IDWH Sensor Installation & Wiring
2. Remove the front jacket panel of the PRESTIGE by
removing the thumb screw along the upper edge of
the jacket panel. Once the thumb screw is removed,
pull the panel slightly forward and lift up.
3. Route the wiring from the Sensor to the PRESTIGE
boiler. Once at the PRESTIGE, route the wiring
through the PRESTIGE wire access openings and
along the wire ways inside the PRESTIGE.
4. Disconnect the bottom half of the PRESTIGE’s low
voltage terminal block. Strip the wire ends and attach
to terminals 11 and 12 using the terminal block wire
tool supplied with the PRESTIGE. See Fig. 6.
5. Once the wiring is attached to the terminal block,
reconnect the terminal block to the terminal strip.
Ensure the connection is complete and secure.
6. Replace the PRESTIGE front jacket panel and
secure with the thumb screw.
7. Restore power to the PRESTIGE boiler.

Install the IDWH Sensor (provided with water heater)
into the bottom coupling of the water heater as shown in
Fig.5.
Ensure the IDWH Sensor is tight and leak free.

ELECTRICAL SHOCk HAZARD. Turn power off to
the PRESTIGE boiler before proceeding with instal-
lation of the control wiring. Failure to comply could
result in severe personal injury, death or substantial
property damage.
1. Connect 18 gauge wire or thermostat type wire to
the IDWD Sensor terminals on the water heater
using standard 1/4" female insulated connectors.
In lieu of using insulated connectors, the IWH
Sensor connectors may be removed and standard
wire nut or splice connectors may be used. Ensure
the Sensor wire ends are stripped a maximum 1/4"
from the ends.
