Powering Up The Control
When the HeatLink®Mixing Valve Reset Control Stk# 31360 is powered up, the control displays the control type number in the LCD for 2 seconds.
Next, the software version is displayed for 2 seconds. Finally, the control enters into the normal operating mode.
Operation
The Stk# 31360 uses a floating action mixing valve to vary the supply water temperature to a hydronic system. The supply water temperature is
based on either the current outdoor temperature, or a xed setpoint.
Outdoor Reset (North American version)
The amount of heat lost by a building changes depending on the outdoor air temperature. The
amount of heat supplied by the heating system must be equal to the amount of heat being lost
in the building. If the amount of heat supplied is not equal, the building will either overheat
or cool off.
When the Outdoor Design setting is set to a temperature, the control calculates a mix supply
temperature based on the outdoor air temperature and the programmed reset ratio.
Setpoint Control
When the outdoor design (OUTDR DSGN) setting is set to OFF, the Stk# 31360 supplies a xed mixing supply temperature equal to the MIX
TARGET setting. An outdoor sensor is not required during this mode of operation.

General Operation
Exercising
The Stk# 31360 has a built-in exercising function. If the system pump or valve has not been operated at least once every 3 days, the control turns
on the output for a minimum of 10 seconds. This minimizes the possibility of a pump or valve seizing during a long period of inactivity. The
Stk# 31360 ensures that the mixing valve operates over its entire range at least once each exercising period. While the control is exercising, the
Test LED flashes.
Note: The exercising function does not work if power to the control, pump, or valve is disconnected.
Setback (OCC and UNOCC)
To provide greater energy savings, the Stk# 31360 has a setback capability. With setback, the supply water
temperature in the system is reduced when the building is unoccupied. By reducing the supply water
temperature, air temperature in the space may be reduced even when thermostat(s) are not turned down.
Any time the UnO Sw (12) and the Com (13) terminals are shorted together, the control operates in the
unoccupied (Night) mode. When in the unoccupied (Night) mode, the UNOCC segment is displayed in
the LCD. The Stk# 31360 adjusts the supply water temperature based on the UNOCC settings made in the
control. This feature has no effect when the control is used as a setpoint control.
Warm Weather Shut Down (WWSD) OCC & UNOCC
When the outdoor air temperature rises above the Warm Weather Shut Down (WWSD) setting, the control turns on the WWSD segment in the
display. When the control is in WWSD, the Mix Demand pointer is displayed if there is a demand. However, the control does not operate the heating
system to satisfy this demand. If the control is in setpoint mode, the WWSD feature is not functional.

Floating Action
A 24 V (ac) floating action actuator motor is connected directly to the Stk# 31360 on the R Opn, R Cls and C terminals (9, 10 and 11). The Stk# 31360
pulses the actuator motor open or close to maintain the correct mixed supply water temperature at the mix sensor when there is a mixing demand.
The mixing valve that the actuator is connected to can be either a 2-way, 3-way, or 4-way valve. A visual indication as to whether the control is
currently opening or closing the mixing valve is displayed in the LCD.

Boiler Protection (Boil Min)
The Stk# 31360 is capable of providing boiler protection from cold mixing system return
water temperatures. If the boiler sensor temperature is cooler than the BOIL MIN setting
while the boiler is ring, the Stk# 31360 reduces the output to the mixing valve. This
limits the amount of cool return water to the boiler and allows the boiler temperature
to recover. This feature can only be used if a boiler sensor is installed.
Factory Defaults
The control comes preset with several factory defaults. To ne-tune building requirements, these defaults may be changed. If a factory default value
for a terminal unit is changed, the terminal unit number will flash when selected in the ADJUST menu. For the European version, these defaults
are based on the terminal unit selection page 9.
To reload the factory defaults power down the control and wait for 10 seconds. Power up the control while simultaneously holding the Item and
buttons. The terminal unit number should now be displayed constantly in the LCD rather than flashing.

Mixing Operation
System Pump Operation (Sys Pmp)
The system pump contact (Sys Pmp, terminal 5) closes whenever there is a mixing demand and the Stk# 31360 is not in WWSD. The system
pump segment is displayed in the LCD. After the mixing demand has been satised, the Stk# 31360 continues to operate the system pump for 20
seconds. This allows some residual heat to be purged out to the heating system. During WWSD, the system pump is operated based on the exercise
function.
Mixing Demand
A mixing demand is required in order for the Stk# 31360 to provide heat. A mixing demand is
generated by applying a voltage between 24 and 240 V (ac) across the Mixing Demand terminals
(1 and 2). Once voltage is applied, the Mixing Demand pointer is displayed in the LCD. If the
Stk# 31360 is not in WWSD, the Stk# 31360 closes the Sys Pmp contact. The Stk# 31360 calculates
a MIX TARGET supply temperature based on the outdoor air temperature and settings. If required,
the Stk# 31360 operates the boiler in order to provide heat to the mixing valve.

Reset Ratio
The reset ratio requires two points to establish the rate at which the mix supply water temperature
is to be increased for every degree that the outdoor air temperature falls. The starting point of the
reset ratio is xed at 70˚F (21˚C). The end point can be changed using the OUTDOOR DESIGN
and the MIX DESIGN settings.
Outdoor Design (OUTDR DSGN)
The OUTDR DSGN is the outdoor air temperature that is the typical coldest temperature of the year where the building is located. This temperature
is used when doing heat loss calculations for the building. If a cold outdoor design temperature is selected, the mix supply temperature rises
gradually as the outdoor temperature drops. If a warm outdoor design temperature is selected, the mix supply temperature rise rapidly as the
outdoor temperature drops.
Mix Design (MIX DSGN)
The MIX DSGN temperature is the supply water temperature required to heat the mixing zones when the outdoor air is as cold as the OUTDR
DSGN temperature.
Room Occ & Unocc (ROOM)
The Room setting is the desired room temperature for the mixing zones, and it provides a parallel
shift of the Reset Ratio. If the room temperature is not correct, adjusting the Room setting increases
or decreases the amount of heat available to the building. A Room setting is available for both the
occupied and unoccupied modes.
Mix Maximum (MIX MAX)
The MIX MAX sets the highest water temperature that the control is allowed to calculate as the MIX TARGET temperature. If the control does
target the MIX MAX setting, and the MIX temperature is near the MIX MAX, the MAX segment will be displayed in the LCD while either the
MIX TARGET temperature or the MIX temperature is being viewed.

Mix Minimum (MIX MIN)
The MIX MIN is the lowest temperature that the control is allowed to use as a MIX TARGET temperature. During mild conditions, if the Stk#
31360 calculates a MIX TARGET temperature that is below the MIX MIN setting, the MIX TARGET temperature is adjusted to match the MIX
MIN setting. During this condition, the MIN segment will be displayed in the LCD when either the MIX TARGET or MIX temperature is being
viewed.
Mix Target Temperature (MIX TARGET)
When used as a mixing reset control, the MIX TARGET temperature is calculated from the
Reset Ratio settings and the outdoor air temperature. When used as a setpoint control, the
installer sets the MIX TARGET temperature. The control displays the temperature that it
is currently trying to maintain as the mix supply temperature. If the control does not have
a mix demand, “- - -” is displayed as the MIX TARGET in the VIEW menu.
Setpoint Operation (MIX TARGET)
For setpoint operation, set the OUTDR DSGN to OFF. The MIX TARGET becomes the setpoint supply temperature that the control is to maintain.
The MIX TARGET temperature is set by the installer in the ADJUST menu. An outdoor sensor is not required during this mode of operation.

Characterized Heating Curve
The characterized Heating Curve takes into account the type of terminal unit that the system is using. Since different types of terminal units transfer
heat to a space using different proportions of radiation, convection and conduction, the supply water temperature must be controlled differently.
Once the control is told what type of terminal unit is used, the control varies the supply water temperature according to the type of terminal unit.
This improves the control of the air temperature in the building.
Outdoor Design (OUTDR DSGN)
The OUTDR DSGN is the outdoor air temperature that is the typical coldest temperature of the
year where the building is located. This temperature is used when doing the heat loss calculations
for the building. If a cold outdoor design temperature is selected, the mixing supply temperature
rises gradually as the outdoor temperature drops. If a warm outdoor design temperature is selected,
the mixing supply temperature rises rapidly as the outdoor temperature drops.

Mixing Target Temperature (MIX TARGET)
When used as a mixing reset control, The MIX TARGET temperature is calculated from the Characterized Heating Curve settings, outdoor air
temperature and optionally, indoor air temperature. When used as a setpoint control, the installer sets the MIX TARGET temperature. The control
displays the temperature that it is currently trying to maintain as the mixing supply temperature. If the control does not have a mixing demand,
“- - -” is displayed as the MIX TARGET.
System Pump Operation (Sys Pmp)
The system pump contact (Sys Pmp, terminal 5) closes whenever there is a mixing demand and the
Stk# 31360 is not in WWSD. The system pump segment is displayed in the LCD. After the mixing
demand has been satised, the Stk# 31360 continues to operate the system pump for 20 seconds. This allows some residual heat to be purged out
to the heating system. During WWSD, the system pump is operated based on the exercise function.
Indoor Sensor
An indoor sensor may be used in order to provide indoor temperature feedback. The indoor sensor is connected to the Com and Indr terminals (16
and 18). In addition, power must be applied to the Mixing Demand terminals (1 and 2) as described in the MIXING DEMAND section. With the
indoor sensor connected, the Stk# 31360 is able to sense the actual room temperature. Indoor temperature feedback ne-tunes the supply water
temperature in the mixing system to maintain room temperature. To adjust the room temperature, use the ROOM OCC or ROOM UNOCC setting
in the ADJUST menu at the control. Feedback ne-tunes the supply water temperature in the mixing system to maintain room temperature. To
adjust the room temperature, use the ROOM OCC or ROOM UNOCC setting in the ADJUST menu at the control.
If a multiple zone system is used with an indoor sensor, proper placement of the indoor sensor is essential. The indoor sensor should be located in
an area which best represents the average air temperature of the zones.
Mixing Demand
A mixing demand is required in order for the Stk# 31360 to provide heat. A mixing demand is
generated by applying a voltage of 24 V (ac) or 24 V (dc) across the Mixing Demand terminals
(1 and 2). Once voltage is applied, the Mixing Demand pointer is displayed in the LCD. If the
Stk# 31360 is not in WWSD, the Stk# 31360 closes the Sys Pmp contact. The Stk# 31360 calculates
a MIX TARGET supply temperature based on the outdoor air temperature and settings. If required,
the Stk# 31360 operates the boiler in order to provide heat to the mixing valve.

Terminal Units
When using a Characterized Heating Curve, the control requires the selection of a terminal unit. The terminal unit determines the shape of the
Characterized Heating Curve according to how the terminal unit delivers heat into the building space. The Stk# 31360 provides for selection
between six different terminal unit types: two types of radiant oor heat, fancoil, n-tube convector, radiator and baseboard. When a terminal unit
is selected, the control automatically loads the design supply temperature (MIX DSGN), maximum supply temperature (MIX MAX) and minimum
supply temperature (MIX MIN). The factory defaults are listed below. To change defaults, refer to Advanced Mixing Pg. 10; If a default has been
changed, refer to Pg. 5 to reload the factory defaults.
High Mass Radiant (1)
This type of a hydronic radiant floor is embedded in either a thick concrete or gypsum pour. This heating
system has a large thermal mass and is slow acting.
Default values: MIX DSGN = 120 °F (49°C), MIX MAX = 140 °F (60°C), MIX MIN = OFF
Low Mass Radiant (2)
This type of radiant heating system is either attached to the bottom of a wood sub-floor, suspended in the
joist space, or sandwiched between the sub-floor and the surface. This type of radiant system has a relatively
low thermal mass and responds faster than a high mass system.
Default values: MIX DSGN = 140 °F (60°C), MIX MAX = 160 °F (71°C), MIX MIN = OFF
Fancoil (3)
A fancoil terminal unit or air handling unit (AHU) consists of a hydronic heating coil and either a fan or
blower. Air is forced across the coil at a constant velocity by the fan or either a fan or blower. Air is forced
across the coil at a constant velocity by the fan or blower, and is then delivered into the building space.
Default values: MIX DSGN = 190°F (88 °C), MIX MAX = 210°F (99°C), MIX MIN = 100°F (38°C)
Fin–tube Convector (4)
A convector terminal unit is made up of a heating element with ns on it. This type of terminal unit relies
on the natural convection of air across the heating element to deliver heated air into the space. The amount
of natural convection to the space is dependant on the supply water temperature to the heating element and
the room air temperature.
Default values: MIX DSGN = 180 °F (82°C), MIX MAX = 200 °F (93°C), MIX MIN = OFF

For setpoint control, set the OUTDR DSGN to OFF. The MIX TARGET becomes the setpoint
supply temperature that the control is to maintain. The MIX TARGET temperature is set by
the installer in the ADJUST menu. An outdoor sensor is not required during this mode of
operation.
Room OCC & UNOCC (ROOM)
The ROOM is the desired room temperature for the mixing zones, and it provides a parallel shift
of the Characterized Heating Curve. The room temperature desired by the occupants is often
different from the design indoor temperature (MIX INDR). If the room temperature is not correct,
adjusting the ROOM setting increases or decreases the amount of heat available to the building.
A ROOM setting is available for both the occupied (Day) and unoccupied (Night) modes.

Mixing Maximum (MIX MAX)
The MIX MAX sets the highest water temperature that the control is allowed to calculate as the MIX TARGET temperature. If the control does
target the MIX MAX setting, and the MIX temperature is near the MIX MAX, the MAX segment will be displayed in the LCD while either the
MIX TARGET temperature or the MIX temperature is being viewed.
Mixing Design (MIX DSGN)
The MIX DSGN temperature is the supply water temperature required to heat the mixing zones when the outdoor air is as cold as the OUTDR
DSGN temperature.
Mixing Minimum (MIX MIN)
The MIX MIN is the lowest temperature that the control is allowed to use as a
MIX TARGET temperature. During mild conditions, if the Stk# 31360 calculates a
MIX TARGET temperature that is below the MIX MIN setting, the MIX TARGET
temperature is adjusted to match the MIX MIN setting. During this condition, the
MIN segment will be displayed in the LCD when either the MIX TARGET or
MIX temperature is being viewed. If an indoor sensor is used, and the Stk# 31360
is operating at the MIX MIN temperature, the system pump is cycled using Pulse
Width Modulation (PWM) with a 15 minute cycle length. By cycling the system
pump and controlling the flow of supply water, the control provides an average
supply water temperature to the system. This average temperature is equal to the
original MIX TARGET. This minimizes overheating of the zone while the control
is operating at the MIX MIN temperature.
Warm Weather Shut Down (WWSD) OCC & UNOCC
When the outdoor air temperature rises above the WWSD setting, the When the
outdoor air temperature rises above the WWSD setting, the Stk# 31360 turns on
the WWSD segment in the display. When the control is in Warm Weather Shut
Down, the Mixing Demand pointer is displayed, if there is a demand. However, the
control does not operate the heating system to satisfy this demand. If the control
is in setpoint mode, the WWSD feature is not functional.

Characterized Heating Curve for the mixing zones.
Radiator (5)
A radiator terminal unit has a large heated surface that is exposed to the room. A radiator provides heat to
the room through radiant heat transfer and natural convection.
Default values: MIX DSGN = 160 °F (71°C), MIX MAX = 180 °F (82°C), MIX MIN = OFF
Baseboard (6)
A baseboard terminal unit is similar to a radiator, but has a low prole and is installed at the base of the
wall. The proportion of heat transferred by radiation from a baseboard is greater than that from a n-tube
convector.
Default values: MIX DSGN = 150 °F (66°C), MIX MAX = 170 °F (77°C), MIX MIN = OFF

Boiler Operation
Boiler Return Sensor
The boiler return sensor, if used, should be located on the boiler return and enables the boiler to operate at the
operating aquastat setting as described in the BOILER ENABLE section.
Boiler return
sensor
No Boiler Sensor
The 31360 is capable of operating without a boiler return sensor if desired. Without a boiler return sensor, the 31360
provides a boiler enable as described in the BOILER ENABLE section, but is unable to provide boiler protection.
This type of application is typical if the 31360 is drawing heat from a heat source that already incorporates some
form of boiler protection.
No boiler
sensor
Boiler Enable
The Boiler Enable contact allows the boiler to ignite and operate at the boiler's operator setting.
The control closes the Boiler Enable contact when the position of the mixing valve exceeds 30%. The Boiler Enable contact remains closed until
the position of the mixing valve reduces below 15%.
In order to prevent short cycling, the Boiler Enable contact has a minimum on time, and a minimum off time.
Boiler Minimum (BOIL MIN)
Most boilers require a minimum water temperature in order to prevent flue gas condensation. Check the boiler data brochure's minimum recommended
operating temperature and set the BOIL MIN. Only when a boiler return sensor measures the boiler temperature can the control provide boiler
protection. In this case, when the boiler is ring and the boiler return temperature is below the Boil Min setting, the control turns on the MIN
segment and reduces the heating load on the boiler by limiting the output of the mixing valve. If the installed boiler is designed for low temperature
operation, set the BOIL MIN adjustment to OFF.

Boiler Operation (European Version)
Boiler Sensor on the Supply (Boiler Sensor DIP switch = Supply)
The boiler sensor can be located on the boiler supply if the Stk# 31360 is the only control that is operating the boiler.
When in the supply mode, the Stk# 31360 determines the required operating temperature of the boiler using Boiler
Load Reset. With Boiler Load Reset, the Stk# 31360 operates the boiler at the lowest possible supply temperature
that is sufcient to satisfy the requirements of the mixing valve. If this mode of operation is selected, the boiler pump
should either operate continuously, or be operated in parallel with the system pump contact (Sys Pmp).
Note: The boiler pump should not be operated by the boiler’s aquastat, as this may lead
to improper cycling of the boiler because of inconsistent flow past the boiler supply sensor.
Boiler supply
sensor
Boiler Differential (BOIL DIFF)
An on / off heat source such as a boiler must be operated with a differential in
order to prevent short cycling. When the boiler supply temperature drops below
the bottom rail of the differential, the Stk# 31360 closes the Boiler contact to
re the boiler. When the boiler supply temperature rises above the top rail of
the differential, the Stk# 31360 opens the Boiler contact to turn off the boiler.
With the Stk# 31360, either a xed or automatic differential setting is selected. If
automatic differential (Ad) is selected, the Stk# 31360 automatically adjusts the
boiler differential under the current load conditions to avoid short cycling.

Boiler Sensor on the Return (Boiler Sensor DIP switch = Return)
The boiler sensor should be located on the boiler return if the Stk# 31360 is one of many controls that can call for
boiler operation. When in the return mode, the Stk# 31360 provides a boiler enable as described in the BOILER
ENABLE section. The Stk# 31360 no longer tries to control the boiler supply water temperature directly but allows
the boiler to operate at its operating aquastat setting when required. If this mode of operation is selected, the boiler
pump should either operate continuously, or be operated in parallel with the system pump contact (Sys Pmp).
Note: The boiler pump should not be operated by the boiler’s aquastat, as this may lead to improper cycling
of the boiler because of inconsistent flow past the boiler return sensor.

This type of application is typical if the Stk# 31360 is drawing heat from a heat source that already incorporates
some form of boiler protection.
No boiler
sensor
Boiler Enable (30% Enable / 10% Enable)
The Stk# 31360 has a DIP switch that allows for the selection between a 30% boiler enable and a 10% boiler enable. This switch is only functional
when the Boiler Sensor DIP switch is set to Return.
In the 30% position, the Stk# 31360 closes the Boiler contact when the position of the mixing valve exceeds 30%. The Boiler contact remains
closed until the position of the mixing valve reduces below 15%. This setting would normally be chosen for low mass boilers (copper n-tube,
etc.), or systems with low thermal mass in the loop between the boiler and the mixing valve.
In the 10% position, the Stk# 31360 closes the Boiler contact when the position of the mixing valve exceeds 10%. The Boiler contact remains
closed until the position of the mixing valve reduces below 5%. This setting is normally chosen for high mass boilers (cast iron, steel re-tube,
etc.), or systems with large thermal mass in the loop between the boiler and the mixing valve. In order to prevent short cycling, the Boiler contact
has a minimum on time, and a minimum off time.
Refer to Page 4 for a description of boiler protection.
When the Stk# 31360 determines that boiler operation is required, the Boiler contact terminals (7 and 8) close. While the Boiler contact is closed,
the burner segment in the LCD is displayed.
Boiler Minimum (BOIL MIN)
Most boilers require a minimum water temperature in order to prevent flue gas condensation. The BOIL MIN adjustment is set to the boiler
manufacturer’s minimum recommended operating temperature. Only when the boiler temperature is measured by a boiler sensor can the Stk#
31360 provide boiler protection. In this case, when the boiler is ring and the boiler temperature is below the BOIL MIN setting, the Stk# 31360
turns on the MIN segment and reduces the heating load on the boiler by limiting the output of the mixing valve. If the installed boiler is designed
for low temperature operation, set the BOIL MIN adjustment to OFF.

If a oating action actuating motor circuit is connected to the R Opn, R Cls and C terminals (9, 10 and 11), the control’s Test Sequence can be
used to check the motor circuit. Once the Test button is pressed, the valve should move to the fully open position. If the motor closes instead of
opening, the wiring of the actuating motor must be reversed. Next, the valve should move to the fully closed position. If it does not, check the
wiring between the terminals and the actuating motor. Refer to any installation or troubleshooting information supplied with the motor.
Connecting The Control
Important: Make sure all power to the devices and terminal blocks is off,
and remove any remaining jumpers from the terminals.
Reconnect the terminal blocks to the control by carefully aligning them with their respective
headers on the control, and then pushing the terminal blocks into the headers. The terminal blocks
should snap rmly into place.
Install the supplied safety dividers between the unpowered sensor inputs and the powered 120
