PS-R-02
Indoor Temperature Sensor
Installation and Operation Manual
The PerfectSense™ PS-R-02 Indoor Sensor is designed to sense temperature
at remote indoor locations and send this information to the PerfectSense
Thermostat. This sensor can be used with the PS4000 and PS5000
thermostat models. The sensor can be used as a stand alone sensor or as
part of an averaging network. Once a sensor is connected to the thermostat,
the thermostat's built-in sensor is no longer used. The thermostat's installer
set-up parameters should be modified to tell the thermostat that a remote
indoor temperature sensor is being used. The temperature reading on the
thermostat's display will be the temperature at the remote sensor location.
Please take time to read and understand these instructions as proper
installation of the PS-R-02 will ensure an accurate and reliable
temperature sensor.
IMPORTANT SAFETY INFORMATION
WARNING: ELECTRICAL SHOCK HAZARD – Turn off power
at the main power source by unscrewing fuse
or switching circuit breaker to the OFF position
before installing, removing, or cleaning this
thermostat/sensor.
WARNING: FIRE AND ELECTRIC SHOCK HAZARD – This
device should be installed by a qualified
service technician with due regard for safety
as improper installation could result in a fire
and electric shock hazard.
WARNING: FIRE AND ELECTRICAL SHOCK HAZARD – This is
a 24V AC low-voltage thermostat. Do not install
on voltages higher than 30V AC.
• Do not switch system to cool if the temperature is below 50°F (10°C).
This can damage your cooling system and may cause personal injury.
• Do not short (jumper) across terminals on the gas valve or at the system
control to test installation. This will damage the thermostat and void
the warranty.
• All wiring must conform to local and national building and electrical
codes and ordinances.
• Use this thermostat and sensor only as described in the manual.
OVERVIEW
The PS-R-02 temperature sensor includes the sensor with lead wires
attached. It is secured to an indoor wall surface using screws. The PS-R-02
temperature sensor is connected to a thermostat as an external sensor.
The thermostat must be configured appropriately.
When installing this product:
1. Read these instructions carefully. Failure to follow them could damage
the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on the product to make
sure the product is suitable for your application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out the product operation as
provided in these instructions.
WARNING: ELECTRIC SHOCK HAZARD – Can cause electrical
shock or equipment damage. Disconnect power
supply before connecting wiring.
SET-UP
Mount the sensor about 4.92 ft (1.5m) above the floor where there is
good air circulation so it can measure true indoor ambient temperature.
Be sure the mounting surface is flat and the wire distance between the
PS-R-02 and the thermostat is less than 19.69 ft (6m), Figure 1.

Figure 1. Typical locations for indoor sensor
Make sure there is good air circulation and average temperature at the
chosen location. Avoid the following locations because they can introduce
errors in sensor measurements, see Figure 1.
Hot areas caused by:
• Concealed pipes or ducts
• Drafts from fireplaces or other heat sources
• Convection or radiant heat from the sun or electrical equipment
Cold areas caused by:
• Concealed pipes or ducts
• Drafts from doors or windows
• Unheated areas on the other side of the wall location
Dead air areas:
• Behind doors, furniture and curtains
• In corners and alcoves
Mark the area on the location selected for attaching the sensor. Use the
screw holes in the back plate as a template.

WIRING
CAUTION: ELECTRICAL INTERFERENCE (NOISE) HAZARD
Can cause erratic temperature readings and
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.
Make certain the wiring connections are secure.
WARNING: ELECTRIC SHOCK HAZARD – Can cause electrical
shock or equipment damage. Disconnect power
supply before connecting wiring.
Wiring must comply with applicable codes, ordinances and regulations.
Wire the PS-R-02 indoor sensor to S1 and S2 terminals on the thermostat.
If the lead wire provided is not long enough (9.48 ft [3 m]), run a color-
coded, 18 gauge 2-wire to the mounting location, refer to Figure 3. Pigtail
wiring may be used.
Push excess wire back into the hole. Plug the hole using nonhardening
caulk, putty or insulation to prevent drafts from affecting performance.
Remove PS-R-02 cover. Mount the PS-R-02 to the wall or junction box
using the screws and anchors provided. Level the PS-R-02 for appearance
only. The sensor functions correctly even when not level. Reinstall the
PS-R-02 cover.

CHECKOUT
The PS-R-02 indoor temperature sensor converts indoor ambient
temperature to a resistance that the thermostat can interpret.
The PS-R-02 has a negative temperature coefficient (NTC), which means
that resistance decreases as the temperature increases. Refer to Tables 1
and 2, Sensor resistance at room temperature.
With an accurate thermometer [+/- 1°F (0.5°C)] measure the temperature
at the sensor location, allowing time for the thermometer to stabilize
before reading.
To verify sensor resistance, remove one wire from the PS-R-02 remote
sensor. Use an ohmmeter to measure the resistance across the sensor.
Then verify the sensor accuracy with the temperature/resistance in
Table 1 or 2. Any difference in the temperature readings may be offset
using the thermostat's settings.
CALIBRATION
The PS-R-02 indoor sensor is calibrated at the factory and cannot be
recalibrated in the field.
