Setting up combined heating and
battery charging
9.1 Setting up hot water heating
Warning:
If a thermostat is used to start the WhisperGen, it shall be set 5°C below the coolant
temperature set point, (refer to the control panel). If the thermostat is set higher than the coolant
temperature set point, the WhisperGen will not be able to heat the water in the hot water
cylinder/boiler to a high enough temperature to turn the WhisperGen off.
Warning:
The hot water cylinder/boiler shall have a heating coil length of 1 metre per 20 litres water
capacity, up to a recommended maximum of 10 metres.
A hot water cylinder/boiler with a minimum 40 litres capacity is recommended.
To set up hot water heating:
1.
Connect a thermostat to the hot water cylinder, and the External Digital In contacts on
the electronics enclosure.
2.
On the control panel, turn External Control to On, and select Mode 2. (Mode 1 can be
used if required).(Refer to the user manual for more information).
3.
Set the thermostat at least 5°C below the Temp Setpoint. This is to ensure that the
thermostat will open, and turn the WhisperGen off.
9.2 Setting up space heaters
The heat output (kW) rating of most commercially available space heaters is rated with a room
temperature of 20°C and a surface temperature, (coolant temperature), of 80°C. The maximum
coolant temperature setting for the WhisperGen is 70°C. To ensure that the full heat capacity
from the WhisperGen can be used, the size (heat output), of the heaters shall be 7.2kW. This
is equivalent to 6kW at 80°C.
Fan heating:
To connect a fan heater:
1.
Plumb the primary coolant through the radiator core.
2.
Connect the electric fan to a separate room thermostat to turn the fan on and off.
See
Figure 3
: Primary coolant circuit – series.
Convection radiator heating:
For convection radiator heaters, which are
fitted with a bypass thermostat valve
, plumb as for
fan heating.
For convection radiator heaters, which are
not fitted with bypass thermostat valves
, install
an additional heat exchanger and pump, and ensure that the pump is switched by the room
thermostat. See
Figure 3
: Primary coolant circuit – series
Additional heating device:
An additional heating device shall be fitted if the heat supplied by the WhisperGen is not
enough to meet the required heat demand. The WhisperGen will control the function of the
additional heater and only turn it on as required.
