Notes..
  Smartfit 
Honeywell,  has swept aside the traditional problems and hasslesassociated with controls wiring and significantly reduced installation time andcosts into the bargain.
At the centre of Smartfit is a new connection box whichprovides plug-in or simple 2-wire connection for all space heating and hot watercontrols, completely eliminating the need for complex wiring diagrams.  Allthe controls have been designed for low voltage, polarity free connection.  Servicing  is quicker, chances of error are reduced to the minimum, and can beachieved with total confidence.  The elegant Smartfit controller puts easy programming and diagnostics at yourfingertips.  A built-in commissioning sequence and simple manual overridesassure maximum user convenience.
The unique built-in diagnostics programme automatically indicates a fault inthe system and highlights where the fault lies, cutting out guesswork and hassleand saving valuable time.

Stowaway Heat Bank Thermal Stores require an external 15mm copper overflow connection to be made. Plastic pipe should not be used. The overflow should be run to a minimum distance of 150mm above the top of the Heat Bank Thermal Store, terminating within 5m above or below the Heat Bank Thermal Store.
The unit is fitted with one heat exchanger, capable of delivering 30 litres/minute @45°C (80°C storage). The graphs shown the domestic hot water output that can be achieved for various storage temperatures.

  
 

A Mains Water Isolating Lever Valve must be fitted within the cylinder cupboard, in clear view and easily accessible. A Strainer (supplied loose) must also be fitted, down stream of the isolating valve, to protect the flow switch [4].
It is advised that the mains water is tested for hardness. In areas of hard water, we advise the use of a scale inhibitor.
A chemical corrosion inhibitor, such as Sentinal X100, must be added to the stored water within the cylinder. Anti-freeze should also be added where there is a possibility of prolonged exposure to sub-zero temperatures.
