Operation
With the Automatic DHW Boost Kit 3 fitted, the HW cylinder
thermostat should be set to 47°C for optimum operation. When the
heat pump raises the cylinder to this temperature the cylinder
thermostat will be 'satisfied'
The time boost kit should be set as required to raise the temperature
in the cylinder to 60°C, usually for an hour or two weekly, or as
determined by the installer to match the occupants requirements.
If an amount of hot water drawn off is small, the temperature drop in
cylinder may be minimal and the cylinder thermostat may not detect
it. In this case the cylinder thermostat will continue to supply the
fused timer spur switch - 7 day
demand to the Boost Kit and the Immersion heater will continue to
operate.
