Low Fire Hold with an RWF55 (continued)
Hot Water Boiler with an RWF55 with
Analog Output
1. Set the following parameters in the LMV5:
Params & Display > LoadController > Configuration > LC_OptgMode = ExtLC X62
Params & Display > LoadController > Configuration > Ext Inp X62 U/I = 0..20 mA
2. Set the following parameters in the RWF55:
ConF > Inp > Inp1 > SEn1 = type of RTD being used for temperature sensor
ConF > Cntr > CtYP = 2
ConF > AF > FnCt = 7
ConF > AF > AL = temperature to enable low fire hold
ConF > AF > HYSt = deadband around low fire hold temperature
ConF > OutP > FnCt = 4
ConF > OutP > SiGn = 0
3. Wire the LMV5 and RWF55 as shown in Figure 5:
Figure 5: Low Fire Hold via Analog Output on a Hot Water Boiler
See page 19 for an example of the low fire hold operation.
