Description

Features
  • Immersion-type controllers that combine high limit protection with low limit and circulator control in forced hydronic heating systems.
  • Provide multizone control by using a separate circulator and R845 Relay for each zone.
  • Include diaphragm powerhead and Micro Switch+ assembly that respond to temperature changes in boiler water.
  • Mount directly to boiler.
  • Select models include large transformers and extra terminals for supplying power to low voltage zone
  • Require 24 Vac thermostat with heat anticipator set at 0.2 A (plus current draw of gas valve on L8124E).
