Mixing Control 362e

The Mixing Control 362e is a microprocessor based control designed to provide a reset mixed supply water temperature to

a heating system based on outdoor air temperature. Multiple zone temperature control can be achieved by using either a

conventional thermostat system or by using kanmor Zone Controls attached to the 362e. For single zone heating applications, a

single Room Temperature Unit (RTU) can be connected directly to the 362e for zone temperature control.

The 362e incorporates a large Liquid Crystal Display (LCD) in order to provide system status and operating information. The

same LCD is used when setting up and installing the control. Standard features include boiler return protection, intelligent boiler

operation, Warm Weather Shut Down (WWSD), and pump exercising. As well, with the addition of a new Monitor feature, it is now

possible to track pump and boiler running hours, boiler cycles and high and low sensor temperatures.

The 362e uses a floating action output signal to control the position of a mixing valve.

Summary of Contents for Kanmor Mixing Control 362e

Page 1 Mixing Control 362e 06/03 The Mixing Control 362e is a microprocessor based control designed to provide a reset mixed supply water temperature to a heating system based on outdoor air temperature. Multiple zone temperature control can be achieved by using either a conventional thermostat system or by using kanmor Zone Controls attached to the 362e.

How To Use The Data Brochure This brochure is organized into four main sections. They are: 1) Sequence of Operation, 2) Installation, 3) Control Settings, and 4) Troubleshooting. The Sequence of Operation section has three sub sections. We recommend reading Section A: General Operation, as this contains important information on the overall operation of the control.

Page 4: Sequence Of Operation
POWERING UP THE CONTROL When the Mixing Control 362e 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 and the LCD defaults to displaying the current outdoor air temperature.
Page 5: Section B: Mixing Reset
Section B: Mixing Reset Section B1 Section B2 General Alternate Mixing Mixing Operation Demand Section B1: General Mixing Operation MIXING DEMAND A mixing demand is generated by applying a voltage between 24 and 230 V (ac) across the Mix Demand terminals (1 and 2). Once voltage is applied, the Mix Demand pointer is displayed in the LCD.
Page 6 MIXING TARGET TEMPERATURE (MIX TRG) The MIX TRG temperature is determined from the Characterized Heating Curve settings and the outdoor air temperature. The control displays the temperature that it is currently trying to maintain as the mixing supply temperature. If the control does not presently have a requirement for heat, it displays “–...
Page 7 10K INDOOR SENSOR (10K = INDR) Set the 10K item to INDR to add an indoor sensor for temperature Indoor kanmor control of a single zone mixing system. The indoor sensor is Sensor 362e Control connected to the Com and 10K terminals (12 and 13).
Page 8 Set the 10K item to ZoIn to add indoor temperature feedback control of multiple mixing zones. Control of mixing zones is provided by connecting a kanmor zone control to the control. The zone control provides its own internal mixing demand to the control. In this case, there is no need to provide an external Mix Demand as described earlier in Section B1.

Section C: Boiler Operation Section C1 Section C2 Section C3 Boiler Supply Boiler Return No Boiler Sensor Sensor Sensor Section C1: Boiler Supply Sensor BOILER SENSOR ON THE SUPPLY (Boil SENS = SUP) The boiler sensor can be located on the boiler supply if the 362e is the only control that is operating the boiler.
Page 10 BOILER FIRE DELAY (Boil DLY) The Boil DLY is the delay time that may happen between the time that the control closes the boiler contact and the burner fires. This delay is usually the result of a burner pre-purge or other forms of time delay built into the burner’s safety circuits. BOILER MASS (Boil MASS) The Boil MASS setting allows the control to adjust to different types of heat sources depending on their thermal mass.

If a Remote Display Module (RDM) 040e is used, install the RDM according to the installation instructions in Data Brochure D 040e and run the wiring back to the control. • If a kanmor Zone Control is used, run the wires from the Zone Control to the 362e. Refer to the instructions supplied with the Zone Control. •...
Page 13 Zone Control Zone Control Input If an external kanmor Zone Control is used, connect the wire from the Com Sen terminal on the Zone Control to the Com terminal (12) on the 362e. Connect the Zo Out terminal on the Zone Control to the 10K terminal (13) on the 362e.
Page 14: Testing The Wiring
UnOccupied Switch If an external timer or switch is used, connect the two wires from the external switch to the Com and UnO Sw terminals (12 and 14). When these two terminals are shorted together, the control registers an UnOccupied signal. Note: The setback override in the schedule menu of the control overrides any external signal that is present on the UnOccupied Switch terminals.
Page 15 Boiler If the boiler is connected to the Boiler terminals (6 and 7), make sure power to the boiler circuit is off and install a jumper between the terminals. When the boiler circuit is powered up, the boiler should fire. If the boiler does not turn on, refer to any installation or troubleshooting information supplied with the boiler.

MAX HEAT (MAX HEAT) The Mixing Control 362e has a function called MAX Heat. In this mode, the control turns on and operates the system up to the maximum set temperatures, and the mixing device at the set percentage, as long as there is a demand for heat. The control continues to operate in this mode for up to 24 hours or until either the Item, Menu or Test button is pressed.
Page 24 Troubleshooting When troubleshooting any heating system, it is always a good idea to establish a set routine to follow. By following a consistent routine, many hours of potential headaches can be avoided. Below is an example of a sequence that can be used when diagnosing or troubleshooting problems in a hydronic heating system.
