CHAPTER 3 - DHW SETTINGS (PRESTIGE, HEATMASTER AND INSTINCT SOLO)
DHW To CH Call Blocking sets the minimum time between a DHW
burner ring and a CH burner ring. At the completion of a DHW
burner ring, the DHW to CH Call Blocking time will begin. The burn-
er will not re again for a central heating call until after the DHW To
CH Call Blocking time has elapsed. This feature only prevents the
burner from ring, the central heating circulators will respond to a
central heating call. This blocking time has no eect on domestic hot
water calls. The DHW To CH Call Blocking feature prevents the burner
from ring when switching from a domestic hot water call to a cen-
tral heating call. This allows the remaining heat in the heat exchanger
to be dissipated and potentially satisfy the central heating call.
Adjust the DHW to CH Call Blocking value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 1 min.

DHW Call Blocking sets the minimum time between burner rings
for domestic hot water calls. At the completion of a burner ring, the
DHW Call Blocking time will begin. The burner will not re again until
after the DHW Call Blocking time has elapsed. The DHW Call Blocking
time only prevents the burner from ring, the domestic hot water cir-
culator will respond to a domestic hot water call. This blocking time
has no aect on central heating calls. The DHW Call Blocking feature
prevents short cycling of the burner and extends the life of the burn-
er components.
Adjust the DHW Call Blocking value using the LEFT or RIGHT
keys, then store the setting with the OK key.
