BOILER THERMOSTAT OPERATION: ALARM OUTPUT AL2
This function is used to set burner ignition and extinguishing limits, with reference to the set point value.
To do this, the AL2 parameters must be used.
Connect LC3 terminals 8a and 9a to terminals T
1
and T
2
of burner connector (boiler thermostat).
Set the following parameter in the OUT parameter unit:
O3F = Al.nc normally closed relay
Set the following parameters in the AL2 unit:
AL2 = Hide Maximum relative alarm
AL2 = 5 Switching off delta compared to SP
HAL2 = 10 Switching on hysteresis compared to SP and AL2
Example below:
SP = 70°
AL2 = 5
HAL2 = 10
If temperature is above 75°C (SP + AL2), burner turns off.
When temperature reaches 65°C (SP + AL2 - HAL2), burner turns on again.
TWO-STAGE OPERATION
The dual fuel burners have a modulating operation when gas is used, and a two-stage operation when
diesel is used.
The AL1 alarm parameters must be used for two-stage operation.
Connect burner terminals 70 and 71 to LC3 terminals 4a and 6a.
Select the diesel fuel to enable digital inputs.
Set the following parameters in the AL1 unit:
OAL1 = OUT2 Output 2 enabling
AL1t = Hide Maximum relative alarm
AL1 = -15 Hysteresis for shift to first stage
Example below:
SP = 70°
AL1 = -15
If temperature ranges between 55° and 70° (SP + (-AL1)) burner operates with only one stage.
If temperature drops below 55°, burner operates in second stage.
