Appendix: Low Return Water Temperatures (continued)
Primary-Secondary Pumping:
Kit includes all fittings, pump, sensor and
instructions for installation.
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.
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
120F.
