CONTROL OVERVIEW
The Wirsbo proMIX 101 is a weather responsive,
single temperature reset control for hydronic
radiant heating systems. The proMIX 101 provides
either reset or setpoint supply water temperatures
through the use of a floating action mixing valve.
This control also protects the boiler from low return
water temperatures by monitoring the boiler return
water temperature. The proMIX 101 can function
as a standalone mixing control or function as an
expansion module to the Wirsbo SYSTEMpro 311.

INSTALLATION - STEP 3
ROUGH-IN WIRING
Things to note before you start wiring:
• All electrical wiring should end in the control base wiring
chamber
• The base has standard 7/8” (22 mm) knockouts
• Knockouts accept common wiring hardware and conduit
fittings
• Before removing knockouts, check wiring diagram and
select those sections of the chamber with common
voltages
• Do not allow the wiring to cross between low/high voltage
sections or else wires will interfere with safety dividers
(these dividers should be installed at a later time)
• Do not apply power to any of the wires during rough-in
wiring stage
• All wires should be stripped to 3/8"L (9 mm) for the correct
connection to the control
Wiring Components:
1) Install the various sensors indicated below as per instructions
listed and run the wiring back to the control base and label all
wires for later installation
Main Sensors: • Outdoor Sensor S4
• Boiler Return Sensor S3
• Mixing Sensor S1
2) Run appropriate wire from all other system components
(pump, boiler, etc.) to the control base
3) Run wires from the 120 VAC power to the control base
• Use a clean power source to ensure proper operation
• Comply with local codes for minimum gauge and breaker
requirements

INSTALLATION - STEP 5
MOUNTING THE SENSORS
Outdoor Sensor (S4) (See fig. a)
The Outdoor Sensor includes a 10 kΩthermistor which
provides an accurate measurement of the outdoor
temperature. The sensor is protected by a white U.V.
resistant PVC plastic enclosure.
Step One – Mounting (See fig. b)
NOTE: The temperature sensor (thermistor)
is built into the enclosure.
• Remove the screw and pull the front
cover off the sensor enclosure.
• The outdoor sensor can either be
mounted directly onto a wall or a 2" x 4"
electrical box. When the sensor is wall
mounted, the wiring should enter
through the back or bottom of the
enclosure. Do not mount the sensor with
the conduit knockout facing upwards as
rain could enter the enclosure and
damage the sensor.
• In order to prevent heat transmitted through the wall from
affecting the sensor reading, it may be necessary to install an
insulating barrier behind the enclosure.
• The outdoor sensor should be mounted on an exterior wall
which best represents actual outdoor temperature (a north
facing wall). It should not be exposed to heat sources such
as solar gain, exhaust ventilation or window openings.
• The outdoor sensor should be installed at an elevation
above the ground that will prevent accidental damage or
tampering. Installing the sensor in the shadow of the roof
eave is common.
Step Two – Wiring and Testing (See fig. c)
• Connect 18 AWG or similar wire to the two terminals provided
in the enclosure and run the wires from the outdoor sensor to
the control.
CAUTION: Do not run sensor wires parallel to
telephone or power cables. If the sensor wires
are located in an area with strong sources of
electromagnetic interference (EMI), shielded cable or
twisted pair should be used or the wires can be run
in a grounded metal conduit. If using shielded cable,
the shield wire should be connected to the Com Sen
terminal on the control and not to earth ground.
• Follow the sensor testing instructions in this brochure and
connect the wires to the control as per installation – step 6.
• Replace the front cover of the sensor enclosure.

Universal Sensors (S1 and S3)
(See fig. d)
These Universal Sensors have a zinc sleeve for fast response
and a wide operating range. They can be used in a multitude
of applications. They are supplied with 10 inches (250 mm) of
2 conductor wire.
Step One – Mounting (See figs. e thru g)
NOTE: The Sensor is designed to mount on
a pipe or in a temperature immersion well.
• The Universal Sensor can be strapped directly to the pipe
using the cable tie provided. Insulation should be placed
around the sensor to reduce the effect of air currents on the
sensor measurement.
• The Universal Sensor should be placed downstream of a
pump or after an elbow or similar fitting. Proper sensor
location requires that the fluid is thoroughly mixed within the
pipe before it reaches the sensor.
Step Two – Wiring and Testing
CAUTION: Do not run sensor wires parallel to
telephone or power cables. If the sensor wires
are located in an area with strong sources of
electromagnetic interference (EMI), shielded cable or
twisted pair should be used or the wires can be run
in a grounded metal conduit. If using shielded cable,
the shield wire should be connected to the Com Sen
terminal on the control and not to earth ground.
• If it is necessary to connect 18 AWG wire to the two sensor
wires, wire nuts can be used to hold the wires together.
• Follow the sensor testing instructions given in this brochure,
and then connect the wires to the control.

ELECTRICAL CONNECTIONS
TO THE CONTROL
IMPORTANT: Test to be certain
no voltage is present in any wires.
120 VAC Power (See fig. a)
• Connect 120 VAC power supply to Power L and neutral N
terminals (3 and 4)
• Provides power to microprocessor and control display as well
as power to Mix P1 terminal (5) from Power L terminal (3)
Demand Connections
Demand to the control is generated from a thermostat zone
control module or external relay. This connection must have
24 VAC supplied to the demand terminals.
Mixing Demand (See fig. b)
• Apply a voltage between 24 VAC and 240 VAC across Mixing
Demand terminals (1 and 2)
Mixing Demand with Wirsbo Thermostat
NOTE: When connecting a Wirsbo Thermostat WT1
or WT2 directly to the Mix Demand Terminals 1 and 2,
a 0.5 watt 1000 ohm resistor needs to be installed
parallel as shown. A packet with the resistor and
schematic is included in the box.

1) Boiler Contact (See fig. c)
Boiler terminals (7 and 8) are an isolated output. No power is
available on these terminals from the control.
• Use terminals as switch to make or break the boiler circuit
• When the proMIX 101 requires the boiler to fire, contact
closes between terminals 7 and 8
2) Mixing System Pump (Mix P1) (See fig. d)
Mixing System Pump (Mix P1) output terminals (5 and 6) are
powered outputs. When relay in the control closes, 120 VAC is
provided to Mix P1 terminal (5) from Power L and neutral
terminal (6). To operate the System Pump:
• Connect one side of system pump circuit to terminal (5)
• Connect the second side of pump circuit to neutral (N)
terminal (6)
4) Floating Action Mixing Valve (R Opn/R Cls/C)
(See fig. e)
The proMIX 101 utilizes a floating action mixing valve
to control the mixing system water temperature. Terminals
(9, 10 & 11) are powered 24 VAC from the control. There is no
need to provide a separate power source for the mixing valve
actuator.
• Connect to “Opn” (open) terminal from the mixing valve
actuator to the R Opn terminal (9) on the control
• Connect to “Cls” (close) terminal from the mixing valve
actuator to the R Cls terminal (10) on the control
