Tekmar 444 Mixing Expansion Module, Variable Speed, Floating Action, Modulating.

This Tekmar 444 Mixing Expansion Module is designed to operate a mixing device within a hydronic heating system as part of a tekmarNet® control system. It is capable of controlling a mixed system pump and six optional outputs for mixing: a variable speed injection pump, a floating action actuator, or an analog 0-10 V (dc), 2-10 V (dc), 0-20 mA, or 4-20 mA signal.

Product Features:

  • Powered variable speed injection pump
  • Analog 0-10 V (dc) or 2-10 V (dc) output
  • Powered 24 V (ac) system pump output
  • Powered 24 V (ac) floating action output
  • CSA C US certified for use in USA and Canada
  • Powered 120 V (ac) system pump
  • Requires a tekmarNet® 4 system control
  • Analog 0-20 mA or 4-20 mA output
  • SKU: Tekmar 444
