Appendix: Low Return Water Temperatures (continued)
Primary-Secondary Pumping:
Best Alternative: System by-pass kit [part number 107795-01] that addresses these situations.
A strap on temperature sensor measures boiler inlet temperatures. This temperature signal is sent to a variable
speed pump that will ensure boiler inlet temperatures are always greater than the factory by-pass kit set point of
120F.
Kit includes all fittings, pump, sensor and instructions.
This is an improvement over simple by-pass
piping to reduce condensation. Again this is a
fixed system. It can not adapt to variations in
temperature and flow.
