  • Page 2: Table Of Contents

    ® Mixing Valve Reset Control Stk# 31360 is designed to control the supply water temperature to a hydronic system in order to provide outdoor reset or setpoint operation. The control uses a floating action mixing valve to regulate the supply water temperature, while protecting the boiler against flue gas condensation.

  • Page 3: User Interface

    ® the LCD in order to set up and monitor the operation of your system. The Stk# 31360 has three push buttons (Item, “Up”, “Down”) for selecting, viewing, and adjusting settings. As you program your control, record your settings in the ADJUST menu table which is found in the second half of this brochure.

  • Page 4: General Operation

    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 fixed setpoint.
  • Page 5 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.

  • Page 6: Mixing Operation (North American Version)

    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 satisfied, the Stk# 31360 continues to operate the system pump for 20 seconds.
  • Page 7 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.

  • Page 8: Mixing Operation (European Version)

    Stk# 31360 is not in WWSD. The system pump segment is displayed in the LCD. After the mixing demand has been satisfied, 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.
  • Page 9 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 floor heat, fancoil, fin-tube convector, radiator and baseboard.
  • Page 10 MIN segment will be displayed in the LCD when either the MIX TARGET or (77) 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 (66) Width Modulation (PWM) with a 15 minute cycle length.

  • Page 11: Boiler Operation (North American Version)

    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.

  • Page 12: Boiler Operation (European Version)

    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.

  • Page 14 System Pump Contact (Sys Pmp) The Sys Pmp output terminal (5) on the Stk# 31360 is a powered output. When the relay in the Stk# 31360 closes, a120 V (ac) is provided to the SysPmp terminal (5) from the Power L terminal (3).

  • Page 15: Step Five - Testing The Wiring

    Indoor Sensor (European version only) If an indoor sensor is used, connect the two wires from the sensor to the Com and Indr terminals (16 and 18). The indoor sensor is used by the Stk# 31360 to measure the room air temperature. Unoccupied Switch If an external timer or switch is used to provide an unoccupied period, connect the two wires from the external switch to the UnO Sw and Com terminals (12 and 13).
  • Page 16 The boiler is controlled as described in Boiler Sensor Placement Page 12. For systems where the Stk# 31360 provides a heat demand to an external boiler control, the boiler sensor should be installed on the return side of the boiler loop. When the boiler sensor is installed on the return side of the boiler loop, the DIP switch must be set to Return. The Stk# 31360 enables the boiler when the position of the mixing valve exceeds the boiler enable DIP switch setting.
