Configuration Parameters

ref   Description default range
C1 FRST Frost protection level

Can disabled by setting FRST = 0 - (see Data Sheet for details)

3 2 to 15
C2 MAXF Maximum flow water temperature 80 30 to 110
C3 MINR Minimum return water temperature 40 10 to 50
C4 FLAV VT water temperature at 10°C outside temperature 50 20 to 80
C5 SACT Sensor Action

0 = use flow or return water sensors, if both present use average

1 = use flow water sensor

2 = use return water sensor

3 = average of flow and return water sensors

1 1 to 3
C6 BLRS Total number of boilers/stages available in sequence 2 1 to 8
C7 MXVT Maximum VT circuit water temperature 60 20 to 100
C8 VLIM Limits opening of the VT circuit valve if the return water temperature is below MINR.

Limiting is proportional over the band MINR to MINR-10°C.

0 = Valve will close fully if return < MINR-10°C

20 = Valve will close to 20% if return < MINR-10°C

100 = Limiting disabled, valve will follow demand.

100 0 to 100
C9 DHWP Domestic hot water priority

0 = Hot water and Heating have equal prioity

1 = Hot water has priority, VT pump will shut down when DHW requires heating

0 0 to 1
C10 MIN Boiler minimum run time 5 1 to 20 (minutes)
C11 BRON Primary pump run after all boilers off 1 0 to30

(minutes)

C12 PERD VT circuit valve stroke time 18 (180sec) 2 to 60 secs/10
C13 TRNG Flow setpoint trim, proportional effect from Zone demands 10 0 to 20
C14 CRNG Flow setpoint trim, adaptive effect from Zone demands 10 0 to 20
C15 MODE Zone actuator/valves operation

0 = actuators/valves match their zone heat demand

1= VT circuit forced on with valve fully open while boiler shut down in progress.

2 = as for 1 plus zone with highest heating demand sets actuator/valve 100%, other zones ratio output dependant on their heat demand. All actuators/valves open fully in BRON period (heat dissaption)

0 0 to 2
C16 BLOK Boiler stages available (i.e.. not in fault condition)   0 to 8
C17 AREM All boilers remote

0 = Boiler outputs on controller are included in sequence

1 = All boiler stages are via cascade modules. Boiler outputs on controller not used

 0 0 to 1
C18 SMRT Summer heating inhibit if outside temperature > SMRT 18 10 to 30
C19 MIND Minimum zone demand for boilers to run:

0: heating runs to heating setpoint for Occupation period

 2 0 to 10
C20 COMP Compensator offset 0 -50 to 50
C21 ALRM Alarm mode:
  • 0: No Alarms generated, no control action on event
  • 1: No Alarms generated, but disable boiler on event
  • 2: Generate LOKA/B Lockout Alarm and disable boiler on fault
  • 3: Generate GENA/B General Alarm but do not disable boiler on fault
  • 4: Generate STOP alarm if input ‘a’ in alarm condition (input ‘b’ operates as General alarm)
  • 5:Generate STOP alarm if input a in alarm condition, input b GENB shuts down Boiler if in alarm, used for pressurisation fault.


0

0 to 5
C22 ALST Alarm state

0 = Open circuit indicates Alarm

1 = Closed circuit indicates Alarm


0
0 to 1
C23 TYPE Output type : Not available from Zone Controller (Doorway only). Factory set to:
1 = Normal sequencing of stages

3 = Fixed sequencing of stages

 1 0 to 3
