temperature within the users settings.
Aquarium heaters up to a maximum rating of 1600w can be connected to the heating
power socket. This socket is marked with an 'I' and a sun symbol. Heating elements
without built in thermostats, such a s the D-D Titanium Heaters, and standard glass
heaters with thermostats can both be used on this socket. If your heater has a built
in thermostat this must be set higher than the temperature set on the controller,
otherwise it will fail to operate properly.
The cooling socket, marked with an 'II' and snowflake symbol, can operate a fan for
evaporative cooling or a refrigerant chiller. The maximum rating for the socket is 1600w
but it is important that if a refrigerant chiller is used its operating power is no more than
600w, otherwise it may damage the control socket. This is due to the initial starting
power requirements for chillers as they will greatly exceed their rated operating power
during this time.

INSTALLATION

Position the controller and power socket in a suitable location away from open water
or splashing. Both of these components are not waterproof and may be damaged
if they become wet. The controller can be positioned using the hook and loop self
adhesive pads included and the power socket fixed in to place with the built-in screw
mounting point. We recommend that the socket is not installed flat on the base of a
cabinet near a sump in case water ingress from spills or leaks.
Position the temperature probe in an area of good water movement in the sump or
aquarium, ideally in an place of low light to stop excess algae build up on the sensor.
We recommend that the probe is positioned in the same area of the system as the
heater, e.g if the heater is in the sump the probe should be upstream of the heater in
the sump. It is important that it is kept fully submerged at all times and that it is not to
close to a heater or chiller outlet otherwise the controller will receive false readings
and will not operate properly. The probe should not be located where it can be drawn
in to a pump inlet or potentially physically damaged by the aquarium inhabitance (e.g.
Puffers, Triggerfish or Urchins).
Please note when performing a water change it is best to disconnect the power from
the Dual Heating and Cooling Controller as it will be reading the temperature in the
