Section 1 — Introduction
Section 1
Introduction
The SetPoint 501 and 501s Controllers are microprocessor-based controls
that are designed to sense the air temperature in a specific area and
increase the comfort level of that area as well as increase the energy
efficiency of the heating system. The 501s will also monitor
slab temperature.

Installation
Getting Ready
Check the contents of this package. If any contents listed below are
missing or damaged, please contact your Uponor sales representative or
distributor for assistance.
• SetPoint 501 (part number A3040501) includes one controller, an
Installation and Operation Manual and a User Manual.
• SetPoint 501s (part number A3041501) includes one programmable
Setpoint Controller, one Floor Sensor (part number A3040079), an
Installation and Operation Manual and a User Manual.
Removing the Front Cover
1. Place a screwdriver or similar object into the
small slot located in the top of the controller.
2. Push the screwdriver against the plastic tab
and pull the top of the front cover so that it
pivots around the bottom edge of the base.
(See Figure 1.)
Mounting the Base
1. Install the controller on an interior wall of
the desired zone approximately 5 feet (1.5m)
above the floor.
Note: Do not mount the controller in a
location that may be affected by
localized heat sources or cold drafts.
2. If necessary, install a draft barrier behind
the controller to prevent air from blowing
through the wiring hole and affecting the
controller’s built-in sensor.
3. Mount the base directly to the wall using
two #6 1-inch screws. (See Figure 2.)
4. Insert the screws through the mounting
holes, and fasten the base securely to the
wall. If possible, at least one of the screws
should enter a wall stud or similar surface.

Mounting the Base
5. If the controller is mounted to a 2x4 electrical box, order a Cover Plate
for the 500 Series Controllers (part number A3040007). This plate
mounts to the electrical box and the controller mounts to the plate.
Ensure that the electrical box does not provide cold air to the controller.
Note: If the SetPoint 501s is used for remote sensing (i.e., the built-in
air sensor is disabled and an indoor sensor is used), mount the
controller in the desired location.
Rough-in Wiring
Note: 18 AWG or similar wire is recommended for all 24VAC wiring.
1. Strip all wires to
1
⁄4" (6mm) to ensure proper connection to the control.
2. Run wires from the 24VAC power to the controller. Use a clean power
source to ensure proper operation.
3. If using an optional sensor, install the sensor according to the appropriate
instruction sheet and run two wires from the sensor to the controller.
4. Run wires from the heating device to the controller.
Wiring the Controller
Refer to the wiring examples on page 5 to properly wire the controller.
1. Connect the 24VAC power to the R and C terminals on the controller.
This connection provides power to the microprocessor and display of
the controller.
2. When wiring an optional sensor to the SetPoint 501s, connect the two
wires from the sensor to the Com and S1 terminals.
Note: The Heat terminals are isolated outputs. There is no power available
on these terminals from the controller. Use these terminals as a
switch for a 24VAC circuit. This circuit can operate a low-current,
24VAC device directly or an external relay to enable a line-voltage
or high-current device.
Installing the Front Cover
1. Align the hinges on the bottom of the front
cover with the bottom of the controller
mounting base.
2. Pivot the front cover around the bottom
hinges and push the top against the
mounting base until it snaps firmly in place.
(See Figure 3.)
Wiring Examples for the SetPoint 501 and SetPoint 501s
Refer to the figures below to wire 24VAC power and the optional sensor.

Optional Sensors (501s Only)
Each controller has a single built-in sensor to measure air temperature.
In addition to this built-in sensor, the SetPoint 501s features terminals to
connect one additional sensor (i.e., indoor sensor, outdoor sensor, slab or
floor sensor or sensor placed in a remote location).
Indoor Sensor
An indoor sensor measures the air temperature in the zone that the
SetPoint is controlling. The temperature measured by the outdoor sensor
is used in the on-time calculations for the relay in the controller. Select this
setting on the Adjust menu. If the built-in sensor is on and the auxiliary
sensor is set to Indoor, the temperatures of the sensors are averaged and
used to calculate the on time of the relay.
Outdoor Sensor
An outdoor sensor measures the temperature of the air outside. The
temperature measured by the outdoor sensor does not affect the on time
of the relay and is only used for display purposes.
Slab or Floor Sensor
A slab or floor sensor measures the slab or floor temperature in the zone
that the controller is controlling. The temperature the slab or floor sensor
reads is used in the on-time calculations for the Heat relay and allows the
controller to operate the slab between the minimum and maximum
slab settings.
Access Levels (501s Only)
The SetPoint 501s features two access levels —
User and Installer — which restrict the number
of items available in the display menus. Change
the access level via the DIP switch located on
the circuit board inside the controller. (See
Figure 9.)
The Installer access level allows the installer to
adjust all the settings in the controller including
those required to match the controller to the
mechanical system and devices. The User access
level allows the end user to adjust the
temperature settings.

Section 2 — Installation
Display and Keypad Operation
The SetPoint 501 and 501s Controllers feature four fields: Menu, Item,
Number and Status. (See Figure 7.)
Cycles per Hour
The SetPoint 501 and 501s controllers operate on cycles per hour. The
number of cycles per hour is adjustable through the Heat Cycle setting in
the Adjust menu. During each cycle that heating is required, the controller
turns on the Heat relay for a calculated amount of time. This amount of time
is called the on time. The on time is calculated based on the requirements
of the zone. If the zone requires more heating, the appropriate on time is
increased. If the zone requires less
heating, the appropriate on time is
reduced. (See Figure 8.)
The controller ensures the relay
remains on or off for a minimum
amount of time to prevent
short cycling.
An Auto Cycle setting is available for the heating cycle. This setting
determines the optimum number of cycles per hour to balance temperature
swings and equipment cycles.

Sequence of Operation
Air Sensor Only Operation
When operating with only an air sensor, the on time for the Heat relay is
calculated to satisfy the requirements of the air sensor.
Slab or Floor Sensor Only Operation (501s Only)
When operating with only a slab or floor sensor, the on time for the Heat
relay is calculated to satisfy the requirements of the slab or floor sensor.
The controller operates to maintain the slab at the minimum slab
temperature setting.
Note: Using only a slab or floor sensor may cause overheating or
underheating of the space.
Air and Slab or Floor Sensor Operation (501s Only)
When operating with both air and slab or floor sensors, the controller
calculates an on time for the Heat relay to satisfy the slab or floor sensor’s
requirements and an on time to satisfy the air sensor’s requirements. The
Heat relay operates for the longer of these two on times.
During light heating loads, overheating can occur due to the minimum slab
or floor temperature requirements.
During heavy heating loads, the maximum slab or floor temperature
setting limits the on time of the Heat relay. In this situation, underheating
can occur.
Mode
Heat
In the heat mode, the Heat relay satisfies the temperature requirement of
the zone.
Off
The Heat relay does not operate in the Off mode.
Note: If an air, slab or floor sensor is active in the Off mode, a freeze-
protection function enables, allowing the Heat relay to operate
and keep the zone above 35°F (2°C).
