Hot Water Heating/Hydronics - Two Temperature Requirement

Where you have an Electro-Boiler requirement with a high temperature zone combined with low temperature radiant floor, Electro Industries now has a special controller which can be added to the TS Series boilers.

  • Handled as the priority zone on multi-zone or multi-pump controllers
  • Priority switch on, zone 1 active - TS boiler automatically changes to 150° (or selection 176°) supply water setting
  • All other zones are held off
  • With zone 1 satisfied or 60-minute timeout, the boiler automatically returns to the preset temperature and reacts to the other zones
