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.
