WIRING
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
™
EnviraCOM 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 Sen-
sor 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
enables the control to 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.
