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 windows 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 temperature 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 subject-

ed to excessive moisture.

6. Once  an  area  on  the  exterior  wall  has  been

determined, to affix the enclosure use the enclo-
sure  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. Remove the sealing nut and 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 terminals 1
and 2.

2a. Cut a small slit in the seal gasket and route 18

AWG  2-wire  cable  or  similar  wire  cable
through the seal gasket into the enclosure.

3. Re-insert the sealing gasket and tighten the seal-

ing nut to the sensor enclosure.

4. Route  the  sensor  cable  back  to  the  appliance,

ensuring the cable is not route parallel to tele-
phone or power cables.

If the sensor cable is located in an area with

sources of potential electromagnetic interfer-
ence (EMI) the sensor cable should be shield-
ed or the wires should be routed in a ground-
ed metal conduit.  If using shielded cable the
shield wire should be connected to the com-
mon ground of the unit.

5. Connect the sensor cable to the outdoor sensor

terminals  on  the  24V  terminal  strip  located
inside  the  appliance  enclosure  (see  appliance
wiring diagram).
