I would recommend using http://www.supplyhouse.com/Tekmar-274-Boiler-Control-One-tN4-Four-Stage-Boiler-DHW-Setpoint-9955000-p to replace the 362
This control has the option of using a boiler sensor. If the boiler sensor is on the boiler return and the boiler return temperature measured by the sensor is at or below the boiler min setting then the injection is ramped down to allow the boiler loop to heat back up, thus providing boiler return protection to the boiler.
Yes, the 356 is the direct cross reference of the 353.
If you are doing variable speed mixing with a circulator, you need the 356 control. If you are using a modulating mixing valve, you need the 360 control.
