HYDRAULIC CONNECTIONS

The Grant Aerona Smart controller can be utilised in a number of
ways via the Smart controller configuration creator and settings
configuration.
The enclosed hydraulic schematics demonstrate typical setups
associated with the Grant renewables price list installation packs -
available from the Grant UK website.
Refer to the Grant Aerona Heat pump manual provided for further
information regarding sealed system & DHW considerations.
Refer to Section 5.4, 5.5 and 5.6 for corresponding electrical
connection drawings.

HYDRAULIC CONTROLS

4.3.1 THERMOSTATIC PUMP BLOCKADE
Thermostatic pump blockade is a hydraulic control feature within
a heating circuits setting that enables the Grant Aerona Smart
controller to either switch a circuit pump/valve OFF (Pump
blockade ON) or keep the circuit active (Pump blockade OFF)
based on the status of the thermostat monitoring the circuit.
Refer to Section 7.8 for further details on how to activate and use
this function.
4.3.2 CIRCUIT STOP FROM PRESET TEMP
'Circuit stop from Preset temp' is a hydraulic control feature within
a mixing heating circuits setting that enables the Grant Aerona
Smart controller to either switch a circuit pump/valve OFF (Circuit
stop on Preset temp ON) or keep the circuit active (Circuit stop on
Preset temp OFF) based on the status of the water temperature
sensor on the flow in the circuit.
Refer to Section 7.8 for further details on how to activate and use
this function.
