Definitions
Caution
Rough-In Wiring
The following defined terms and symbols are used throughout this manual to bring
attention to the presence of hazards of various risk levels, or to important information
concerning the life of the product.
– Caution: Refer to accompanying documents.
– Caution: Refer to accompanying documents.
INSTALLATION
CATEGORY II – Local level appliances.
Improper installation and operation of this control could result in damage to the
equipment and possibly even personal injury or death. It is your responsibility to ensure
that this control is safely installed according to all applicable codes and standards.
This electronic control is not intended for use as a primary limit control. Other controls
that are intended and certified as safety limits must be placed into the control circuit.
Do not attempt to service the control. Refer to qualified personnel for servicing. There
are no user serviceable parts. Attempting to do so voids warranty and could result in
damage to the equipment and possibly even personal injury or death.
Choose the placement of the setpoint control early in the construction process to
enable proper wiring during rough-in.
Consider the following:
•
Interior Wall.
•
Keep dry. Avoid potential leakage onto the control. RH 80% to 88°F (31°C),
down to 50% from 104 to 122°F (40 to 50°C). Non-condensing environment.
•
No exposure to extreme temperatures beyond 32- 122°F (0 -50°C).
•
No draft, direct sun, or other cause for inaccurate temperature readings.
•
Away from equipment, appliances, or other sources of electrical interference.
•
Easy access for wiring, viewing, and adjusting the display screen.
•
Approximately 5 ft. (1.5 m) off the finished floor.
Use standard 18 AWG wire for the control power, relays, tN4 and sensor
connections.
Refer to the diagram below to determine the number of conductors to run from each
piece of equipment to the control location.

Remove the Wiring Cover
Mounting the Setpoint Control
To remove the wiring cover:
•
Place a small slot screwdriver or similar tool into the slot located on the top of the
control.
•
While pushing against the plastic tab, pull the top of the front cover so that it pivots
around the bottom edge of the control’s base.
If a single gang switch box is used, an Adaptor Plate 007 is required to mount the
control to the box.
•
Fasten the base of the control to the adaptor plate.
•
Feed the wiring through the openings in the back of the adaptor plate and control.
•
Use the upper and lower screw holes to fasten the adaptor plate to the box.

Do not apply power to these terminals. Serious control damage
will result.
The electrical drawing examples on the following pages show the 161 in common
applications. Choose the drawing that most accurately depicts the components in
your system and use that drawing as a guide to aid in wiring your system.
These are only concept drawings, not engineered drawings. They are not intended
to describe a complete system nor any particular system. It is up to the system
designer to determine the necessary components for and configuration of the
particular system being designed including additional equipment isolation relays
(for loads greater than the controls specified output ratings) and any safety devices
which in the judgement of the designer are appropriate in order to properly size,
configure and design that system and to ensure compliance with building and safety
code requirements.

•
Use screws in the screw holes to fasten the control to the wall. At least one of the
screws should enter a wall stud or similar rigid material.

Wire 24 V (ac) to terminals C and R.
If a Zone Manager is used:
•
Connect C on the setpoint control to C on the proper zone of the Zone Manager.
•
Connect R on the setpoint control to R on the proper zone of the Zone Manager.
If a 24 V (ac) transformer is used:
•
Connect C on the setpoint control to C on the transformer.
•
Connect R on the setpoint control to R on the transformer.

Troubleshooting the Wiring
General
The following tests are to be performed using standard testing practices and procedures
and should only be carried out by properly trained and experienced persons.
A good quality electrical test meter, capable of reading from at least 0- 300V (ac),
0 - 2,000,000 Ohms, and testing for continuity is essential to properly test the wiring
and sensors.

Testing the Wiring
Testing 24V (ac) Power Supply
1. Remove the front cover from the setpoint control.
2. Disconnect the wires from the relay.
3. Use an electrical test meter and check for continuity across the relay.
•
• When the relay symbol is displayed in the LCD, there should be continuity.
•
• When the relay symbol is not displayed in the LCD, there should be no continuity.
4. Reconnect the wires to the relay.
5. Install the front cover on the setpoint control.
Testing the Relay
1. Remove the front cover from the setpoint control.
2. Use an electrical test meter to measure (ac) voltage between the R and C
terminals. The reading should be 24 V(ac) +/– 10%.
3. Install the front cover.
