Introduction
Introduction
Introduction
The Uponor Wirsbo SetPoint 150 Controller is a microprocessor-
based control that can be programmed to maintain a fixed
setpoint temperature by cycling a heating or cooling device.
This reliable and versatile controller features a wide setpoint
range and an adjustable differential and time delay for several
applications. A digital liquid crystal display (LCD) window shows
the actual setpoint and sensor temperatures as well as other
programmed settings. (See Figure 1.)
AUniversal Sensor (A3060071) is supplied with the SetPoint 150
Controller. The wire to the sensor can be extended up to 500 feet
(150m) with standard 18 AWG low-voltage wire. The display
indicates a sensor fault when the sensor is open or has a short
circuit.

Mounting the SetPoint 150 Controller
Follow the steps below to mount the controller.
1. Grasp the front cover by the fingertip grips on the top and
bottom of the enclosure and pull the front cover off.
2. Remove the wiring cover screw.
3. Use #6 screws to mount the enclosure flush onto a wall or
onto a 2x4 electrical box.
4. Wire the controller through the back or bottom of the
enclosure into the wiring chamber.
5. Reassemble the enclosure by first replacing the wiring
chamber cover and then pushing the front cover onto the
enclosure until it snaps into place.
Rough-in Wiring
All electrical wiring terminates in the two wiring chambers at the
bottom front of the controller.If the controller is mounted on an
electrical box, rough-in the wiring at the electrical box prior to
installing the controller. Uponor Wirsbo recommends standard
18 AWG solid wire for all low-voltage wiring to this controller.
Caution: Do not apply power to any of the wires during
this rough-in wiring stage.
1. Install the Universal Sensor and run the wiring back to the
controller,but do not connect it.
2. Install a 24VAC Class II transformer with a minimum 5 VA
rating close to the controller and run the wiring from the
transformer to the controller. A Class II transformer must
be used. Do not connect any of the transformer terminals
to the ground.
3. Install the wiring from the heating or cooling device control
circuit to the controller.

Installation
Connecting the Wiring
Caution: Only properly trained and experienced
technicians should perform these tests using standard
testing practices and procedures. A good quality
multimeter, capable of reading from at least 0 to
200VAC, and at least 0 to 2,000,000 Ohms, is essential
to properly test this controller. Ensure voltages in
excess of 28VAC are not present in any of the wires
connected to this controller.
Testing the Sensor
1. Measure the temperature using a thermometer, and then
measure the resistance of the sensor at the controller.
Note: Do not connect the wires from the sensor to the
controller while performing the test.
2. Using Table 4 below, estimate the temperature measured
by the sensor. The sensor and thermometer readings
should be close. If the multimeter reads a very high
resistance, this may indicate a broken wire, a poor wiring
connection or a defective sensor. If the resistance is very
low, this may indicate a wiring short, moisture in the
sensor or a defective sensor. To test for a defective sensor,
measure the resistance directly at the sensor location.
Testing the Power Supply
1. Ensure the wires from the power supply transformer are
not touching each other, any other wires or the ground.
2. Turn on the power and use an AC voltmeter to measure
between 20 and 28VAC at the secondary side of the
transformer.
3. Turn off the power and complete the electrical connections
to the terminal strip of the controller.

Power and Output Connections (See Figure 5.)
Caution: Maximum 24VAC
1. Connect the transformer to terminals 1 and 2 (C- and R+).
2. Connect the heating and cooling device circuit to the
appropriate terminals:
- Terminals 3 and 4 are normally open (N/O) and close
when the relay turns on.

Sequence of Operation
On/Off + Differential
Guidelines for programming the On/Off + Differential are stated
below. (See Figure 6.)
Differential: Setting the differential on any controller depends
entirely on the actual operating characteristics of the heating or
cooling equipment in each specific application. Set the differential
settings as small as possible for greatest accuracy, but take care
to avoid short cycling of the equipment. Experience, plus trial and
error during actual operating conditions, is typically the way most
installers determine the correct differential setting.
Delay: Setting the time delay also depends on the actual
operating characteristics of the heating or cooling equipment in a
specific application. With some equipment, time delays are
unnecessary and the delay setting can be set to zero. Other types
of equipment depend on a fixed off delay to prevent damage to
equipment components, particularly in the case of certain types
of refrigeration equipment. Consult the manufacturer's operating
and installation instructions for advice on recommended time
delays.
Sequence of Operation — On/Off Mode
When the controller is programmed for heat in this mode, the
relay is turned on and HEAT appears on the display when the
sensor temperature is half the differential setting below the
setpoint and the delay has timed out. When the sensor
temperature rises half the differential setting above the setpoint,
the relay turns off. HEATdisappears from the display,and the
delay starts to time out. During the time-out period, the Delay
pointer flashes if heating is needed. (See Figure 7.)
When the controller is programmed for cooling in this mode, the
relay is turned on and COOL appears on the display when the
sensor temperature is half the differential setting above the
setpoint and the delay has timed out. When the sensor
temperature drops half the differential setting below the setpoint,
the relay turns off. COOL disappears from the display, and the
delay starts to time out. During the time-out period, the Delay
pointer flashes if cooling is needed. (See Figure 8.)

Troubleshooting
Follow the Testing the Wiring procedure on page 4 ofthis manual
to troubleshoot the controller.
1. If Err displays, the sensor is open, has a short circuit or the
sensor temperature is outside the temperature range of the
controller. When this fault occurs, the controller turns off its
relay.
2. If the controller appears to be operating incorrectly, check
that the settings are correct and that the problem is not due
to external causes.
3. Ensure all wiring connections are connected properly and
the sensor is in the correct location.
Before Leaving
1. Install the wiring cover over the wiring chamber and secure
it with the screw provided.
2. Place the front cover on the controller to conceal the setting
dials and snap the cover into place.
3. Leave this manual in a conspicuous location near the
controller for future reference.
4. Explain the operation of this controller to the end user or
anyone else who will operate the system.
