nergy efficiency is an important consideration when buying any heating system. But there are other fac-
tors you must consider too. Like manufacturer experience, reputation and service. The simple fact is, any
heating system is only as good as the company behind it.
Only the finest materials and craftsmanship is used to manufacture our products.
Operation
On call for heat the circulator comes on immediately, and the elements are energized in steps — two elements
per step spaced at approximately 60 second intervals. When the thermostat is satisfied, all elements and circu-
lator are de-energized at once. A high limit condition will instantly de-energize all elements and the circulator
will continue to run.
