INSTALLATION
CATEGORY II
– Local level appliances.
Caution
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.
Rough-In Wiring
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.

Mounting the Setpoint Control
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.
If a switch box was not used, mount the control directly to the wall.

•
Feed the wiring through the openings in the back of the control.
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.

Electrical Drawings
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.
