10.7 Parameter G - differential control
No. G1 Differential controller function
• non-existent
• 1 circuit
• 2 circuits
• External heat boiler
No. G2 / G2a Differential controller active / Differential controller switch-off
No. G2b Differential controller activated at external heat boiler
Set at which temperature (sensor S1) the differential control should become
active
No. G4 Circuit 1 (priority circuit) sensor selection
Set which sensor should be used for differential control
• Differential sensor S2
• Accumulator sensor top / mid. / bott.
• Accumulator sensor top mid / bott. mid
• HWT sensor A
.
No. G4a Differential controller superelevation
Set at which temperature the differential control should become active
Circuit 1 is activated when the sensor temperature (S1) is higher than the
temperature at the parametrised sensor (installer setting G4) by the preset
value.
Range: 1 - 50 °C
.
No. G4b Differential controller Switch difference
Indicate what the differential temperature between the two sensors being
used has to be. If it has dropped below, circuit 1 is activated.
Range: 1 - 50 °C
.
No. G4c Differential controller Shut down
Set from which temperature the differential controller should be deactivated
Range: 10 - 95 °C
.
No. G5 Circuit 2 (non-priority circuit) sensor selection
Set which sensor should be used for differential control
• Accumulator sensor top / mid. / bott.
• Accumulator sensor middle top / middle bottom
• HWT sensor A
.
No. G5a Differential controller Superelevation
Set at which temperature the differential control should become active
Circuit 2 is activated when the sensor temperature (S1) is higher than the
temperature at the parametrised sensor (installer setting G5) by the preset
value.
Range: 1 - 50 °C
.
No. G5b Differential controller Switch difference
Indicate what the differential temperature between the two sensors being
used has to be. If it has dropped below, circuit 2 is activated.
Range: 1 - 50 °C
.
No. G5c Differential controller Shut down
Set from which temperature the differential controller should be deactivated
Range: 10 - 95 °C
