CLASSIC 800 Product Manual
Setup & Operation
1. View or Adjust Relay 1 & 2 Energized Mode
Both relays on the CLASSIC 800 have Normally Open and Normally Closed contacts. The terms ‘Open’ and
‘Closed’ refer to the de-energized state of the relays. Normally Open or Normally Closed operation for
Relay 1/
Relay 2
is determined by wiring the contacts accordingly (see Figures 11 & 12).
Note:
Low flow means less Thermal Signal as represented by the CLASSIC 800’s Thermal Signal Bar Graph.
Some configurations may require one or both relays to be energized on high flow, i.e. higher than the
set point.
