Operation
The Beckett 7600AWM (AquaSmart
Wireless Module) dynamically adjusts the
boiler high setpoint using the graph shown
in Figure 1 and inputs of the outdoor
temperature and user-confi gurable
setpoints as noted in the fi gure.
The WTM algorithm overrides the
HeatManager
TM
functionality of the base
AquaSmart when enabled. If the outdoor
sensor battery is depleted or if the sensor
stops working for any reason, the AWM will
revert the AquaSmart back to its
HeatManager
TM
algorithm until the battery
can be replaced.
In normal operation, the WTS sends the
AWM the outdoor temperature every 10 -
60 minutes. Pressing the WTS button
once forces a transmission.

The Beckett 7600WTM can help to
achieve even greater fuel savings over the
base AquaSmart with the following
advanced features:
Warm Weather Shutdown can be
enabled to turn the low limit (if used) off
if the outdoor temperature is above
70°F.
The boost function can be adjusted in
small increments to prevent the reset
algorithm from being overridden too
quickly, which can benefi t systems with
high water mass (such as in-fl oor
radiant heating applications).
The outdoor reset algorithm begins
economizing immediately after a
Domestic Hot Water (DHW) call for heat,
where the HeatManager takes time to
reach full economizing after a DHW call.
