DEFAULT SETTINGS & MENU ITEM DESCRIPTIONS HeatNet Control V3Page 94Default Settings & Menu Item Descriptions — ADVANCED SETUPDISTRIBUTED CTRLCONTROL H-Net Displays method of operation: HeatNet (H-Net)H-Net MASTER YESAuto detected, based on the HEADER sensor.If the HEADER sensor is present and is set to TYPEZ, the FuteraIII/Fusion-Series control is run as a H-Net MASTER (YES).If the HEADER sensor is not TYPEZ, H-Net MASTER = NO.MASTER TYPE AUTO AUTO, COMBO,DHWTwo PID controls are provided, one for Space heating and one forDHW heating. This menu item selects how they are to be used. TheMASTER TYPE setting is used to determine if the MASTER controlis to be used as a space heating control, a COMBO DHW/spaceheating control, or just to perform DHW Heating.When set to AUTO, the boiler uses one PID control to provide spaceheating. When set to COMBO, the control will use two independentPID controls to provide space heating and DHW heating. When setto DHW, the control only uses the DHW PID control.H-NET ADDRESS 255 2 –16The local address is the address of a Member device. This isnormally in the range of 2 through 16. But if the Futera III/Fusion-Series control is a MASTER, then the default address is 255. The H-NET ADDRESS # is synonymous with boiler #.MODBUS ADDRESS 1 1 – 247The MODBUS address is for communicating with Laptop, PC, orother MODBUS capable device, such as a Building ManagementSystem. It is the 2nd communication port reserved for host control.MODULAR BOILER SETSPACE HEATINGDHW HEATINGIf the MASTER TYPE is set to COMBO, the MODULAR BOILERSET is duplicated for each PID. Select SPACE HEATING to set theADD, SHED, MODULATE, and MOD MAX values for the spaceheating PID. Then select DHW HEATING to set the ADD, SHED,MODULATE, and MOD MAX values for the DHW heating PID.ADD BOILER DELAY 10mins 0 – 60minThis is the delay time in 30sec intervals, before starting a new boiler.Boiler #1 is started immediately after a call for heat. If a secondboiler needs to start, the ADD BOILER DELAY will need to expirebefore starting.SHED BOILER DELAY 2mins 0-15minThis is the delay time in 30 second intervals, before stopping aboiler. A boiler is stopped immediately when the top of the heat bandis exceeded. If a second boiler needs to stop, the SHEDBOILERDELAY will need to expire before stopping.MODULATE DELAYTIME 10 secs 0 – 60min This is the time the boiler remains in min-fire before it relinquishescontrol to the modulation % signal.MOD MAX – LAST FIRE 70% 25 – 100%This value represents the maximum % of input on the boilers if allthe available boilers are not firing. Once all boilers are firing, thisclamp is removed and all boilers are allowed to modulate up to100%. When this value is limiting the input an ‘*’ is displayed andthe “INPUT CLAMP” message is displayed in the STATUS screen.This value is derived by: multiplying twice the minimum fire rate ofthe boiler with the least turndown (2* turndown (20% 5:1, 25% 4:1,33% 3:1)). |
