The anti-cycle time starts when burner shuts down during a CH call due to boiler water reaching the boiler set point temperature plus
a 6ºF [3ºC] dierential. The CH circulator will continue to operate while the burner is blocked.

For installations with an optional ACV- Triangle Tube SMART Indirect Fired Water Heater (I.F.W.H.) piped o the primary loop, similar to
Figures 7 and 8 on page 15, parameter 1 should be set to 1. The I.F.W.H. aquastat should be wired to CHALLENGER’s X4-5 and X4-6
electrical connector, see Figure 12, page 21. The domestic I.F.W.H. circulator should be wired using the CHALLENGER’s 120 V terminals
4 (line), 5 (neutral) and 6 (ground). During a domestic call for heat on terminals X4-5 and X4-6, only the domestic I.F.W.H. circulator will
operate and the boiler’s target supply water temperature will shift to 186°F [86°C].

The DHW post pump function only applies when parameter 1 is set to a setting of 1 Heating & Smart I.F.W.H. and only occurs if no CH
call for heat is present.
The anti-cycling time starts at the end of the DHW call and blocks the burner and CH circulator. If DHW function is turned ON (” ” LED is
lit above the “ ” DHW button) or ECO is ON (” ” LED is lit abobve “ ” DHW button) then the burner will continue to re for DHW until a
minimum heat exchanger temperature is achieved. Burner and CH circulator will continue to be clocked until the remaining wait time
ends. This feature only applies if parameter 1 is set to 0.
