CAUTION
Electrical Interference (Noise) Hazard.
Can cause erratic system operation.
Keep wiring at least one foot away from large
inductive loads such as motors, line starters, lighting
ballasts and large power distribution panels.
Use shielded cable to reduce interference when
rerouting is not possible.
1. Wire the EnviraCOM bus terminals 1,2, and 3 on the
DHW Module to the 1,2, and 3 terminals on the Envira-
™
COM enabled Aquastat, thermostat (if available), or
anywhere on the bus where access is available and
convenient. (See Fig. 2).
2. Connect the two 32003971-003 Temperature Sensor
wires to the TS terminals on the DHW Module.

OPERATION
General
The 50022037-005 Domestic Hot Water Module is a device
which, when connected to an AquaReset enabled Electronic
Aquastat with a 50022037-002 Outdoor Reset Module via the
EnviraCOM
prioritize a domestic hot water demand. The Aquastat resets
the present boiler temperature setpoint to the High Limit in
order to ensure hot water for domestic use is available. Once
the domestic hot water demand is satisfied, the DHW Module
directs the Aquastat to reset the boiler temperature setpoint
to once again follow the outdoor reset curve.
Shielded cable may be required if routing the Tem-
perature Sensor wires near/along high voltage lines,
motors or other electrical noise-generating devices.
Do not extend EnviraCOM cabling beyond 1000 feet.
Signal degradation may occur.
