For installations with an optional ACV- Triangle Tube SMART/COMFORT Indirect Fired Water Heater (I.F.W.H.) piped off the CHALLENGER, similar
to Figures 7 and 8 on page 14, parameter 1 should be set to 1. The I.F.W.H. aquastat should be wired to CHALLENGER’s X4-5 and X4-6 terminals,
see Figure 12, page 19. The I.F.W.H. circulator should be wired using the CHALLENGER’s 120 V terminals 4 (line), 5 (neutral) and 6 (ground).
During a DHW call for heat on terminals X4-5 and X4-6, only the DHW circulator will operate and the boiler’s target supply water temperature will
change to 186°F [86°C].

The DHW post pump function only applies when parameter 1 is set to 1 Heating & SMART/COMFORT I.F.W.H. and only occurs if no CH
call for heat is present.
