MONITOR RETURN TEMPERATURE:
The Manager continually senses the return temperature and will turn off the
zone outputs if the return temperature drops below 120
o
F (130
o
F if Option Switch #1 is ON). With the zone outputs
closed, the boiler water will quickly reheat and once the return temperature reaches 140
o
F (150
o
F if Option Switch
#1 is ON), then the Manager will reopen the zone valves.

THERMOSTAT SATISFIED
: The thermostat light on the left side will go out. The burner light and the burner will then
turn off.
8.
ENERGY RECOVERY
: The circulator and zone valve remain energized. The circulating water will remove the energy
from the converter, sending the heat to the last zone that called. The energy recovery stage continues until the return
temperature has dropped sufficiently or until maximum timing has been reached. The boiler is now sitting cold,
waiting for the next call for heat. Maximum timing for heat recovery stage is usually set at twenty minutes for space
heating zones and is fixed at five minutes for the Hot Water zone.

RECEIVING and UNPACKING
Inspect shipment upon receipt for external damage. When unpacking and uncrating, inspect each item for internal
damage. Any damage found should immediately be reported to the freight carrier before installation. The receiver is
responsible for following the claims procedure of the freight carrier. The freight carrier is responsible for taking prompt
action on all claims. If freight cannot be inspected at the time of delivery, sign the bill of lading “Subject to Inspection” and
inspect the shipment as soon as possible after receipt. Replacements for parts damaged in shipment are available upon
receipt of a signed copy of a claim report
(concealed damage claims should be filed immediately against the freight carrier
by the consignee).
After unpacking, check each item against the packing list. Inspect it thoroughly for loose parts, instruction sheets and
packing lists. Immediately report any missing items. It is wise to complete the installation before discarding packing
material. Store all parts where they will not be damaged or lost during installation.
