Prestige Outdoor Temperature Reset Sensor Instructions

Fig. 27: Sensor Enclosure and Components
Mounting the Outdoor Sensor
1. Remove the front cover and mounting
screws / anchors from the sensor enclosure.
2. When mounting the enclosure the exterior
wall selected should represent the heat load
of the building. Typically a northern or
northeastern wall will suit most buildings.
A southern facing wall for those buildings,
which may have large glass walls or win-
dows on the southern face.
3. Ensure the sensor enclosure is shielded
from direct sunlight or the effects of heat or
cold from other sources (exhaust fans,
appliance vents...) to prevent false temper-
ature sensing.
4. Mount the sensor enclosure at an elevation
on the exterior wall to prevent accidental
damage or tampering.
5. Avoid mounting the enclosure in areas sub-
jected to excessive moisture.
6. Once an area on the exterior wall has been
determined, to affix the enclosure use the
enclosure as a template to mark the location
of the mounting screws.
7. Using a 3/16" drill bit, drill 2 pilot holes on
the marked locations.
8. Tap the enclosed plastic anchors into the
pilot holes. Use care not to damage the
anchors.
9. Mount the sensor enclosure using the
screws provided.
Wiring the Sensor
1. Unthread the sealing nut and remove the
sealing gasket from the sensor enclosure.
2. Route 18 AWG 2-wire cable or similar wire
cable through the sealing nut and gasket.
Connect the wire ends to the sensor termi-
nals 1 and 2.
3. Re-insert the sealing gasket and tighten the
sealing nut to the sensor enclosure.
4. Route the sensor cable back to the PRES-
TIGE boiler, ensuring the cable is not route
parallel to telephone or power cables.
NOTICE
If the sensor cable is located in an area
with sources of potential electromagnetic
i n t e r f e rence (EMI) the sensor c a b l e
should be shielded or the wires should be
routed in a grounded metal conduit. If
using shielded cable the shield wire
should be connected to the common
ground of the unit.
5. Connect the sensor cable to the outdoor sen-
sor terminals on the 24V terminal strip locat-
ed inside the boiler enclosure (see unit
wiring diagram, Fig. 17 page 30).
Summer / Winter Switch at Boiler
If required the CH (Central Heating) system
can be turned off at the boiler, similar to man-
ual summer / winter switch by press/hold the
the "StbY
